Background: Increase in intimal medial thickness (IMT) of the carotid arteries is contemplated as a guide to atherosclerotic vascular disease and subclinical organ damage and foretell cardiovascular disease. The study aimed to analyse IMT in non-diabetic and diabetic subjects. Subjects and Methods: There were 105 diabetic and 95 non-diabetic subjects in this study. Common carotid artery (CCA) IMT was calculated using a linear probe of a high-resolution ultrasound medical system. Results: Diabetic subjects (0.95 mm) showed significantly higher mean intimal medial thickness (IMT) when compared non-diabetic subjects (0.85 mm) (p <0.05). Correlation of IMT was seen with age, total cholesterol, triglycerides, HDL & LDL cholesterol and systolic blood pressure (SBP) in diabetic subjects. Total cholesterol, SBP and diastolic blood pressure (DBP) showed a correlation with IMT in the non-diabetic subjects. Age, total cholesterol, SBP, and diabetes were independent risk factors for intimal medial thickness in multivariate linear regression analysis. Conclusion: Higher intimal medial thickness was seen in diabetic subjects when compared to non-diabetic subjects. We conclude that age, total cholesterol, SBP and duration of diabetes showed a significant correlation with IMT. IMT can be considered as a screening tool in diabetic patients for the early detection of atherosclerosis.

Background and aim: Systemic lupus erythematosus (SLE) is associated with increased risk of cardiovascular disease (CVD). Among many mechanisms, accelerated atherosclerosis, endothelial dysfunction, and hypercoagulability play a main role. Here, we investigate whether inflammatory, serological and clinical markers of SLE determine and correlate with arterial stiffness in SLE patients. Materials and methods: Routine blood samples, inflammatory mediators, specific antibodies, and 24 h proteinuria were measured in 43 SLE patients and 43 age and sex-matched controls using routine laboratory assays. We also assessed arterial stiffness by measuring radial artery applanation tonometry-derived augmentation index (AI), normalized AI (AIx@75), aortic pulse pressure, central systolic, diastolic and peripheral blood pressure. Results: SLE patients showed a significantly greater arterial stiffness vs. controls, as demonstrated by the significantly higher AIx@75 and aortic pulse pressure. Interestingly, regression analysis showed that age, systolic pulse pressure, inflammatory markers (erythrocyte sedimentation rate and C-reactive protein), daily dose of glucocorticoids, and cumulative organ damage positively correlated with arterial stiffness. Conclusions: SLE patients show increased arterial stiffness which correlates with markers of inflammation, that is involved in early alterations in arterial walls. Applanation tonometry can be used to screen SLE patients for subclinical vascular damage to implement prevention strategies for CVD.

Magnesium (Mg2+) levels are associated with insulin resistance, hypertension, atherosclerosis, and type 2 diabetes (T2DM). We evaluated the clinical utility of physiological Mg2+ in assessing subclinical cardiovascular organ damage including increased carotid artery intima- media thickness (c-IMT) and left ventricular mass index (LVMI) in a cohort of well-characterized adult non-diabetic individuals. Age- and gender-adjusted correlations between Mg2+ and metabolic parameters showed that Mg2+ circulating levels were correlated negatively with body mass index (BMI), fasting glucose, and 2h-oral glucose tolerance test (OGTT) glucose. Similarly, Mg2+ levels were significantly and negatively related to c-IMT and LVMI. A multivariate regression analysis revealed that age (β = 0.440; p < 0.0001), BMI (β = 0.225; p < 0.0001), and Mg2+ concentration (β = −0.122; p < 0.01) were independently associated with c-IMT. Age (β = 0.244; p = 0.012), Mg2+ (β = −0.177; p = 0.019), and diastolic blood pressure (β = 0.184; p = 0.038) were significantly associated with LVMI in women, while age (β = 0.211; p = 0.019), Mg2+ (β = −0.171; p = 0.038) and the homeostasis model assessment index of insulin resistance (HOMA-IR) (β = −0.211; p = 0.041) were the sole variables associated with LVMI in men. In conclusion, our data support the hypothesis that the assessment of Mg2+ as part of the initial work-up might help unravel the presence of subclinical organ damage in subjects at increased risk of cardiovascular complications.

Background: Hypertension-mediated organ damage (HMOD) is an emerging problem among young adults. The potential role of chronic immune-mediated inflammation in the pathogenesis of HMOD is increasingly being recognized. High-mobility group box 2 (HMGB2) is known for its role in the modulation of innate immunity and exerts signaling functions that affect various inflammatory diseases. However, the association between HMGB2 and HMOD in young adults remains unclear. Objectives: The aim of this study was to explore the association between HMGB2 and subclinical HMOD in young adults. Design: This is a cross-sectional study. Methods: Body composition, carotid ultrasound, carotid-femoral PWV (cf-PWV) measures, echocardiography, serum HMGB2 levels, and serum classic cardiometabolic risk factors were measured in 988 untreated young adults. We estimated the risk related to serum HMGB2 using multivariable-adjusted linear and logistic regression models. Then, we conducted a pathway overrepresentation analysis to examine which key biological pathways may be linked to serum HMGB2 in young adults with HMOD. Results: Among the 988 untreated young adults, we identified four distinct hypertension phenotypes: normotension (40.0%), white-coat hypertension (16.0%), masked hypertension (20.9%), and sustained hypertension (23.1%). High levels of serum HMGB2 were related to increased carotid intima-media thickness (cIMT) and left ventricular mass index (LVMI), higher cf-PWV and blood pressure, and a lower estimated glomerular filtration rate (eGFR). Linear regression analysis showed that serum HMGB2 was positively associated with cf-PWV and negatively associated with eGFR in all patients. Multivariate analysis showed that high levels of serum HMGB2 were associated with high odds of subclinical HMOD (damage in at least one organ). Biological pathway analysis indicated that patients with high serum HMGB2 levels had increased activity of pathways, related to endothelial dysfunction, inflammatory processes, and atherosclerosis. Conclusion: High serum concentrations of HMGB2 are associated with an increased risk of subclinical HMOD in untreated young adults.

The aim of the study was to assess the relationship between hypertensive target organ damage and vessel density (VD), foveal thickness, thickness of retinal nerve fiber layer, ganglion cell complex, and foveal avascular zone (FAZ) using optical coherence tomography angiography in a nonselected group of hypertensive children. One hundred fifty-seven children (56 girls) in mean age 14.9±2.9 years, in whom arterial hypertension was ultimately diagnosed were included in the study. FAZ, whole, fovea, parafovea superficial VD, whole, fovea, parafovea deep VD, foveal thickness, retinal nerve fiber layer, and ganglion cell complex were taken into analysis. Both absolute and standardized values of carotid intima-media thickness correlated with the larger FAZ area ( P =0.035, r =0.17; P =0.01, r =0.2, respectively). Subjects with increased carotid intima-media thickness had significantly larger FAZ ( P =0.024), reduced fovea superficial VD ( P =0.039), and foveal thickness ( P =0.007). Left ventricular hypertrophy and increased carotid-femoral pulse wave velocity were not associated with optical coherence tomography angiography parameters. Multiple linear regression revealed that the only determinant of FAZ and foveal thickness was higher carotid intima-media thickness–SD score, and for fovea superficial VD, the only determinant was central systolic blood pressure. In conclusion, hypertensive children present with signs of remodeling of microcirculation and decreased neural layer of retina associated with hypertensive macrocirculation remodeling expressed as increased carotid intima-media thickness and elevated central systolic blood pressure.

The analysis of literature data on ischemic damage to the brain and the organ of vision was carried out in order to study etiological factors, pathogenetic processes, parallel flow and mutual influence of two nosological forms: dyscirculatory encephalopathy and vascular optic neuropathy. According to the World Health Organization, there is much more people suffering from cardiovascular diseases: atherosclerosis, hypertension, diabetes mellitus and coronary heart disease. These diseases result in ischemic damage to a number of vital organs, including the central nervous system and the visual analyzer. Chronic vascular pathology of both the brain and the eye is one of the leading causes of patients’ life quality decrease of and their disability. The “triggering” causes of brain and eye damage, according to researchers, are cerebral atherosclerosis, elevating/fluctuating blood pressure, coronary heart disease, and carbohydrate metabolism disorders. Disorders of the systemic blood supply caused by these etiological factors lead to a progressive lack of oxygen supply to organs and tissues, followed by the development of intracellular and cellular hypoxia, and an ischemic intracellular cascade of biochemical disorders leading to dysfunction and sometimes cell death.In addition to direct hypoxic-ischemic damage of the nervous and visual systems cells, endothelial dysfunction contributes to the progression of these diseases, leading to a pronounced change in the wall at the level of small vessels, a change in its reactivity and a violation of the coagulation properties of blood, and as a consequence, to a gradual accumulation of ischemic and secondary degenerative changes in brain and eye cells.Knowledge of etiological factors and patterns of development of brain and eye combined ischemic damage can allow clarifying the complex of diagnostic measures, developing preventive measures, as well as prescribe pathogenetically justified treatment of existing pathology.

Objectives: Chronic kidney disease (CKD) is a well-established risk factor for cardiovascular diseases. Studies in adults have demonstrated the association between mildly decreased kidney function or even normal values of markers of kidney function to pulse wave velocity (PWV), a measure of arterial stiffness and a predictor of cardiovascular events. Our study aimed to evaluate associations between markers of CKD, PWV, and central haemodynamic parameters in children and adolescents at risk of subclinical kidney damage. Methods: 182 children and adolescents with hypertension, obesity, or hypercholesterolaemia (risk factors for subclinical kidney damage) were included in the study. The subjects were subdivided into 4 groups comprising children and adolescents with hypertension (group 1), obesity (group 2), hypercholesterolaemia (group 3), and a group with a combination of risk factors, such as obesity-related hypertension and metabolic syndrome (group 4). The study groups were compared to a group of healthy controls (group 5). PWV was measured by applanation tonometry (SphygmoCor, SCOR-Vx, Sydney, NSW, Australia) and laboratory parameters (serum creatinine, serum cystatin C, and microalbuminuria) were collected. Results: Pearson’s correlation coefficient demonstrated a statistically significant correlation between PWV and serum creatinine in group of all subjects (r = 0.220, p = 0.002). Further subdivision showed the correlation was significant in group 4 (r = 0.370, p = 0.002). In group 2 a correlation between PWV and cystatin C was found (r = −0.535, p = 0.009). In multiple regression analysis of all subjects with PWV as the dependent variable, age and diastolic blood pressure were statistically significant. Correlations between markers of kidney function and central haemodynamic parameters also showed significant correlations between serum creatinine and heart rate (HR) (r = −0.476, p < 0.001) as well as associated parameters (augmentation index, standardized at HR 75/min, ejection duration, and subendocardial viability ratio). Conclusions: Our study demonstrated a correlation between serum creatinine and PWV in children with combined risk factors for atherosclerosis and probable subclinical kidney damage. Further prospective research is needed to confirm the findings, and thus the preventive role of PWV determination in paediatric nephrology.

Aim. To assess the potential of Health Centres in identification of individuals at higher cardiovascular risk. Material and methods. In total, 1583 individuals (mean age 51,79±14,75 years) participated in a complex screening programme, including laboratory and instrumental examination. Results. The screening resulted in identification of individuals with high normal blood pressure (HNBP) and newly diagnosed arterial hypertension (AH) (prevalence 21%). In participants with HNBP, a combination of 2 risk factors (RFs) was the most prevalent (37,79%), while in people with newly diagnosed AH, a combination of 3 RFs was the most common (39,88%). The prevalence of autonomic dysfunction or “Myocardium” parameter increase, as an isolated RF, reached 8,84% and 9,45%, respectively. Abnormal ankle-brachial index (ABI) values were registered in 29,66% of the participants. In 18,97%, ABI values exceeded 1,3, while in 10,69%, they were under 0,9. ABI screening identified 11% of asymptomatic individuals with increased cardiovascular risk. Conclusion. A screening programme could identify individuals with preAH, primary autonomic dysfunction, functional myocardial instability, or subclinical atherosclerosis of peripheral arteries. Therefore, all subjects with increased cardiovascular risk require lifestyle modification and additional laboratory and instrumental examination, in order to assess the target organ damage and the need for pathogenetic therapy.

Objective Central systolic blood pressure (SBP) is a measure of arterial stiffness and strongly associated with atherosclerosis and end-organ damage. It is a stronger predictor of cardiovascular events and all-cause mortality than peripheral SBP. In particular, for children with congenital heart disease, a higher central SBP might impose a greater threat of cardiac damage. The aim of the study was to analyse and compare central SBP in children with congenital heart disease and in healthy counterparts. Patients and methods Central SBP was measured using an oscillometric method in 417 children (38.9% girls, 13.0 ± 3.2 years) with various congenital heart diseases between July 2014 and February 2017. The test results were compared with a recent healthy reference cohort of 1466 children (49.5% girls, 12.9 ± 2.5 years). Results After correction for several covariates in a general linear model, central SBP of children with congenital heart disease was significantly increased (congenital heart disease: 102.1 ± 10.2 vs. healthy reference cohort: 100.4 ± 8.6, p < .001). The analysis of congenital heart disease subgroups revealed higher central SBP in children with left heart obstructions (mean difference: 3.6 mmHg, p < .001), transpositions of the great arteries after arterial switch (mean difference: 2.2 mmHg, p = .017) and univentricular hearts after total cavopulmonary connection (mean difference: 2.1 mmHg, p = .015) compared with the reference. Conclusion Children with congenital heart disease have significantly higher central SBP compared with healthy peers, predisposing them to premature heart failure. Screening and long-term observations of central SBP in children with congenital heart disease seems warranted in order to evaluate the need for treatment.

Background: The remarkable success of clinical trials in mineralocorticoid receptor (MR) inhibition in heart failure has driven research on the physiological and pathological role(s) of nonepithelial MR expression. MR is widely expressed in the cardiovascular system and is a major determinant of endothelial function, smooth muscle tone, vascular remodeling, fibrosis, and blood pressure. An important new dimension is the appreciation of the role MR plays in immune cells and target organ damage in the heart, kidney and vasculature, and in the development of insulin resistance. Summary: The mechanism for MR activation in tissue injury continues to evolve with the evidence to date suggesting that activation of MR results in a complex repertoire of effects involving both macrophages and T cells. MR is an important transcriptional regulator of macrophage phenotype and function. Another important feature of MR activation is that it can occur even with normal or low aldosterone levels in pathological conditions. Tissue-specific conditional models of MR expression in myeloid cells, endothelial cells, smooth muscle cells and cardiomyocytes have been very informative and have firmly demonstrated a critical role of MR as a key pathophysiologic variable in cardiac hypertrophy, transition to heart failure, adipose inflammation, and atherosclerosis. Finally, the central nervous system activation of MR in permeable regions of the blood-brain barrier may play a role in peripheral inflammation. Key Message: Ongoing clinical trials will help clarify the role of MR blockade in conditions, such as atherosclerosis and chronic kidney disease.

Background: Both obstructive sleep apnea (OSA) and metabolic syndrome (MS) promote arterial stiffening. As a basis for this study, we presumed that arterial stiffness could be assessed using the Arteriograph (TensioMed, Budapest, Hungary) to detect early modifications induced by continuous positive airway therapy (CPAP) in reversing this detrimental vascular remodeling. Arterial stiffness is increasingly acknowledged as a major cardiovascular risk factor and a marker of subclinical hypertension-mediated organ damage. The aim of this pilot study was to evaluate the arterial stiffness changes in patients with moderate–severe OSA and MS after short-term CPAP use. Methods: We performed a prospective study that included patients with moderate–severe OSA and MS who had not undergone previous CPAP therapy. All subjects underwent clinical examination and arterial stiffness assessment using the oscillometric technique with Arteriograph (TensioMed, Budapest, Hungary) detection before and after 8-week CPAP therapy. Results: 39 patients with moderate–severe OSA were included. Eight weeks of CPAP therapy significantly improved central systolic blood pressure (Δ = −11.4 mmHg, p = 0.009), aortic pulse wave velocity (aoPWV: Δ = −0.66 m/s, p = 0.03), and aortic augmentation index (aoAix: Δ = −8.25%, p = 0.01) only in patients who used the device for a minimum of 4 h/night (n = 20). Conclusions: Arterial stiffness was improved only among CPAP adherent patients and could be detected using the Arteriograph (TensioMed, Budapest, Hungary), which involves a noninvasive procedure that is easy to implement for the clinical evaluation of arterial stiffness.

Arterial hypertension (AH) remains one of the main causes of disability and death worldwide, including in Russia. At the same time, the risks of coronary and cerebrovascular events increase in the presence of additional risk factors. The most common modifiable risk factors are metabolic disorders, including pre-diabetes, dyslipidemia, peripheral arterial atherosclerosis, and obesity, which also imposes certain features on the choice of optimal pharmacotherapy. Currently, the terminology of comorbid conditions continues to be discussed depending on their pathogenesis and the presence or absence of dominance of one disease over others, i.e. polymorbidity, comorbidity and multimorbidity. At the same time, “associative polymorbidity” is distinguished with a certain set of diseases that often occur in conjunction with each other with individual susceptibility of the body. One of the most common phenotypes of polymorbidity occurring in all age groups in both sexes is cardiometabolic, which is based on the formation of insulin resistance, sympathetic overactivity and chronic inflammation. This article provides a clinical example of the use of a fixed combination of angiotensin II receptor blocker telmisartan and calcium channel blocker amlodipine with the addition of an I1-imidazoline receptor agonist moxonidine in real clinical practice in a polymorbid cardiometabolic patient with target organ damage (left ventricular hypertrophy and microalbuminuria). High antihypertensive (favorable effect on 24-hour blood pressure, especially in the early morning) and organoprotective effectiveness of this combination, its possibilities in correcting additional risk factors (reduced heart rate, body weight and a positive effect on metabolic parameters), due to a synergistic effect on the central pathogenetic mechanisms of hypertension and obesity – insulin resistance and sympathetic overactivity.

Abstract Background Cumulative data from several studies suggest that HIV-infected populations have a 2-fold increased cardiovascular risk. Evidence is also pointing to a link between HIV and early vascular changes, including endothelial dysfunction and subclinical atherosclerosis. There is a paucity of data from sub-Saharan Africa (the epicenter of the global HIV burden and a region with a rapidly increasing cardiovascular disease [CVD] incidence); furthermore, the contribution of specific combination ART (c-ART) regimens to HIV-related CVD and early vascular changes remain unclear. Purpose To investigate the association between HIV-infection, c-ART (TDF+FTC+EFV), CVD risk and vascular markers of CVD in an adult cohort in South Africa. Methods Cross-sectional study, participants assigned to 3 groups: HIV-free (HIV−), HIV-infected ART naïve (HIV+/−) and HIV-infected on ART (HIV+/+). Data collection: demographic information, anthropometrics, CVD risk factors, and blood chemistry. Vascular endpoints assessed: brachial artery flow-mediated dilatation (FMD), carotid intima-media thickness (C-IMT) and retinal microvascular calibers. Results Cohort size: n=427 (HIV− n=148; HIV+/− n=69; HIV+/+ n=210), mean age: 39.4 years, 68.9% females. Analysis of cardiovascular risk showed no differences in smoking and alcohol consumption, and blood pressure was unaffected by HIV-status. The untreated HIV group had a high % participants with clinically low HDL-cholesterol levels, whereas c-ART seemed to reduce the prevalence (HIV+/−: 58% vs 31% in HIV− and 26% in HIV+/+; p<0.01). Prevalence of hyper-LDL-cholesterolemia and hypertriglyceridemia were similar. High sensitivity CRP levels were unaffected by HIV-status. Markers of end-organ damage showed renal involvement in the HIV+ groups (median regression of urine albumin-creatinine ratio in HIV+/+ and HIV+/− vs HIV−: Beta±SEM: 0.5±0.3 and 0.8±0.2 in HIV+/+ and HIV+/− respectively, p=0.02; adjusted for age, gender and ethnicity), as well as hepatic injury in the treated group (gamma-GT in HIV+/+ vs HIV−: Beta±SEM: 23.3±4.4, p<0.01, adjustment as above). Multiple regression of vascular markers showed increased FMD in HIV+/+ vs HIV+/− (Beta±SEM: 1.8±0.8, p=0.01; adjusted for age, gender, ethnicity and BMI), and decreased central retinal venular equivalent (CRVE) in HIV+/+ vs HIV+/− (Beta±SEM: −11.9±3.8, p=0.002) and vs HIV− (Beta±SEM: −7.1±3.2, p=0.03), adjustment as above. Carotid IMT was not affected by HIV or treatment status. Conclusions Combination ART consisting of TDF+FTC+EFV conferred vascular protection in HIV-infected participants as shown by improved endothelial function (increased FMD) and smaller CRVE compared to ART naïve counterparts. There was no evidence of subclinical atherosclerosis involvement (C-IMT). The vasculoprotective effects in the treated group were supported by a favourable HDL-cholesterol profile, despite unchanged inflammation (hs-CRP), and evidence of renal and hepatic impairment.

Objective of the study: This study aimed to test the effect of multiple cardiovascular risk factors on subclinical indices of atherosclerosis in children and adolescents with type 1 diabetes (T1D).Methods: Carotid intima-media thickness (cIMT), carotid distensibility coefficient (cDC), and carotid–femoral pulse wave velocity (PWV) were measured in children and adolescents with T1D, in a follow-up at the outpatient clinics of Verona. Blood pressure (BP; both central and peripheral), metabolic and other cardiovascular risk factors were evaluated in multivariate linear regressions to assess the association with the measured indices of subclinical vascular damage.Results: One hundred and twenty-six children and adolescents were included. cIMT was above the 95th percentile for age and height in 60.8% of the population, whereas 26% of the sample had cDC impairment (less than the 5th percentile) and 4.8% had an elevated PWV. Independent determinants of cIMT according to the regression models were only gender type of glucose monitoring and central systolic BP (cSBP). PWV was associated with age, sex, heart rate, and cSBP; cDC with age and both cSBP and, alternatively, peripheral BP (pBP). Neither pBP nor any of the tested metabolic parameters, including glycated hemoglobin, was associated with PWV and cIMT.Conclusions: A high proportion of early vascular damage, especially an increased cIMT, is present in children and adolescents with T1D in whom cSBP seems to be a common determinant. In children and adolescents with T1DM, a special focus should be on hemodynamic risk factors beyond metabolic ones.

Abstract Introduction The evolving use of multiplex proteomic platforms provides an excellent tool for investigating associations between multiple proteins and subclinical atherosclerotic disease. In this study, we evaluated the impact of a multiplex protein panel, on carotid intima-media thickness (cIMT) as a marker of subclinical atherosclerosis. Purpose We used a multiplex proteomic platform to identify possible associations between proteins and subclinical carotid atherosclerosis as measured by carotid ultrasound in an African population. Methods In the Sympathetic Activity and Ambulatory Blood Pressure in Africans (SABPA) study, 92 proteins from the Proseek Multiplex CVD III 96×96 (Olink Bioscience, Sweden) were analyzed in 378 participants (mean age 44.7±9.6 years, 50.6% women, 10.8% with known cardiovascular disease). Carotid ultrasound was performed for measurements of the carotid intima-media thickness (cIMT, mean 0.663±0.127 mm) and calculation of cross-sectional wall area (CSWA, mean 13.5±4.4mm2), a measure of target organ damage. Possible associations between the proteins, and cIMT and CSWA, respectively, were explored using linear regression models. A two-sided Bonferroni corrected P-value of 0.05/92=5.4x10–4 was considered statistically significant in the crude analysis. Results Of 18 proteins (1 standard deviation of change of ln-transformed values) that were Bonferroni-corrected (p≤5.4x10–4) significantly associated with cIMT and/or CWAS in crude analyses, the following remained significant after further adjustment for age, sex, waist circumference, systolic blood pressure, smoking and total cholesterol: growth-differentiation factor-15 (GDF15; β 0.017, p=0.050), E-selectin (SELE; β 0.019, p=0.017), carboxypeptidase A1 (CPA1; β 0.019, p=0.019), C-C motif chemokine 15 (CCL15; β 0.031, p<0.001), chitinase-3-like protein 1 (CHI3L1; β 0.021, p=0.007), the hemoglobin scavenger receptor (CD163; β 0.021, p=0.008) and osteoprotegerin (OPG; β 0.022, p=0.004). As for target-organ damage defined by CSWA, SELE (β 0.459, p=0.018), CCL15 (β 0.398; p=0.032) and CD163 (β 0.541, p=0.005) showed multivariate adjusted significant associations. Conclusion In an African population, we could confirm five proteins (GDF15, SELE, CHI3L1, CD163 and OPG) associated with cIMT, but in addition identified two proteins (CPA1 and CCL15) with novel associations with cIMT and/or CSWA.

Abstract Background Target organ damage (TOD) in essential hypertension relates to an adverse prognosis. Middle aged men are considered a population group where cardiovascular risk typically augments and erectile dysfunction (ED) that frequently accompanies both entities refers to a subclinical vascular damage process. Purpose To identify the optimal blood pressure (BP) levels in middle aged hypertensive males with ED in relation to TOD. Methods 258 ED males (mean age: 56 yo) with essential hypertension under medical treatment enrolled the study. All underwent 2D echocardiography and carotid ultrasound evaluation to determine left ventricular mass index (LVMI) and intima – media thickness (IMT) respectively. Carotid – femoral pulse wave velocity (PWV) and augmentation index (AIx) were also assessed as indices of central vascular stiffness and wave reflection physiology (complior & sphygmocor devices). Office brachial blood pressure (BP) measurements where performed according to the current guidelines and an average of three consecutive values was computed. Erectile dysfunction was assessed by using the SHIM-5 score (range 0–25, lower values display a pronounced dysfunction). Results In bivariate analysis brachial systolic blood pressure (bSAP) was positively and strongly associated with LVMI (r=0,6), PWV (r=0,65), AIx (r=0,67, all p<0,001) and IMT (p<0,05, r=0,55). Erectile performance as assessed by the SHIM-5 score was negatively related to PWV, AIX and IMT (r=−0,58, r=−0,45 and r=−0,65 all p<0,001) pointing out the underlying vascular detriment. Interestingly, there were no such correlations regarding the diastolic blood pressure values. Multiple linear regression analysis was performed and the relation of bSAP with LVMI, PWV, AIx and IMT remained significant after adjustment for age, BMI, smoking habits and presence of diabetes mellitus (all p<0,05). We further subdivided our population into three groups according to the values of office bSAP for normal blood pressure (≤129mmHg, n=143,55%), high normal (130–139mmHg, n=59, 23%) and high (≥140mmHg, n=56,22%). In patients with high-normal bSAP, the parameters of PWV and LVMI were significantly higher than in patients with normal BP (independent sample t-test, p: 0,032 and 0,016 respectively). Patients of the high bSAP group as expected, had more extensive cardiac and vascular damage (LVMI, PWV and AIx). Conclusion In essential hypertensive middle aged men with erectile dysfunction, guiding therapy toward normal systolic blood pressure values as compared to the high normal benefits target organ physiology. It is clinically important to identify this vascular patients group in order to adjust regimens and further therapeutic strategies.

Abstract Background Pulse wave velocity (PWV) and central blood pressure (CBP) have been intoduced into managment of hypertensive patients. PWV is positively correlated with arterial wall stiffness while central aortic pressure becomes better predictor of cardiovascular outcome than peripheral pressure. Reduction in CBP provides protective properties against subclinical organ damage. This work aims to investigate the effect of a new combination therapy of Amlodipine/Nebivolol (A/N) on central BP, peripheral BP and PWV. The results of using this combination will be compared to the well-established fixed-dose combination of Amlodipine/Valsartan (A/V). The study conducted between October 2018 and August 2020. One hundred and two hypertensive patients were assigned for Amlodipine 10 mg/Valsartan 160 mg combination therapy (A/V, n = 52) or Amlodipine 10 mg/Nebivolol 5 mg combination therapy (A/N, n = 50) by simple 1:1 randomization. Office, central blood pressure and PWV were measured on first (0 week), second (4–8 weeks) and third visit (10–12). Difference in BP (in each arm and between arms) was calculated along all visits. Results No statistical significant difference was found between A/V and A/N regarding age, gender, BMI and CV history. OBP, CBP and PWV were significantly reduced in each arm, but no differences were found when comparing both arm results to each other. Recorded side effects were insignificant. Conclusions The new combination therapy Amlodipine/Nebivolol (A/N) affords a significant reduction in CBP, PBP and PWV with minor and tolerable side effects. It has provided comparable results to Amlodipine/Valsartan (A/V) combination therapy.

Background: Lymphedema, abnormal lymphatic fluid accumulation in tissues, results in serious complications such as ulceration and reduces quality of life. Cancer treatment, through damage to lymph nodes and lymphatic vessels, is recognized as the main risk factor of lymphedema. However, understanding other risk factors is crucial for the prevention of lymphedema since there is no established curative treatment. Heart failure (HF) is considered an emerging risk factor for lymphedema through increased central and peripheral venous pressure, but the association of HF with incident lymphedema has not been systematically studied. Methods: In the Atherosclerosis Risk in Communities study, we included 9,895 individuals without prevalent lymphedema and cancer at visit 4 (1996-98) (n=9362 with no HF and n=533 with HF). Lymphedema was defined as two outpatient encounters (at least a week apart) or inpatient diagnoses through 2015 (ICD-9: 457.1 and ICD-10: I89.0). Participants without prevalent HF were categorized into two groups according to NT-proBNP, a marker of cardiac volume overload (>125 vs. ≤125 pg/mL [reference]), to acknowledge potential contribution of subclinical cardiac overload. Results: During a median follow-up of 17.7 (IQI 14.1-18.7) years, 149 participants developed lymphedema. 15-y cumulative incidence was higher in participants with HF and no HF with elevated NT-proBNP than those with no HF and non-elevated NT-proBNP (5.2% vs. 2.0% vs. 0.7%, respectively) ( Figure ). After accounting for potential confounders (e.g., body mass index, blood pressure, diabetes), the associations remained consistent (hazard ratios: 3.07 [95% CI 1.86, 5.08] for HF and 1.95 [1.33, 2.87] for no HF with elevated NT-proBNP). Results were consistent when using HF as a time-varying variable and censoring incident cancer. Conclusions: HF and subclinical elevation of NT-proBNP were associated with incident lymphedema, supporting the contribution of HF to the development of lymphedema.

Introduction: Childhood hypertension is an underestimated problem in India and other developing countries. It often leads to Hypertension in adult. Hypertensive children, although usually asymptomatic, already manifest evidence of target organ damage. Many of hypertensive children have left ventricular hypertrophy and increased carotid intima-media thickness, a marker of early atherosclerosis. Hypertensive children are very prone to develop target organ damage like retinopathy, renal damage, cardiac complications if remains undiagnosed and untreated for long. Other risk factors like cardiovascular disease, diabetes mellitus and hyperlipidaemia must also be looked for in hypertensive children. Aim: To study the prevalence, clinical profile, aetiology and to analyse various management protocol, complications, and early outcomes of hypertension in hospitalised children aged between 5-10 years. Materials and Methods: This was a prospective, observational analytical study conducted in the Department of Paediatrics of a Tertiary Care Centre at Ahmedabad, Gujarat, India, from 1st October 2017 to 30th September 2019. Blood pressure was measured by mercury sphygmomanometer using auscultatory method in all admitted patients in Paediatrics Department between the age of 5-10 years as a part of vital monitoring. A total of 103 patients having average systolic blood pressure and/or diastolic blood pressure greater than or equal to 95th percentile for that age, sex and height on three or more occasions were included in the study and their comprehensive details were recorded in prestructured proforma. The outcome was recorded as data in excel sheet and arranged in tables. Results: The prevalence of hypertension was 0.96%. The mean age of the study population was 8 years, and the male:female ratio was 1.09:1. Vomiting was the most common presenting complaint followed by fever and puffiness of eyes. A higher incidence of fever on presentation was due to the associated infective pathology of Central Nervous System (CNS). Pallor was the most common finding on general examination. Neurological deficit was observed in patients with hypertensive encephalopathy and stroke. Overall, 21 (20.38%) patients were in stage 2 hypertension, amounting to hypertensive emergencies, 48 (46.6%) patients with hypertension had an underlying renal disorder, followed by CNS disorder in 47 (45.6%). Amlodipine (26.21%) was the most common drug used in hypertensive patients. Most common complication of the present study was hypertensive retinopathy seen in 14 patients (13.59%). Conclusion: In hospitalised patients, the prevalence of hypertension was 0.96% with a male preponderance. On admission, the most prevalent complaints were vomiting and fever; pallor and puffiness of eyes were the most common general examination findings, and ascites was the most common systemic examination result. The most common secondary cause of hypertension was renal disease, with acute glomerulonephritis as most prevalent

Background: Left ventricular hypertrophy (LVH) is most commonly an indicator of target organ damage due to hypertension and may serve as a marker for chronicity of blood pressure elevation and as an indicator of the long-term burden of vascular risk factors. We assessed whether LVH measured by 12-lead ECG was associated with incident dementia in the Atherosclerosis Risk in Communities – Neurocognitive Study (ARIC-NCS). Methods: Our analysis included 12,665 individuals (23% black race, 56% female, mean age 57) who attended visit 2 in 1990-92. Cornell voltage (SV3 + RaVL) was derived from 12-lead ECG at visit 2 (1990-92), visit 3 (1993-95) and visit 4 (1996-98) as a continuous variable, and the gender-specific Cornell voltage criteria (SV3 + RaVL > 28mm for men, and >22mm for women) was used to define LVH as a dichotomous variable. Incident dementia was defined using a validated algorithm consisting of a full neuropsychological assessment, interviews, informant interviews, hospital discharge codes, or diagnostic codes from death certificates. A cox proportional hazards model was used to evaluate the association between LVH and incident dementia. LVH and Cornell voltage were modeled as time-dependent variables and covariates were updated at each visit. Follow-up time was from baseline until date of dementia, end of follow-up, or the end of 2013, whichever came first. Results: During a mean follow-up of 18 years, we identified 544 participants with LVH and 1195 incident dementia cases. LVH was associated with a higher risk of dementia: multivariable hazard ratio (HR) 1.91, 95% confidence interval (CI) 1.48-2.46 (Table). A 1-standard deviation increase in Cornell voltage (5 mm) was associated with a higher risk of dementia, HR (95% CI) = 1.10 (1.04-1.17). Conclusion: In this large population-based study, LVH measured in mid-life was associated with an increased risk of dementia. Additional research should confirm this association, and these results underscore the need for hypertension control to prevent subclinical brain injury.

Background: As a high-flow, low-impedance organ, the brain is sensitive to excessive pressure and flow pulsatility. Increased pulsatility and arterial stiffness are hypothesized to contribute to cerebral microvascular damage linked to cognitive impairment. The association of arterial stiffness with mild cognitive impairment (MCI) and dementia in a biethnic population is not well characterized, and the association of pressure amplification with MCI and dementia is relatively unexplored. Objectives: To quantify the cross-sectional association of arterial stiffness, measured by aortic pulse wave velocity (PWV), and pressure amplification with MCI and dementia in a biethnic population of older adults. Methods: We included 4,945 adults (2,903 females; 1,069 African Americans; mean age 75 years) from the population-based ARIC-NCS. The Omron VP-1000 plus system was used to measure arterial stiffness (carotid-femoral PWV (cfPWV)) and pressure amplification measures (central systolic blood pressure (cSBP), central pulse pressure (cPP), and pulse pressure amplification (PPA)). A neurologist and neuropsychologist classified MCI and dementia using psychometric assessments, medical history, cerebral magnetic resonance imaging, and physical examinations, with adjudication by a third reviewer. We used multinomial logistic regression to evaluate associations of race-specific 25th percentile cut points of PWV and pressure amplification with normal cognition (reference), MCI and dementia. We stratified by race and adjusted for age, sex, and heart rate, ApoE4, education, smoking status, and study center. Results: There were 760 Caucasians with MCI and 110 with dementia, and 201 African Americans with MCI and 47 with dementia. Among Caucasians, those with lower PPA had a higher prevalence of dementia, odds ratio (OR)=1.84 (95% confidence interval (CI): 1.15, 2.97), comparing participants below the 25th percentile to those above it, and those with higher cSBP had a higher prevalence of MCI, OR=1.33 (95% CI: 1.09, 1.63), comparing participants above the 75th percentile to those below it. Also among Caucasians, those with higher cPP had a higher prevalence of MCI, OR=1.25 (95%CI: 1.01, 1.55), and dementia, OR=1.66 (95% CI: 1.00, 2.73), comparing participants above the 75th percentile to those below it. There were no statistically significant associations with cfPWV, among African Americans, and no evidence for effect modification by hypertension or diabetes. Conclusion: Arterial stiffness and components of pressure amplification were associated with MCI and dementia in Caucasians but not in African Americans, possibly due to the limited sample size. Longitudinal characterization of the observed associations is warranted to determine whether these measures are independent predictors of MCI and dementia among Caucasian and African American older adults.

Background: The retinal microvasculature measured non-invasively by fundus photography enables examination of the role of small blood vessels in cerebrovascular disease since changes in retinal vessels may mimic that of cerebral arterioles. The association of arterial stiffness measured by pulse wave velocity (PWV) and retinal vessel diameters in a population sample is unknown, and evaluation of segment-specific PWV and retinal vessel diameters has not been conducted. Objectives: To quantify the cross-sectional association of PWV with retinal vessel diameters in a population of older adults. Methods: We examined data on PWV and retinal photography in 1,538 adults (853 females; mean age 77 years) from the population-based ARIC-NCS after excluding 43 participants with retinal diseases and 46 with missing covariates. Technicians used the Omron VP-1000 plus system following a standardized protocol to measure carotid femoral (cfPWV), brachial-ankle (baPWV), heart-femoral (hfPWV) and femoral-ankle (faPWV) twice and averaged the results. Non-mydriatic retinal fundus photography of both eyes were obtained and digital images were centrally processed with computer software to calculate central retinal arteriolar equivalent (CRAE) and central retinal vein equivalent (CRVE), which reflect diameters of retinal arterioles and venules, respectively. We used data from a randomly selected eye, and if missing, the non-missing eye was used (n=490). The relationship of PWV and CRAE and CRVE was assessed by multivariable linear regression adjusted for age, gender, race, hypertension, diabetes and smoking (current or former vs. never). Results: PWV was not associated with CRAE. The association of faPWV and CRVE was modified by gender. Among males, faPWV (cm/sec) was negatively associated with CRVE (beta= -0.01 μm, 95% confidence interval (CI): -0.02 to -0.006). This pattern was not observed among females. The association of baPWV and CRVE was modified by gender and smoking in which baPWV was only associated with CRVE in male smokers (current and former). Among male smokers, baPWV (cm/sec) was negatively associated with CRVE (beta= -0.002 μm, CI: -0.02 to -0.008). Interactions were robust to additional adjustment for systolic blood pressure, heart rate and body mass index. No association was observed between cfPWV and hfPWV with CRVE. Conclusion: Arterial stiffness was not associated with retinal arteriole diameters in older adults, but peripheral measures of arterial stiffness were associated with retinal venular diameters in males and male smokers. Whether peripheral stiffness plays a role in microvascular changes or has a shared mechanistic pathway with smoking among males requires additional investigation. The different associations of PWV and retinal measures suggest diverse pathogenic processes are involved in macrovascular and microvascular changes preceding end-organ damage.
