Full textIntroduction: Type 2 Myocardial infarction (MI)has been recently defined as an imbalance between oxygen supply and demand, in the absence of atherothromthrombosis. This work aimed to describe the main etiolgies as well as epidemiological, clinical and prognostic characteristics.Method: Data from patients with type 2 MI were collected from the RICO cohort (Observatoire des Infarctus de Cote d'Or). In a complementary work, we analyzed the retrospective data of the emergency department of Dijon University Hospital.Results: Among 4,436 consecutive patients hospitalized for MI in Dijon emergency department over 3 years, 947 (21%) had type 2 MI (median age: 81 years). In the RICO cohort, 4,572 consecutive patients, including 862 (19%) type 2 MI were included over 5 years (median age: 77 years). Intra-hospital mortality after type 2 MI was 14% among ED patients and 11% for RICO patients. The most common chronic conditions predisposing to type 2 MDI were severe anemia and severe aortic stenosis. An acute infection, from the respiratory tract for rougly 2/3 of them, was found in 10% of all MI in the RICO database, and was by far the most common precipitating factor in the pathogenesis of type 2 MI. Concerning therapeutics, after adjustments on propensity scores, red blood cell transfusion was associated with a one-year mortality reduction for patients >80 years of age with a hemoglobin nadir ≤ 8 g/dL. In Post-infectious PI, percutaneous coronary intervention was not associated with a better prognosis than drug treatment alone (one-year mortality of 24% vs 19%, p = 0.5).Conclusion:Type 2 MI is an underdiagnosed condition, representing 20% of all MI, and is common in the elderly. It is associated with an over-risk of mortality compared with type 1 MI. Acute infections, particularly from the respiratory tract, are the most common triggering factor. Based on observational data, invasive procedures do not appear to be associated with improved prognosis

Full textIntroduction : Type 2 myocardial infarction (MI) resulting from an imbalance between oxygen supply and demand, in the absence of atherothrombosic phenomenom, remains an enigmatic clinical entity. This work aimed to precise type 2 MI epidemiological and prognostic features, especially the key role of coronary artery disease (CAD), and to appraise the clinical and prognostic relevance of a new classification of MI proposed by de Lemos.Method : Using the Observatoire des Infarctus de la Côte d'Or (RICO), we collected data from patients hospitalized for MI, including differentiation between type 1 (T1MI) and type 2 MI (T2MI), after adjudication of type 1 MI and type 2 MI, and sub-groups according to the new classification, with categorization of T2MI into those with (T2AMI) or without (T2BMI) obstructive coronary artery disease (CAD). We also conducted a systematic review of the literature on the role of obstructive CAD in T2MI using the PubMed® database. Finally, we analyzed data from the REgistre des InfArctus de CôTe d'IVoire (REACTIV) at the Abidjan Heart Institute, in order to identify the specific features of type 2 MI in this Sub-Saharan Africa population.Results : Among the 4573 patients included in RICO over a 5-year period, 3806 (81.1%) and 767 (18.9%) had T1MI and T2MI after reclassification, respectively. Obstructive CAD was identified in 68.6% of patients with T2MI. T2AMI affected older patients (median age 78 yo), with more comorbidities, and is associated with poorer outcomes after 1-year follow-up, compared with T2BMI and even T1MI due to atherothrombosis (T1AMI). Our data show a 40% excess all-cause mortality at 1-year (HR 1.362; IC95% 1.029-1.802) in T2AMI versus T1AMI. Based on the systematic review of the literature, we found a wide range of CAD prevalence in type 2 MI (between 30% and 92%), depending on definition criteria, diagnostic tools and populations studied. In patients admitted to the emergency department, history of obstructive CAD was an independent predictor of T2MI versus T1MI, increasing this probability by 40% (OR 1.38; 95%CI 1.08-1.77). Finally, of the MI patients included in REACTIV registry over 4 years, 62 (14.1%) met the definition of T2MI. Patients with T2MI were slightly younger (54 vs. 58 years, p = 0.09) with fewer conventional CV risk factors. Patients with T2MI had less severe CAD, with less 3-vessel CAD (p < 0.001). The main triggering factors for T2MI in this Sub-Saharan population were coronary embolism (24.2%), severe hypertension ± left ventricular hypertrophy (22.6%) and tachyarrhythmia (16.1%).Conclusion : Our work support the hypothesis of epidemiological and pathophysiological heterogeneity of T2MI, despite it is increasingly considered as a geriatric condition. Furthermore, we suggest that the identification of CAD, which is highly prevalent, could improve the characterization and risk stratification of type 2 MI, and help target interventional studies to improve its management and outcomes

Full textCardiovascular disease remains a leading cause of mortality in industrialized countries. Loss of cardiomyocytes via apoptosis is believed to contribute to the continuous decline of the ventricular function in heart failure. Several investigations revealed that following ischemia-reperfusion (I/R), cardiomyocytes apoptosis is controlled, at least, by the Bcl-2 proteins family members. The excessive reactive oxygen species (ROS) production, through NADPH oxidase, contributes also to cellular damages and death. Recently, erythropoietin (EPO), a hematopoietic cytokine, has been shown to protect heart exposed to ischemia or ischemia-reperfusion, limiting infarct size and cardiac remodeling. However, to date the precise cellular mechanism of DA-induced cardioprotection remains incompletely understood. Thus, the aims of this work were 1) to assess the short and long term cardioprotective effects of darbepoetin-a (DA), an Epo analog, in an in vivo rat model of I/R ; 2) to investigate the signaling pathway through which DA potentially limits apoptosis and ; 3) to elucidate whether its cardioprotective effect, and more particularly its antioxidative effect, is linked to an HO-1-dependent inhibition of the NADPH activity. In the first study, left ventricle infarct size (LV) was smaller than that in the control rats, in agreement with echocardiographics parameters. DA-treatment activated the JAK2/Akt signaling pathway, lowered cleaved caspase-3 and increased both P-Bad and P-GSK-3ß proteins. This was consistent with the decrease of ROS production and the lowered binding of Bad to Bcl-xL and Bcl-. Similarly, in long term study, histology alterations implicated lower LV cardiac fibrosis and greater capillary density; furthermore both Bcl-xL and Bcl-2 were upregulated. In the second study, both LVSF and LVEF were higher versus control and DA+ZnPP, a heme-oxygenase-1 (HO-1) inhibitor, matching with the decreased LV infarct size in DA rats. DA induced HO-1 and down regulated the expression of p47phox and the activation of Rac1, both regulatory subunits of the NADPH-oxidase. This was consistent with the decrease of ROS production and these DA effects were inhibited by ZnPP. Further experiments in humans are now required to prove benefits effects of DA and to promote the use of EPO as therapeutics in heart infarction

Full textAdipose tissue plays a central role in the onset of type 2 diabetes (T2D). Adiponectin (ADIPOQ) and interleukin 6 (IL6), two adipokines, are major players in the onset of T2D and vascular complications related to T2D. PPARgamma is a transcriptional factor involved in the adipogenesis and the expression of IL6 and ADIPOQ. Our aim was to assess the impact of PPARG, ADIPOQ, IL6 polymorphisms (SNPs) on the prospective risk of T2D (in the DESIR study) and vascular complications related to T2D (in the DIABHYCAR study). The DESIR cohort is a 9-year follow-up study. Participants were recruited from the French general population. Participants from the DIABHYCAR study had type 2 diabetes and a high vascular risk. DIABHYCAR participants were followed for 4 years in average. In the DESIR cohort, 12Ala, 1431T alleles of PPARG and -11391G allele of ADIPOQ were associated with the onset of hyperglycemia over a 6-year period. The -174C allele of IL6 was associated with the onset of T2D over a 9-year period. In this latter cohort, we showed an interaction between Pro12Ala and C1431T SNPs of PPARG on the body mass index. In the DIABHYCAR cohort, +45G and +276G alleles of the ADIPOQ gene were associated with an increased risk of myocardial infarction. The -11391A and +45G allele of the ADIPOQ gene were associated with an increased risk of renal disease and with an increase increatinine levels during the follow-up. The -174 G>C SNP of the IL6 gene is not associated with the risk of cardiovascular disease or renal events. In summary, genetic variations of ADIPOQ, IL6 and PPARG are associated with the prospective risk of T2D and/or vascular complications related to T2D

Full textIn the first part, we were interested in the criteria of oxygen supply/demand imbalance involved in the occurrence of a type 2 infarction. We explored in 610 patients the association between the parameters of these criteria and the occurrence of acute myocardial injury and type 2 infarction, as well as the correlation between these parameters and the extent of myocardial injury. Our results did not show any association between the importance of oxygen mismatch and the occurrence of acute myocardial injury. There was also no correlation with the magnitude of such injury. Therefore, we could not define strict restrictive thresholds that could be considered a significant myocardial stressor. In the second part, we compared the short-term and the long-term outcomes of patients admitted with an oxygen supply/demand imbalance condition according to the presence of myocardial injury or type 2 infarction and assessed the association of these pathological entities with mortality and major cardiovascular events. In this population of 824 patients, the occurrence of myocardial injury or type 2 infarction led to high in-hospital mortality of more than 20% and was significantly associated with it after adjustment for patient characteristics. In the follow-up of survivors, the outcome was dependent on comorbidities without the involvement of the occurrence of these initial myocardial injuries, with mortality rates of 27 to 35% and major cardiovascular events of 23 to 40%. We proposed to compare these results in another study, conducted prospectively, with a standardized 6-month follow-up of patients admitted for oxygenation failure, the methods of which are detailed here. This cohort consists of 670 patients whose data are currently being analyzed. Finally, in the third part, we focused on the 675 elderly patients, who represent more than 80% of our cohort, to determine the factors associated with the occurrence of these myocardial injuries and type 2 infarction according to age classes. We found very dependent patient profiles in these classes, linked to the epidemiological changes of aging. However, the individualization of type 2 myocardial infarction within acute myocardial lesions was not obvious, nor was the impact on mortality, which was essentially based on the burden of comorbidities

Full textType 2 diabetes mellitus (T2DM) is a multifactorial, chronic, progressive disease, affecting more than 422 million people over the world, and having a significant societal and economic impact. Cardiovascular disease is the leading cause of morbidity and mortality in T2DM patients, who have higher rates of mortality than the non-diabetic population. T2DM is defined by its metabolic -mainly glucose-related- manifestations which serve as markers for controlling the evolution of disease. However, while the effect of control serum glucose levels on microvascular complications is acknowledged, its impact on macrovascular complications remains uncertain. Since 2008, new blood glucose-lowering agents have to demonstrate cardiovascular safety, and some have shown to reduce cardiovascular outcomes and mortality. However, the populations included in these large cardiovascular outcome trials differ from the general population, making results no fully generalisable. While randomised controlled trials are the gold standard for generating scientific evidence, observational studies conducted with secondary data of Electronic medical records (EMRs) are increasingly used as a source of complementary or confirmatory evidence, especially when RCTs are not feasible or unavailable. This work report an observational, population-based cohort study conducted in SIDIAP, a large Catalan general practitioners database that contains health data of 5,5 million people. We assessed cardiovascular outcomes and mortality in general, unselected T2DM population treated with non-insulin blood-glucose-lowering agents. The results are expected to be useful both for clinical and public health decision-making

Full textObjectives Patients admitted to intensive care units with sepsis are at high risk of thrombotic events (TEs) throughout the circulatory systems (systemic, coronary, and pulmonary). We aimed to investigate the thrombotic risk during sepsis (i) within the systemic circulation in patients with new-onset atrial fibrillation (NOAF), (ii) within the coronary circulation in patients with acute myocardial infarction (MI), and (iii) within the pulmonary circulation in patients with severe COVID-19. Furthermore, while the risk of TE raises the question of whether thromboprophylaxis doses should be escalated, assessment of associated bleeding risk should be systematic in order to establish the benefit/risk balance of such treatment. Methods We investigated the risk of major cardiovascular events (risk characterization and stratification), including AT, major bleeding and death in three populations of septic patients with NOAF, MI or severe COVID-19 by studying (i) markers such as left atrial dysfunction on transesophageal echocardiography (TEE) and cardiac troponin, and (ii) thrombotic and hemorrhagic risk scores used in cardiology patients. We conducted a practice survey on thrombotic risk management in patients with de NOAF during sepsis. Finally, we carried out two therapeutic trials: the CAFS (Control Atrial Fibrillation Sepsis) multicenter, randomized, controlled superiority trial comparing three usual strategies to prevent hemodynamic risk with NOAF during septic shock (currently being included), and the ANTICOVID (ANTIcoagulation in patients with hypoxemic COVID-19 pneumonia) multicenter, randomized, controlled superiority trial comparing three anticoagulation strategies with dose escalation in patients with hypoxemic COVID-19 pneumonia Results Our work confirmed the high risk of major cardiovascular events during sepsis. In patients with NOAF, cardiological approaches to thrombotic (TEE abnormalities, CHA2DS2-VASc score) and hemorrhagic (HAS-BLED score) risk stratification seem limited. An individualized approach with TEE based on the CHA2DS2-VASc score could nevertheless be of interest. This work also better characterized the risk of intra-cardiac thrombus formation (absence of thrombus within 48 h of AF onset, low prevalence of post-cardioversion left atrial stunning). Finally, we confirmed the heterogeneity of hemodynamic and thrombotic risks management, calling for randomized trials. In patients with MI during sepsis, cardiological approaches to thrombotic risk stratification (GRACE and TIMI scores) also appear limited. In usual practice, an invasive strategy involving early coronary revascularization is very uncommon. In patients investigated using coronary angiography, the incidence of obstructive coronary artery disease is high. In patients with hypoxemic COVID-19 pneumonia, high-dose prophylactic anticoagulation, provided a better net clinical benefit driven by a 4-fold reduction in de novo thrombosis rate with no increase in major bleeding compared with standard-dose prophylactic anticoagulation. Also, therapeutic anticoagulation did not provide additional benefit in comparison with high-dose prophylactic anticoagulation. Conclusions On the basis of the common pro-thrombotic pathophysiology described in septic conditions, our work has made it possible to (i) better characterize clinical situations at particularly high thrombotic risk (NOAF, MI, severe COVID-19 infection), (ii) develop individual therapeutic strategies for thrombotic risk prevention (COVID-19), and (iii) establish the basis for subsequent trials in specific intensive care populations at very high thrombotic risk
