Abstract (sommario):

AbstractMany religious traditions ascribe to the term "heart" a meaning that goes beyond the physical and the emotional levels. In Hinduism, the discovery of the spiritual heart is generally seen as a precursor to higher experiences that transcend the mind and the senses, and culminate in the vision of God. This essay briefly describes the Hindu view of the spiritual heart, where the heart is located, and how it is experienced.

Abstract (sommario):

AbstractS3 is a low-pitched sound (25–50Hz) which is heard in early diastole, following the second heart sound. The following synonyms are used for it: ventricular gallop, early diastolic gallop, protodiastolic gallop, and ventricular early filling sound. The term “gallop” was first used in 1847 by Jean Baptiste Bouillaud to describe the cadence of the three heart sounds occurring in rapid succession. The best description of a third heart sound was provided by Pierre Carl Potain who described an added sound which, in addition to the two normal sounds, is heard like a bruit completing the triple rhythm of the heart (bruit de gallop). The following synonyms are used for the fourth heart sound (S4): atrial gallop and presystolic gallop. S4 is a low-pitched sound (20–30 Hz) heard in presystole, i.e., shortly before the first heart sound. This produces a rhythm classically compared with the cadence of the word “Tennessee.” One can also use the phrase “A-stiff-wall” to help with the cadence (a S4, stiff S1, wall S2) of the S4 sound.

Abstract (sommario):

Early investigations into amphibian lymph heart function established that lymph heart contractions were synchronous with neither the systemic heart, nor the lungs, nor each other. However, the present study concludes that there is synchronization between the cardiac heart and the lymph hearts and that the posterior lymph hearts in both Rana catesbeiana Shaw, 1802 and Bufo marinus (L., 1758) beat synchronously as well. Pressure peaks were recorded through cannulation of the ischiatic artery and each posterior lymph heart and subsequently analyzed to determine the time differences between arterial diastole and lymph heart systole or between two bilateral lymph heart systoles. Results show that there is clear synchronization between the lymph heart systoles of two bilateral posterior lymph hearts. This lymph heart synchrony is further supported by using Poincaré plot analysis to visually compare the lymph heart inter-beats. Cardiac heart and lymph heart contractions also show a degree of synchronization, even though the lymph hearts beat up to three times as fast as the cardiac heart. These results support the conclusion that synchrony is characteristic of the anuran lymphatic system and that synchronization of the cardiac heart and the lymph hearts could impart an energetic advantage that benefits fluid homeostatic mechanisms.

Abstract (sommario):

Heart failure is a common and serious chronic condition, which can be as ‘malignant’ as most forms of cancer (Stewart, MacIntyre, Hole, Capewell, & McMurray, 2001). Recent estimates are that around 40,000 men and 45,000 women are living with heart failure in Scotland (Stewart, MacIntyre, Capewell, & McMurray, 2003). Heart failure is significantly influenced by socioeconomic factors, with people on lower incomes being more likely to develop, and die faster from, heart failure (McAlister et al, 2004). There is a growing body of research on the experience of living with heart failure, however, none provides serious consideration of the role of socioeconomic factors in impacting the experience of heart failure, and some qualitative research may actually obscure such factors. There were two main aims in this thesis. One was to explore how qualitative research methods can better consider the relationship between experience and broader context, such as the influence of socio-economic factors on health. The other aim was to examine the experiences of people as they live with and die from heart failure in ways that situate their accounts in the broader context of their lives. An initial research study, on which I was the main researcher, focused on the experiences of 30 people living with advanced heart failure. These people, their carers and key health professionals were interviewed, where possible, three times over a six months period. This thesis re-examines that study, focusing on 20 of those participants, for which a total of 122 interviews were conducted. I used a dialogical approach to see whether the socioeconomic context of heart failure for these respondents, could be captured through exploring experiences, performance, relationships, discourses and institutional practices, the social processes that mediate the relationship between socioeconomic disadvantage and chronic diseases were explored. This offers important learning in relation to the experience of living with heart failure, along with the experience of providing care. The findings highlight the need to broaden our view of chronic illness beyond biomedical approaches, and grow our methodological approaches along with that, in order to develop knowledge and practice that has relevance for people who live with and die from heart failure.

Abstract (sommario):

Insomnia is one of the most common complaints in medical practice and the sleep disorder of highest prevalence. At least 10% of the worldwide population has chronic insomnia, which has been associated with a range of negative health outcomes. Within the clinical setting, patient subtypes have been defined according to symptomology. More recently insomnia researchers have proposed phenotypes based on total sleep time during overnight polysomnography (PSG). Short-sleeping insomnia patients are purported to be a biologically severe phenotype at higher risk of cardiovascular morbidity, poor mental health, and obesity (compared to healthy controls). Heart rate variability (HRV) is an objective marker that provides insight into autonomic nervous system dynamics. The overarching aim of my research was to explore a large clinical sample of patients with Insomnia Disorder to determine whether differences in HRV exist during sleep in empirically-derived insomnia patient subtypes. The aim of the work presented within Chapter 2 was to identify all previous insomnia-HRV research to determine if HRV was impaired in adult patients with insomnia, and whether treatments altered HRV. A systematic review of five web databases located 22 relevant articles; 17 case-control studies and 5 interventions studies. Results were difficult to synthesise due to incomparable methodology and reporting. There was a high risk of bias in the majority of studies. It was concluded that although HRV impairment in insomnia may be a widely-accepted concept, it is not supported by research nor has it been determined if it varies after treatment or according to patient subtype. The aim of the first empirical study of the thesis (Chapter 3) was to objectively-derive insomnia patient subtypes and evaluate their physiological signals (HRV and electroencephalography [EEG]) during sleep onset. Patients (n = 96) with clinically-diagnosed Insomnia Disorder underwent overnight PSG to determine sleep metrics for cluster analysis using Ward’s method: Total Sleep Time (TST), Wake After Sleep Onset (WASO) and Sleep Onset Latency (SOL). Electrocardiogram (ECG) from the PSG was extracted in the 10 minutes before and after sleep onset. After R-wave detection, the ECG was visually checked and manually corrected as required. Six time and frequency-domain HRV measures were analyzed; heart rate (HR), standard deviation of all N-N intervals (SDNN), root mean square of successive R-R intervals (RMSSD), percentage of successive R-R intervals that differ by > 50 ms (PNN50), high frequency (HF), and low frequency (LF)/HF ratio. Cluster analysis derived two solutions; one comprising two subtypes and another with three subtypes. The two cluster solution consisted of insomnia with short-sleep duration (I-SSD: n = 43) and insomnia with normal objective sleep duration (I-NSD: n = 53). At sleep onset, between-group HRV analysis revealed reduced parasympathetic activity (PNN50 and RMSSD) in the short-sleeping subtype. This was not mirrored by significant increases in HR and/or the LF/HF ratio. These findings suggested that reduced parasympathetic activity during sleep onset might contribute to poor cardiometabolic health outcomes previously reported in short-sleeping insomnia patients. The final component of this thesis was a case-control study (Chapter 4) which examined whether HRV measures differed between insomnia subtypes across the nocturnal period. It was hypothesized that short-sleeping insomnia patients would have impaired HRV compared to normal-sleep duration insomnia patients, consistent with differences observed at sleep onset (Chapter 3). Insomnia patients underwent overnight PSG, which provided sleep metrics for cluster analysis and ECG for HRV analysis. ECG was visually checked for accurate R-wave detection, and manually corrected as required. HRV analysis was performed from lights-off to lights-on (and separately by sleep/wake stage) using time and frequency-domain measures. Differences in HRV measures (HR, SDNN, RMSSD, LF, HF, LF/HF) were tested between the subtypes using General Linear Models controlling for age as a core confounder. Short-sleeping insomnia patients (I-SSD: n = 34; 45.5 ± 10.5 years) and normal-sleep duration insomnia patients (I-NSD: n = 41; 37.6 ± 10.9 years) were included in the HRV analysis. There were no statistically significant nocturnal HRV differences between subtypes after controlling for age. As such, short-sleeping insomnia patients did not have statistically significant reductions in HRV measures representative of parasympathetic activity.«br /» In summary, there was a lack of persistent nocturnal HRV disparities (between empirically-derived insomnia patient subtypes) that extended beyond sleep onset in this large clinical sample of patients with Insomnia Disorder. The central tenet of 24-hour hyperarousal amongst short-sleep duration insomnia patients cannot be supported by the combined findings of these two empirical studies. Post-hoc calculations revealed larger sample sizes would be required to determine a small to medium effect size difference in nocturnal HRV between insomnia patient subtypes. Until this time, the directional relationship between insomnia, heart rate variability, hyperarousal and cardiovascular disease remains unclear in the heterogeneous insomnia population.

Wheeldon, Dereck Ronald. "Donor heart preservation for heart transplantation". Thesis, Open University, 1997. http://oro.open.ac.uk/57723/.

Testo completo

Abstract (sommario):

Heart transplantation has enjoyed a spectacular success over the past 25 years. Prior to 1980 less than 350 operations were carried out with an overall one year survival of less than 60%. In 1995 more than 3,000 transplants were performed with a one year survival of 83%. However, growth and improved survival have both plateaued over the last few years; the former because of the falling donor supply and the latter, in part, because of the use of less suitable donors in an effort to offset the problem of supply. Much attention has been focused on the drama of the surgery and the intricacies of immunological manipulation whilst little effort has been devoted to the area of donor management, despite the fact that primary graft failure is responsible for as many post transplant deaths as either infection or rejection. Optimum preservation of the donor heart has also provided a difficult challenge, such that, despite a considerable scientific effort little advance has been achieved to extend the 4 hour safe storage limit which has remained in place over the past 20 years. In this dissertation the problem has been approached by combining laboratory based preservation models with an objective regime of donor management. A sensitive isolated small animal working heart model was developed and used to characterise cardioplegic induction. Subsequently, the model was used to examine the interaction of oxygen content with the mode of delivery, during preservation. Finally, a number of representative solutions were combined with the most promising oxygen delivery method. These studies served to illustrate the utility of controlled laboratory studies and offer the prospect of more than doubling post storage function. The development of a rigorous donor management regime was also shown to be capable of reducing the variance in haemodynamic parameters by up to 44% whilst safely increasing the donor pool by approximately 30%. It is the contention of this thesis that the only prospect of improving the current impasse with the supply of donor hearts in sufficient quantity and of acceptable quality, is by the combination of appropriate laboratory models with controlled clinical trials.

Abstract (sommario):

Heart failure patients have dysfunction of the cardiac conduction system that contributes to a high burden of arrhythmias including atrial fibrillation and sudden cardiac death. Heart failure has been associated with the inflammatory response, but it is unknown if inflammation is playing a role in the remodelling of the cardiac conduction system in heart failure. Inflammation has been shown to be present in the myocardium from failing hearts and it is known to have detrimental effects on cardiac function, inducing fibrosis, remodelling of ion channels and even arrhythmias. However, the effect of inflammation on the cardiac conduction system has not been investigated. The aims of this study were to determine if there is an increase of pro-inflammatory cytokines and inflammatory cells in the cardiac conduction system in heart failure. In addition, to identify if there is possible inflammation-associated fibrosis and apoptosis in the cardiac conduction system in heart failure. To test these aims, three models of heart failure were used: a rat model of pulmonary arterial hypertension, a rabbit model of congestive heart failure and a rat model of myocardial infarction. In the rat model of pulmonary arterial hypertension there was a bradycardia, a prolongation of the QT interval, and an increase in the atrioventricular and ventricular refractory periods, suggesting electrical remodelling in these animals. The rats with pulmonary arterial hypertension displayed an increase in pro-inflammatory cytokines such as interleukins 1β and TGFβ in the right side of the heart, including the sinoatrial node and right Purkinje fibres of the cardiac conduction system. In addition, in these areas, there was an increase in components of the extracellular matrix, including fibronectin, collagen I and vimentin. Histology revealed regions of non-myocyte nuclei, only in the right ventricle of the rats with pulmonary arterial hypertension. Immunohistochemistry demonstrated patches of CD68 and vimentin expression (markers for macrophages and fibroblasts, respectively) in the right side of the heart in these animals. TUNEL staining also revealed an increase in apoptosis in the right side of the heart. In the rabbit model of congestive heart failure, the region most affected by inflammation was the right atrium, while few changes were measured in the ventricles or cardiac conduction system. Although these results are surprising, it is suggested that the atria could be more sensitive to the physical stretch produced in this model. In the rat model of myocardial infarction, there were regions of non-myocyte nuclei in the border zone. This region also had increases in pro-inflammatory and fibrosis markers. In conclusion, this work has presented the novel finding that there can be inflammation in the cardiac conduction system in heart failure. This could be contributing to the arrhythmias seen in heart failure patients. This could possibly lead the way to anti-inflammatories as a possible novel therapeutic for heart failure patients.

Abstract (sommario):

Pediatric congenital heart defects primarily occur during fetal heart embryological development. This purpose of this thesis was to provide a comprehensive review of the basic cardiovascular physiology, focusing on three separate components - the heart, the blood vessels, and the blood - and a current look at three common occurring conditions. The congenital heart defects are reviewed with an anatomical overview of the condition, patient presentation, current surgical repairs, and life expectancies following successful repair. Repairs of tetralogy of fallot report mortality rates below 3%, compared to a 50% mortality rate prior to development of surgical repairs (Apitz). Transposition of the great arteries repaired with the relatively new Nikaidoh procedure show 95% late survivability rates (Martins). For truncus arteriosus, currently 83% of patients survive past 15 years (Soriano). Continuing research and refinement of existing surgical techniques are expected to increase survivorship from this congenital heart defects. To help families and patients understand that congenital condition their loved one may have, a very easy to understand picture book was created. This can hopefully inspire further improvements in family resources to aid in comprehension of congenital heart diseases.

Testo completo

Abstract (sommario):

Hospital administrators strive to reduce readmission and over use of the acute care setting for chronic health conditions. Historically hospitals have focused on readmission prevention strategies to improve the transition of patients from the hospital to the community and although the causes of a hospital readmission may span multiple providers along the continuum of care, the hospital is currently the only provider being penalized. The project facility implemented a readmission reduction strategy, Re-Engineered Discharge (Project RED), as a means to reduce readmissions and yet continued to have high readmission rates for heart failure (HF) patients. The continued high rate of readmissions led to the practice focused question, which examined the process of developing a discharge phone call script specific for HF patients as a way to reduce readmissions for HF patients. Kristin Swanson's structure of caring model provided the nursing framework for this project with a purpose to plan a telephone call follow up program for HF patients after hospital discharge. The project planning was accomplished in conjunction with the facility's readmission reduction team/LEAN team, resulting in a script about the most prevalent issues among HF patients. Kotter's 8 step change model will be used as a guide for the implementation of the telephone call follow up program at a later date. Readmission rates for HF patients will be monitored monthly as an outcome evaluation measure. Project team members provided evaluation of the project which demonstrated satisfaction and success of the planning process. The results of this project will bring about social change by providing access to healthcare providers regardless the socioeconomic status of the patient and by decreasing the use of acute care setting unnecessarily for chronic conditions.

Abstract (sommario):

Abstract Cardiovascular diseases (CVDs) are the leading cause of death in the United States. In many cases, CVDs go unnoticed or are diagnosed late, contributing to the high death rate of such diseases. To address this issue, new methods for the early diagnosis of CVDs should be developed. In many medical conditions, heart rate can play an important role as an early indicator of heart diseases. In this pilot study, a heart rate monitoring method based on cardiovascular-induced sounds is investigated. For this purpose, phonocardiography (PCG) signals are measured noninvasively on the body surface of five healthy subjects (21–24 years) using an electronic stethoscope. In addition, electrocardiography (ECG) was used as a gold-standard method of cardiac monitoring. The PCG signals were then post-processed using custom-built algorithms to estimate the subject heart rate. These estimated heart rates were then compared with the heart rate calculated from the ECG signal using the well-known Pan-Tompkins algorithm. Results showed that the heart rate estimations from the acoustic modalities were consistent with those calculated from the gold-standard ECG.

Abstract (sommario):

Review question / Objective: (1)Can heart type fatty acid binding protein effectively predict the prognosis of patients with heart failure? (2)Is high expression of ear type fat acid binding protein associated with poor clinical outcomes in patients with heart failure? Condition being studied: Heart-type fatty acid binding protein (H-FABP) mainly exists in cardiomyocytes and is a potential biomarker of myocardial injury.However, the adverse consequences of heart failure have not been fully analyzed.Therefore, the purpose of this study was to comprehensively evaluate the correlation between H-FABP and the prognosis of heart failure through meta-analysis.

Abstract (sommario):

30 Day Hospital Readmission Rates, Frequencies, and Heart Failure Classification for Patients with Heart Failure Background Congestive heart failure (CHF) is the leading cause of mortality, morbidity, and disability worldwide among patients. Both the incidence and the prevalence of heart failure are age dependent and are relatively common in individuals 40 years of age and older. CHF is one of the leading causes of inpatient hospitalization readmission in the United States, with readmission rates remaining above the 20% goal within 30 days. The Center for Medicare and Medicaid Services imposes a 3% reimbursement penalty for excessive readmissions including those who are readmitted within 30 days from prior hospitalization for heart failure. Hospitals risk losing millions of dollars due to poor performance. A reduction in CHF readmission rates not only improves healthcare system expenditures, but also patients’ mortality, morbidity, and quality of life. Purpose The purpose of this DNP project is to determine the 30-day hospital readmission rates, frequencies, and heart failure classification for patients with heart failure. Specific aims include comparing computed annual re-admission rates with national average, determine the number of multiple 30-day re-admissions, provide descriptive data for demographic variables, and correlate age and heart failure classification with the number of multiple re-admissions. Methods A retrospective chart review was used to collect hospital admission and study data. The setting occurred in an urban hospital in Memphis, TN. The study was reviewed by the UTHSC Internal Review Board and deemed exempt. The electronic medical records were queried from July 1, 2019 through December 31, 2019 for heart failure ICD-10 codes beginning with the prefix 150 and a report was generated. Data was cleaned such that each patient admitted had only one heart failure ICD-10 code. The total number of heart failure admissions was computed and compared to national average. Using age ranges 40-80, the number of patients re-admitted withing 30 days was computed and descriptive and inferential statistics were computed using Microsoft Excel and R. Results A total of 3524 patients were admitted for heart failure within the six-month time frame. Of those, 297 were re-admitted within 30 days for heart failure exacerbation (8.39%). An annual estimate was computed (16.86%), well below the national average (21%). Of those re-admitted within 30 days, 50 were re-admitted on multiple occasions sequentially, ranging from 2-8 re-admissions. The median age was 60 and 60% male. Due to the skewed distribution (most re-admitted twice), nonparametric statistics were used for correlation. While graphic display of charts suggested a trend for most multiple re-admissions due to diastolic dysfunction and least number due to systolic heart failure, there was no statistically significant correlation between age and number or multiple re-admissions (Spearman rank, p = 0.6208) or number of multiple re-admissions and heart failure classification (Kruskal Wallis, p =0.2553).
