Phase I-II Clinical Trial-Safety and efficacy of umbilical cord derived mesenchymal stem cells (UC-MSCs) in patients with chronic heart ischemia cohort and perspective study.
The purpose of this study is to determine if detailed scanning of the heart before biventricular device insertion will improve outcomes for heart failure patients.
The purpose of this study is to observe the evolution of the CRTD system with left quadripolar lead, in terms of electrical parameters in all pacing configurations and to evaluate the impact on the clinical outcome.
Growing recognition of the importance of co-morbidities in Heart Failure with Preserved Ejection Fraction (HFPEF) has led to the realization that rather than being a distinct disease entity, HFPEF may represent a spectrum of co-morbidities in elderly breathless patients. Accordingly, progress in managing HFPEF in the elderly requires improved understanding of HFPEF pathogenesis with a focus on the impact of co-morbidities. However, the available evidence is insufficient to determine the true prevalence and severity of co-morbidities as well as their impact on both diagnosis and treatment in HFPEF. Therefore there are widespread diagnostic uncertainty without proven therapy! The purpose of this project is twofold: 1. The investigators will study how to improve diagnostic accuracy for HFPEF in elderly patients, despite frequent comorbidities and higher age? How useful is it to add exercise testing and contrast echocardiography as well as biomarker as additional diagnostic tools in elderly HFPEF patients? 2. The investigators will test the hypothesis that HFPEF in the elderly is dominated by multiple co-morbidities that are a major part of the syndrome itself that contribute to the development of HFPEF. This hypothesis implies that the treatment of co-morbidities will improve prognosis. The investigators' overall goal is to bring about a paradigm shift in managing elderly patients with HFPEF by not only improving diagnosis but also effectively treating co-morbidities that are currently considered predisposing factors to HFPEF. This contrasts with trials during last two decades that only target the heart. The investigators will pursue the following specific aims: 1. Validate the diagnostic criteria for HFPEF proposed by European Society of Cardiology 2012, and determine the added diagnostic values of exercise testing and contrast echocardiography as well as biomarker for HFPEF in a multi-center study. 2. Determine if systematic screening and optimal management of co-morbidities associated with HFPEF improves the outcomes of patients with HFPEF in a randomized study.
Heart failure (HF) is a serious chronic disease with frequent readmissions, some of which can be prevented by early action. The management of HF is complex: long, often difficult and costly. In France, nearly one million people suffer from HF and 120,000 new cases are diagnosed every year. With the aging population, this number will continue to evolve and become a real public health problem. Within 10 to 20 years ahead, WHO projects that heart failure in either the 3 most common diseases in industrialized countries. The objective of the project is to test an intelligent platform for monitoring at home, using non-intrusive sensors, patients with heart failure, particularly those with stage II and III NYHA. It will assist the medical automating the processing of information from these sensors to detect and report an early stage risk situations. Patient monitoring, by a system of telemedicine tools associated with motivation and education helps significantly reduce the number of days of hospitalization becomes important when the patient is hospitalized for acute HF.
Cohort study aimed at evaluating the incidence of left ventricular (LV) dysfunction after myocardial infraction (MI) and assessing the prognostic utility of change in ejection fraction (EF) over the initial 12 months after MI.
The purpose of this study is to evaluate the effect of Cardiac Sympathetic Blockade on Mortality, re-hospitalization rate, symptoms, quality of life, exercise tolerance, cardiac structure, systolic function, electrical activities and concentration of B - type natriuretic peptide precursor in patients with Chronic Heart Failure.
The purpose of this project is to evaluate the utility of left ventricular strain as part of the assessment of patients in the emergency department with acute heart failure (HF). The central hypothesis of the investigation is that left ventricular strain will prove to be a treatment response variable in patients with acute HF. Patients who are being treated for acute HF with intravenous (IV) vasoactive medications (diuretics, vasodilators, inotropes) will be eligible for enrollment. Patients who give written consent will receive a focused bedside echocardiogram within 30 minutes of the initiation of therapy for acute HF. Images that are captured during this echocardiogram will be interpreted by a blinded cardiologist offline. 23 hours after this initial focused echocardiogram a member of the study team will perform a follow-up focused echocardiogram, capturing the same images that will then be interpreted by a blinded cardiologist offline. Offline analysis will be performed using a proprietary software package from General Electric called Automated Function Imaging (AFI). The AFI software will be used to calculate longitudinal strain of the left ventricle (LV). Regional and global strain values will be calculated for each focused echocardiogram for each subject. It is our hypothesis that LV strain will demonstrate improvements from the initial echocardiogram to the follow-up echocardiogram, unlike other echocardiographic indices in HF such as LV ejection fraction.
This is a single-center, non-randomized study.The study staff will use the InSpectraTM tissue oxygen saturation (StO2) monitor manufactured by Hutchinson Technology to measure baseline StO2 levels after applying the noninvasive probe to the thenar eminence. After a stable reading is obtained, a blood pressure cuff will be inflated 40 mmHg above the obtained systolic pressure and the rate of desaturation (Rdes; % × sec-1) will be recorded. After 3 minutes or once the StO2 level comes to zero (whichever is earlier), the cuff pressure will be released and the rate of reperfusion (Rres; % × sec-1) will be measured. The investigators hypothesize that heart failure in children causes a baseline lower thenar tissue oxygen saturation (StO2), a faster rate of desaturation (Rdes) and a prolonged rate of reperfusion (Rres). The investigators also hypothesize that these changes will correlate with the severity of heart failure. The results of this study will provide groundwork for studies looking at correlation of therapy modification based on the combination thenar StO2 and clinical presentation.
