Active clinical trials for "Ventricular Remodeling"

This study aim to investigate the predictive value of CMR parameters: infarct size (IS), intramyocardial hemorrhage, microvascular obstruction, area at risk and CMR derived strain parameters with the Major Adverse Cardiovascular Events (MACEs) and myocardial remodeling afterinfarction.

The uncertainty concerning the onset and the extent of cardiac remodeling in response to intensive training hinders medical evaluation by physician. A better knowledge of the physiology of cardiac adaptation to training will enable physicians to correctly determine whether observed patterns of cardiac remodeling are physiological or pathological. This prospective study proposes to assess in a trained-athlete population the cardiac remodeling in response to intensive exercise training. This study is observational, we do not interfere with athlete's training.

The study intends to investigate the alteration of regional myocardial work in patients with acute anterior myocardial infarction underwent primary percutaneous coronary intervention (PCI), and compare the distribution of regional myocardial work in patients with/without early remodeling at acute phase and 3-month follow-up.

This study investigates damage of the right cardiac chamber in adult patients with a congenital heart defect involving the pulmonary valve (the heart valve between the right cardiac chamber and the lungs). The investigators want to investigate if novel, less invasive techniques are feasible to assess damage of this right cardiac chamber, to improve follow-up and timing of intervention (valve replacement) in this group of patients.

This study aims to determine whether thyroid hormone levels are predictive of cardiac remodeling following myocardial infarction and the prognosis in patients with STEMI receiving primary percutaneous coronary intervention.

Background: Sacubitril/valsartan, a novel therapy in the treatment of heart failure with reduced ejection fraction (HFrEF), has recently proved efficacy in improving exercise tolerance and cardiac performance. Cardiopulmonary exercise test (CPET) provides functional prognostic parameters for patient with HFrEF (i.e. peakVO2 and ventilation/CO2 production [VE/VCO2] slope) and it is a well-recognized, valuable, accurate tool for risk stratification. Aim of the study and methods: The aim of the study is to prospectively enroll a cohort of 100 HFrEF outpatients eligible for sacubitril/valsartan and perform serial CPET, laboratory and echocardiographic assessments before and during the gradual titration of the treatment, in order to evaluate its effects on cardiopulmonary function and left ventricular remodeling. The procedures will be repeated along the follow-up at 1, 2 and 3 months after the enrollment (titration period) and at 6 months after the reach of the maximum tolerated dose.

failure of closure of the ductus arteriosus after birth results in a congenital anomaly known as patent ductus arteriosus. The large ductus can induce left side heart remodeling changes which could interfere with the normal cardiac function.

Right ventricular (RV) physiological remodeling in response to prolonged strength exercise remains poorly studied. This prospective, non-randomized, single-center study, proposes to follow 24 healthy sedentary volunteers who will benefit from a high-intensity pure resistance training program over a 6-month period. The volunteers, aged between 18 and 40 years old and male, will be recruited and evaluated at the University Hospital center of Caen Normandy. Cardiac remodeling in response to physical exercise will be analyzed by trans-thoracic echocardiography repeated during the follow-up. The physical impact of the training program will be assessed by a treadmill exercise test predicting maximal oxygen consumption (VO2max) before and after completing the training, and an isokinetic muscular test repeated every 3 months. Participants rest/activity cycles will be monitor before and after 3 months of training. The aim of the study is to demonstrate the existence of a physiologic RV remodeling in response to pure high-load resistance chronic exercise. The results will help to improve the understanding of the physiological RV response expected in strength athletes.

This project focuses on the physiopathology of left ventricular remodeling associated with type II diabetes in patients with aortic valve stenosis referred for surgical aortic valve replacement. The main objective is to compare the reverse left ventricular remodeling between patients with type II diabetes and case-control patients without diabetes at one(1) year after surgical aortic valve replacement. The secondary objectives are : assess the influence of type II diabetes on left ventricular remodeling in patients presenting with aortic valve stenosis, assess the predictive value of myocardial fibrosis and other LV characteristics present prior to aortic valve surgery on the LV reverse remodeling and their influence on cardiovascular events at one (1) year after surgery, assess the influence of type II diabetes on cardiovascular morbidity and mortality post aortic valve surgery. The investigators main hypothesis is that patients with type II diabetes and aortic valve stenosis requiring aortic valve replacement have poorer LV function and less favorable post surgery clinical outcomes than patients without type II diabetes.

To detect long-term effects of left ventricular remodeling in STEMI patients undergoing PPCI. And to evaluate outcome.
