Active clinical trials for "Hypertrophy"

This study is designed to quantify the ventricular stasis in patients with different forms of cardiomyopathy and at risk of stroke (ischemic, non-ischemic dilated cardiomyopathy and hypertrophic cardiomyopathy) by post-processing of 2D color Doppler echocardiography and phase contrast-magnetic resonance images in order to establish the relationship between quantitative variables of intraventricular stasis and the prevalence of silent embolic events and/or intraventricular mural thrombosis.

The study aims to test the diagnostic accuracy of native T1 mapping for the diagnosis of cardiac amyloidosis prospectively. The hypothesis is that native T1 mapping with a cut-off value of 1341ms (3 tesla CMR) in older patients with symptomatic heart failure, increased LV wall thickness and elevated cardiac biomarkers is non-inferior to the reference method to diagnose cardiac amyloidosis (CA). As secondary measure, a web-based ATTR probability estimator for the diagnosis of CA will be evaluated.

Egyptian HCM program aims at defining incidence, severity, phenotype, genotype and determinants of the disease in Egypt, and providing state-of-the-art treatment strategies including medical, surgical and interventional procedures which are patient- and disease-specific.

This is a non-invasive/observational study in healthy and mild HF subjects utilizing clinical and ambulatory measurements to improve detection, monitoring, and management of HF risks.

Pyloric stenosis is a current condition in pediatric surgery. The medical management prior to surgery consists of ionic correction. The nasogastric tube is commonly used to prevent gastric fluid inhalation before surgery, but there is no study on it benefits in this specific use. Other studies suggest that utilization of a gastric tube in pyloric stenosis may increase the duration of the medical treatment. The aim of the study is to evaluate the benefit of the nasogastric tube to prevent respiratory complications. This retrospective, monocentric and descriptive study include all patients hospitalized for pyloric stenosis in the university hospital in Amiens between 2014 and 2021. Patients with and without nasogastric tube prior to surgery are compared, regarding respiratory complications define as use of antibiotic, or oxygen therapy or infection in the lungs X-ray before surgery. The investigators analyze pre-operative data: vomiting, dehydration, time to ionic disorders correction and pain, and also notice the length of hospital stay. Data during hospitalization are analyzed and will be noticed the last medical contact represent by the post-operative consultation.

Fatigue and dyspnea that reduce exercise performance are common symptoms in patients with hypertrophic cardiomyopathy. Since the cause of this functional limitation has not yet been described, this study aims to evaluate the cardiopulmonary parameters measured at cardiopulmonary exercise test in combination with those obtained by non-invasive measurement of cardiac output by impedance (Physioflow) and echocardiography. These results will help to better define the mechanisms underlying limitation in these patients, also in relation to the degree of LVOT obstruction. The aim of the present study is to assess the cardiopulmonary response to exercise in patients with hypertrophic cardiomyopathy, based on the degree of LVOT obstruction, by adding non-invasive measurement of cardiac output by Physioflow and echocardiographic parameters to the cardiopulmonary exercise test parameters associated with stroke volume and cardiac output (ie. VO2/WR, O2pulse) Consecutive patients with a previous diagnosis of hypertrophic cardiomyopathy on optimised medical therapy will be enrolled to perform a cardiopulmonary exercise test with simultaneous measurement of cardiac output and an exercise echocardiogram for clinical routine.

CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.

Observational study on patients with hypertrophic cardiomyopathy aims to investigate the correlation between cardiac fibrosis, as indicated by cardiac magnetic resonance, and the prognosis, and further to explore biomarkers for cardiac fibrosis and adverse prognosis of hypertrophic cardiomyopathy. Therefore, endpoints including all-cause mortality, cardiovascular death, ventricular arrythmia, non-fatal stroke, non-fatal myocardial infarction, sudden death, successful cardiopulmonary resuscitation will be evaluated.

Hypertrophic cardiomyopathy (Hypertrophic CardioMyopathy=HCM) remains a poorly understood disease with an assumption insufficiently codified. There is no data available in France on the profile of patients, diagnostic methods and assessment and therapeutic use. The purpose of this study is to establish a monitoring of patients with HCM (sarcomere of origin or not) in France (diagnosis, treatment)

The purpose of this research study is to understand more about various heart rhythms (electrical problems) in persons with hypertrophic cardiomyopathy with and without sleep apnea.
