Sahlgrenska Cardiomyopathy Project
Dilated CardiomyopathiesHypertrophic Cardiomyopathy6 moreThis is a joint project by Sahlgrenska University Hospital: Sahlgrenska, Östra and Mölndal. Our objective is to diagnose and map patients with well phenotyped cardiomyopathies (CMP) including in depth clinical and molecular phenotyping to enable earlier and specific treatment. The project will serve as: resource for diagnostic and therapeutic trials common biomaterial bank resource for detailed molecular analyses on patients' biomaterials and patient specific symptoms and examination results
The Chinese Hypertrophic Cardiomyopathy Study(CHCS)
CardiomyopathyHypertrophicHypertrophic cardiomyopathy (HCM) is one of the most common inherited cardiac diseases, with a prevalence of ∼0.2%. Sudden cardiac death (SCD), heart failure and stroke are the major poor outcomes of HCM. Although about half of the patients were found to be caused by mutations mainly located in genes encoding sarcomere proteins, the causes in a significant proportion of patients with HCM are still unknown. Even in the patients with sarcomere mutations, the molecular pathways that eventually lead to cardiac hypertrophy are remained to be revealed. Furthermore, HCM presents with significant heterogeneity. SCD risk stratification and prevention by ICD are necessary. However, the strategy of SCD risk stratification recommended by the 2011 ACCF/AHA and 2014 ESC guidelines were based mainly on the evidence derived from American and European countries. The accuracy of these guidelines in Chines patients with HCM was not evaluated yet.
Intraventricular Stasis In Cardiovascular Disease
Dilated CardiomyopathyThrombosis Cardiac2 moreThis 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.
Egyptian Hypertrophic Cardiomyopathy Program
Hypertrophic CardiomyopathyEgyptian 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.
A Noninterventional, Single-Center Feasibility Study to Evaluate Measures of Heart Failure Risk...
Heart FailureCardiomyopathy2 moreThis 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.
Exercise Oxygen Kinetic and Cardiac Output in Hypertrophic Cardiomyopathy
Cardiopulmonary Exercise TestHypertrophic Cardiomyopathy1 moreFatigue 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.
Observational Study for Patients With Hypertrophic Cardiomyopathy
HCM - Hypertrophic CardiomyopathyObservational 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.
French Hypertrophic Cardiomyopathy Observatory
Hypertrophic CardiomyopathyHypertrophic 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)
A Prospective Incident Study of Arrhythmias in Hypertrophic Cardiomyopathy
Hypertrophic CardiomyopathyThe 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.
Association of Obesity and Cardiovascular Outcomes in Hypertrophic Cardiomyopathy
ObesityHypertrophic Cardiomyopathy1 moreIn this study, the investigators evaluated the association between various measures of adiposity [BMI and waist circumference (WC)] and clinical outcomes in Asian patients with hypertrophic cardiomyopathy, using a nationwide population based cohort.
