Filter by:To demonstrate the efficacy of ranolazine in improving coronary microvascular and diastolic dysfunction in patients affected by HCM evaluating changes in maximum (i.e. during dipyridamole-induced coronary vasodilatation) myocardial blood flow (MBF) measured by PET at baseline and after 4 months of treatment with ranolazine in patients with non obstructive HCM.
Objective of the study: to evaluate whether alfieri technique improves clinical and hemodynamic results compared to transaortic mitral valve secondary cord cutting in patients scheduled to septal myectomy for severely symptomatic hypertrophic obstructive cardiomyopathy.
The purpose of the study is to assess the role of mitral valve apparatus in the development of outflow tract obstruction in patients with hypertrophic cardiomyopathy and to identify the best surgical treatment modality to relieve outflow tract obstruction in such patients
The main objective of the study is to improve implantable cardioverter defibrillator (ICD) implantation decision-making processing relevance by developing a new prediction model of sudden cardiac death (SCD) in hypertrophic cardiomyopathy (HCM), including newly identified potential biomarkers by magnetic resonance imaging (MRI) and genetics, through a prospective nationwide study, multivariate analysis and modelling of an absolute risk. The secondary objective is to perform a medico-economic analysis of ICD implantation in order to define an optimal rule for ICD implantation in patients with HCM, taking into account the benefits of ICD, adverse effects of ICD and associated costs (cost of quality adjusted life years saved).
The overall aim of this project is to establish potential benefits of a novel lifestyle (physical activity and dietary nitrate) and pharmacological (angiotensin receptor neprilysin inhibitor) interventions in patients with hypertrophic cardiomyopathy (HCM). HCM is the most common genetic cardiovascular disease with a broad spectrum of disease severity. Angiotensin receptor neprilysin inhibitor reduces death, hospitalisation, and may improve cardiac function and exercise tolerance in heart failure. Exercise training is associated with a significant increase in exercise tolerance, but appear to have limited effect on measures of cardiac morphology or function in patients with HCM. Dietary supplementation with inorganic nitrate (i.e. concentrated nitrate-rich beetroot juice) improves exercise capacity, vasodilatation and cardiac output reserves while reduces arterial wave reflections, which are linked to left ventricular diastolic dysfunction and remodelling. Using a five-centre, open label, three-arm, pilot design, the present study will evaluate the effect of lifestyle (physical activity and dietary supplementation with inorganic nitrate) and pharmacological (angiotensin receptor neprilysin inhibitor sacubitril / valsartan) interventions in patients with HCM. The Aim is to examine whether these interventions improve functional capacity, clinical phenotypic characteristics, and quality of life in patients with HCM.
The purposes of this study are to: 1. Learn about the safety of CK-3773274 after a single dose and multiple doses in healthy subjects. 2. Learn how healthy subjects tolerate CK-3773274 after a single dose and multiple doses. 3. Find out how much CK-3773274 is in the blood after a single dose and multiple doses. 4. Determine the effect of doses of CK-3773274 on the pumping function of the heart. 5. Evaluate the effect of cytochrome genetic variants on how the body metabolizes CK-3773274. 6. Evaluate the effect of a meal on how much CK-3773274 is in the blood in healthy adult subjects. 7. Evaluate whether the amount of CK-3773274 in the blood is the similar for both the tablet and granules in capsule forms of the drug.
This is a prospective, single-center study to assess clinical phenotype and prognosis of different pathogenic mutations in Chinese patients with hypertrophic cardiomyopathy. Patients with hypertrophic cardiomyopathy were consecutively recruited, and then DNA samples were extracted from peripheral blood. Targeted sequencing of 142 genes was performed to obtain variants associated with hypertrophic cardiomyopathy. Patients will undergo face-to-face interviews, phone calls, or/and chart reviews at 6 months, 12 months, 24 months, 36 months, 48 months and 60 months for data collection of clinical outcomes.
Approximately 30 sites that enrolled participants in the MAVERICK-HCM (MYK-461-006) study in the United States (US) will initiate this study. Approximately 90 sites that enrolled participants in the EXPLORER-HCM (MYK-461-005) study in the US, Europe, and Israel will initiate this study. Note: Approximately 30 centers overlap between MAVERICK and EXPLORER.
A Study to evaluate the efficacy of psychotherapy for easing the cardiac symptoms and improving and quality of life in patients with hypertrophic cardiomyopathy accompanied with depression
Scanning the heart using magnetic resonance imaging (MRI) enables detailed assessment of its structure and function. MRI can give more detailed information about the heart by using a contrast 'dye' that is injected into a vein during the scan. This can highlight abnormal areas within the heart. Current contrast dyes help identify scarring within the heart, which is useful in people who have had heart attacks. The investigators plan to test new contrast dye containing manganese, which works differently to current agents. They believe it will provide unique insight into how the heart works. There are many different causes of heart problems and the investigators plan to use this new contrast agent to scan three patient groups; (i) heart disease caused by heart attacks, (ii) heart disease with abnormal thickening of the heart muscle, and (iii) heart disease where the heart becomes stretched and enlarged. Healthy volunteers will be scanned for comparison. The study will be carried out at the Royal Infirmary of Edinburgh. Adults between 18 and 65 with stable heart failure can be considered. Women who may be pregnant are unable to participate, as is anyone who has some types of metal in their body, as these people can't have an MRI scan safely. All participants will have 2 MRI scans lasting about an hour each, at least 2 days apart. Some participants will be have 4 MRI scans, over a longer time period. The investigators will also take some blood samples and record a tracing of the heart rhythm and will ensure there are no abnormal side-effects by telephone follow up. The investigators believe this new agent has potential to better measure disease in the heart, improve the ability to establish the cause of heart disease and help monitor the disease over time as well as guide future treatment for individual patients.
