Will Elevated Left Ventricle Filling Pressures Decrease by a Group

Status Completed

Clinical Trial Summary

Aims and objectives: The primary objective of this study is to assess whether a structured exercise program improves cardiac relaxing properties in patients with hypertrophic cardiomyopathy (HCM). Background: HCM is a hereditary disease in which the myocardium becomes thickened without an identifiable cause (other than genetic). It is the most common genetic cardiovascular disease with an estimated prevalence of 1/500 (i.e. 10.000 affected individuals in Denmark). The majority of patients with HCM suffers from shortness of breath and reduced exercise capacity due to increased left ventricular (LV) stiffness. Exercise training has been shown to improve exercise capacity and symptoms in patients with HCM, but the mechanisms responsible for this improvement are not known. Methods and materials: The study is a randomized, single blinded, prospective, controlled clinical trial. Eighty patients are recruited from outpatient clinics in the Capital Region of Denmark. Patients are randomized in a 1:1 ratio to 12 week of moderate-intensity exercise training or usual activity level. Assessments will include right heart catheterization, echocardiography, cardiopulmonary exercise testing, blood-samples, quality of life, and, in a subgroup of patients, cardiac magnetic resonance imaging. The primary end-point is change in LV filling pressure assessed as pulmonary capillary wedge pressure at 25 W workload. Expected outcome and perspectives: The investigators hypothesize that an exercise training program will reduce cardiac stiffness and improve symptoms in patients with HCM. Training of HCM patients has long been debated and the topic is poorly researched. The effects of exercise on hemodynamics in HCM patients are unknown and a better understanding of these mechanisms is pivotal for improving treatment.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
