Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
At baseline (visit 1, V1) and after 6 weeks of exercise intervention (visit 2, V2) all patients undergo a medical exam, resting and stress echocardiography and receive a questionnaire on the quality of life (Kansas City Cardiomyopathy Questionnaire). Cardiac biomarkers are assessed. 3 hours after stress echocardiography cardiopulmonary exercise testing is performed to measure peak oxygen consumption (VO2peak).
The primary outcome is safety. Secondary outcomes include the change of VO2peak, changes in cardiac biomarkers, resting and stress echocardiographic variables, quality of life and variables of cardiopulmonary exercise testing from V1 to V2.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Patients previously treated with transcoronary septal ablation or surgical myectomy, more than low grade valve pathology during resting echocardiography, syncope or sustained ventricular tachycardia within 6 months prior to study inclusion, prior implantable cardioverter defibrillator implantation, persistent or permanent atrial fibrillation (AF) without anticoagulation for ≥4 weeks or paroxysmal or intermittent AF on screening electrocardiogram, or a corrected QT-interval (Fridericia-formula) ≥ 500 ms will be excluded. Patients with a Sudden Cardiac Death Risk Score ≥4% are excluded from the study.
Due to the rare nature of the disease and the large geographical variation, patients within 1 hour of travel to the training site will join IT, patients travelling more than 1 hour will be grouped into UC.
At baseline (visit 1, V1) and after 6 weeks of exercise intervention (visit 2, V2) all patients undergo a medical exam, resting and stress echocardiography and receive a questionnaire on the quality of life (Kansas City Cardiomyopathy Questionnaire). Cardiac biomarkers are assessed. 3 hours after stress echocardiography cardiopulmonary exercise testing (CPET) is performed to measure peak oxygen consumption (VO2peak).
The primary outcome is safety (no ventricular arrhythmias during exercise intervention or within 1 hour after completion of exercise). Secondary outcomes include changes in VO2peak, changes in cardiac biomarkers, resting and stress echocardiographic variables, quality of life and CPET variables. Physicians performing the echocardiographies and CPET analyses will be blinded to group allocation.
