Clinical Trial Summary

Hypertrophic cardiomyopathy (HCM) is the most common hereditary disease characterized by left ventricular hypertrophy and consequently left ventricular diastolic dysfunction. Its prevalence is estimated at around 0.2% in the general population. HCM is the most common cause of sudden cardiac death due to cardiovascular disease in young athletes, accounting for one third of deaths. HCM patients often have symptoms of heart failure. The ESC recommendations for heart failure (HF) from 2016 recommend exercise training regardless of ejection fraction to improve exercise capacity, quality of life, and reduction in hospitalizations due to HF. Meanwhile, for many years, HCM was equivalent to exercise training limitation. According to the 2014 ESC guidelines, it is recommended for patients with HCM to avoid sports practice. However the results of Edelmann et al. research, suggest that physical training leads to a significant clinical improvement in patients with diastolic dysfunction and thus may be beneficial in patients with HCM. In 2015 results of a first study were published (Klempfner et al.), which showed that the majority of HCM patients with moderate risk undergoing supervised physical training had improved physical performance and no significant adverse events were recorded. The study was limited by the small number of admitted patients (twenty), lack of control group and failure to perform cardio-pulmonary exercise test.

The main goal of the study will be to evaluate the effectiveness and safety of comprehensive cardiological rehabilitation and telerehabilitation in patients with hypertrophic cardiomyopathy without left ventricular outflow tract obstruction with preserved systolic function. The study is planned to include 30 patients with HCM subjected to physical training and 30 patients with HCM in the control group treated as standard according to current guidelines, not subjected to physical training.
