This systematic review and meta-analysis evaluated the effects of structured and habitual exercise on cardiac remodeling and safety in individuals with hypertrophic cardiomyopathy (HCM). Analyzing data from 11 studies with 1457 participants, the findings indicate that exercise does not lead to adverse changes in cardiac structure or increased arrhythmic risk, supporting its safety in this population.
Key findings
- Exercise did not result in adverse changes in wall thickness, chamber volumes, or left ventricular ejection fraction.
- No excess adverse events, including sudden cardiac death or ventricular arrhythmias, were reported.
- VO2 peak changes were heterogeneous, indicating individualized functional improvement in some trials.
Why it matters
The findings challenge traditional exercise restrictions in HCM patients, suggesting that structured exercise may be safe and beneficial. This could influence clinical recommendations and patient management strategies, promoting a more active lifestyle for affected individuals.
