WebMar 6, 2024 · Thin filament hypertrophic cardiomyopathy (HCM) mutations increase myofilament Ca 2+ sensitivity and alter Ca 2+ handling and buffering. The myosin inhibitor mavacamten reverses the increased contractility caused by HCM thick filament mutations, and we here test its effect on HCM thin filament mutations where the mode of action is … WebPATIENTS AND METHODS: Comprehensive mutation analysis of the 8 HCM susceptibility genes that encode the myofilaments of the cardiac sarcomere was performed previously in 382 unrelated patients with HCM. Blinded to genotype status, we used echocardiography to characterize the left ventricular morphological features.
