Hypertrophic cardiomyopathy (HCM) is a genetic heart condition characterized by the thickening of the heart muscle, particularly affecting the left ventricle. This abnormal growth can obstruct blood flow, leading to symptoms such as shortness of breath, chest pain, and fatigue, and it may increase the risk of serious complications like arrhythmias and sudden cardiac arrest. Advances in hypertrophic cardiomyopathy medicine have significantly improved diagnosis and management, with tools such as echocardiography and genetic testing aiding in early detection. Treatment options include lifestyle modifications, medications to manage symptoms and reduce the risk of complications, and in some cases, surgical interventions such as myectomy or alcohol septal ablation. Ongoing research continues to explore novel therapies and approaches aimed at enhancing patient outcomes, ultimately providing hope for individuals living with this complex condition.
