The treatment of hypertrophic cardiomyopathy aims to improve symptoms, reduce complications, and prevent sudden death. The methods include improving ventricular compliance by reducing outflow tract obstruction, preventing thromboembolic events, and identifying high-risk patients for sudden death. Treatment needs to be individualized, and the main treatments include the following aspects: 1. Medication treatment. Drug treatment is fundamental, and drugs targeting outflow tract obstruction mainly include receptor blockers and non-dihydropyridine calcium channel blockers. For patients with congestive heart failure, targeted treatment is required. Anticoagulation treatment is necessary for patients with atrial fibrillation, and it is worth noting that for patients with chest discomfort, care should be taken to exclude outflow tract obstruction when using nitrate drugs to avoid exacerbation after use. Non-drug treatments include: 1. Surgical treatment: For patients with ineffective drug treatment and heart function class three to four, if there is severe outflow tract obstruction, septal myectomy should be considered. Currently, surgery is listed as the preferred treatment for suitable patients in consensus guidelines in both America and Europe. 2. Alcohol septal ablation; 3. Pacing therapy.
