Hypertrophic cardiomyopathy is an autosomal dominant disorder caused by mutations in the gene encoding myocardial myosin, mainly manifesting as centripetal myocardial hypertrophy and small ventricular chambers; about 25% of the disease has left ventricular outflow tract obstruction, which is known as hypertrophic obstructive disease (HOCM); common symptoms include chest tightness, chest pain, shortness of breath, syncope, and vertigo, etc. Signs mainly include audible systolic ejection murmur between the 3-4 ribs at the left edge of the sternum, with increased conduction to the neck. systolic jet murmur, conduction to the neck; electrocardiogram (ECG), chest X-ray (CXR), echocardiogram (UCG) are needed to clarify the diagnosis, adding coronary angiography (CAG), magnetic resonance imaging (MRI), etc. if necessary; symptomatic, severe left ventricular outflow tract stenosis, differential pressure >= 50 mmHg at rest or >= 100 mmHg after stress should be treated surgically. Young patients with severe stenosis of the left ventricular outflow tract with a pressure difference >= 100 mmHg, or with significant mitral valve insufficiency with abnormal systolic anterior motion (SAM), such as HOCM with coronary artery bypass or valve surgery, HOCM with atrial fibrillation, where pharmacological therapy is ineffective, where septal chemical ablation has failed or where symptoms remain after pacemaker implantation, should be considered for surgery if they are not symptomatic. Patients with HOCM combined with atrial fibrillation, poor pharmacological treatment, failure of septal chemical ablation, or symptoms after pacemaker implantation should be considered for surgical treatment. The meaning of life does not lie in its dignity and toughness, but in its continuity. There is hope only if you live.
