In this paper, 44 patients diagnosed with hypertrophic cardiomyopathy by cardiovascular angiography were analyzed. The results showed that: (1) The main symptoms were exertional dyspnea, precordial pain and syncope; the typical signs were systolic murmur of the left sternal border (ejection, first and third intercostal space), excitation Amyl ester inhalation) increased; green, middle-aged good hair, there are unknown causes of syncope and positive family history. ② ECG is characterized by left ventricular hypertrophy, abnormal Q wave and V_1 lead high narrow R wave. ③ echocardiography is characterized by IVS / LVPW ≥ 1.3, left ventricular outflow tract ≤ 20mm and the aortic valve clearly shows contraction with mid-term closure, it is recommended less
