Causes of sudden cardiac death

The causes of sudden cardiac death include congenital coronary artery abnormalities, hypertrophic cardiomyopathy, coronary atherosclerotic heart disease, etc.

1. Congenital coronary artery abnormalities

If the patient has congenital coronary artery abnormalities, the coronary artery may contract during strenuous exercise, leading to cardiac ischemia, resulting in sudden cardiac death.

2. Hypertrophic cardiomyopathy

Hypertrophic cardiomyopathy can lead to left ventricular diastolic disorders, left ventricular blood filling obstruction, easy to cause heart failure, and then cause sudden cardiac death.

3. Coronary atherosclerotic heart disease

Coronary atherosclerotic heart disease is easy to cause myocardial infarction, and then the heart, brain ischemia, causing sudden cardiac death.
