There are several types of coronary heart disease

Coronary heart disease is classified according to the disease onset characteristics and treatment principles. It can be generally divided into two categories: chronic coronary disease and acute coronary syndrome.

1. Chronic coronary disease: including stable angina pectoris, ischemic cardiomyopathy and latent coronary heart disease.

2. Acute coronary syndrome: including unstable angina pectoris, ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, etc.

Coronary heart disease is mainly caused by the accumulation of plaques on the coronary artery wall. Coronary artery stenosis causes myocardial ischemia and hypoxia. Patients need to follow the doctor's advice to use nitrates, beta receptor antagonists, calcium channel blockers and other drugs to improve myocardial ischemia.
