Causes of cardiogenic syncope

The occurrence of cardiogenic syncope may be related to myocarditis, congenital heart disease, coronary atherosclerotic heart disease, etc.

1.

Infection with pathogenic bacteria such as myocarditis virus, bacteria, and fungi may cause myocarditis. Patients with this disease may develop cardiogenic syncope due to decreased myocardial contractility, resulting in reduced cardiac output, which may be accompanied by arrhythmia or atrioventricular block.

2.

Abnormal development of the heart or arterial blood vessels during embryonic development of congenital heart disease may lead to this disease. Patients with congenital heart disease may cause pulmonary hypertension, which may cause the above symptoms.

3. Coronary atherosclerotic heart disease The

accumulation of plaque on the coronary artery wall may cause coronary atherosclerotic heart disease. Patients with this disease may also cause cardiogenic syncope due to insufficient blood supply to the myocardium.
