The direct cause of cardiac arrest

The direct causes of cardiac arrest include heart disease, macrovascular disease, respiratory tract diseases, etc.

1. Cardiac diseases such

as acute myocarditis, coronary atherosclerotic heart disease, aortic valve stenosis, idiopathic hypertrophic aortic valve stenosis, primary dilated cardiomyopathy, Keshan disease, pulmonary stenosis and Fallot's tetralogy may cause cardiac arrest.

2. Macrovascular diseases

include aortic dissection, pulmonary embolism, coronary aneurysm, aortic aneurysm rupture, cerebral hemorrhage, massive hemorrhage of digestive tract, etc., which may also induce cardiac arrest.

3. Respiratory tract diseases

such as respiratory tract inhalation of foreign bodies, persistent asthma attack, laryngeal spasm, acute respiratory paralysis, etc. can cause respiratory difficulties and lead to myocardial hypoxia induced cardiac arrest.
