Causes of acute left heart failure

Acute left heart failure is considered to be caused by factors such as acute myocardial disease, acute abnormal cardiac load, acute arrhythmia, etc.

1.

Acute myocardial infarction occurs in patients with acute myocardial disease due to drugs, alcohol, microbial infection and other factors, and myocardial contractility is weakened, resulting in acute left heart failure.

2. Acute abnormal cardiac load

patients cause acute left heart failure due to hypertension, aortic valve stenosis, pulmonary hypertension, pulmonary valve stenosis and other factors, resulting in a sharp increase in cardiac load, affecting cardiac ejection function.

3. Acute arrhythmia

patients cause acute left ventricular filling due to acute atrial fibrillation, ventricular arrhythmia, atrial tachycardia and other factors, resulting in acute left ventricular failure.
