What is acute coronary insufficiency?

Acute coronary insufficiency refers to a sudden reduction in blood flow to the heart muscle, often due to a blockage in the coronary arteries. This condition can lead to angina (chest pain) or myocardial infarction (heart attack) if not promptly treated. It is typically caused by atherosclerosis, where plaque buildup narrows the arteries, or by other factors like blood clots. Immediate medical attention is crucial to restore blood flow and minimize heart damage.
