Overview
Spontaneous coronary artery dissection is an emergency condition that occurs when a tear forms in a wall of a heart artery. Spontaneous coronary artery dissection also is called SCAD.
SCAD can slow or block blood flow to the heart, causing a heart attack, heart rhythm problems or sudden death.
SCAD most commonly affects women in their 40s and 50s, though it can occur at any age and can occur in men. People who have SCAD often don’t have risk factors for heart disease, such as high blood pressure, high cholesterol or diabetes.
SCAD can cause sudden death if it isn’t treated promptly. Get emergency medical help if you have heart attack symptoms — even if you think you aren’t at risk of a heart attack.

When to see a doctor
