Women who have had multiple pregnancies have a higher risk of SCAD.Ĭonditions that affect the structure of blood vessels: There are a few inherited medical conditions that affect the structure and composition of the artery walls.
Pregnancy: SCAD is the most common cause of a heart attack in women who are pregnant or were recently pregnant. Factors that increase your risk of SCADĮven though researchers are still trying to understand exactly what causes SCAD, they have identified some risk factors for the condition:įemale sex: Somewhere between 87% to 95% of people who have SCAD are female. Researchers are still learning about the risk factors and medical problems that lead to SCAD. But no specific link between SCAD and hormonal changes has been identified.
Because it is more common in women, especially in women who are pregnant or were recently pregnant, it could be related to hormonal changes. The exact cause of SCAD is not known, but it may be related to underlying problems with the blood vessels that make them more likely to tear. It is also the most common cause of heart attacks in younger women. SCAD is an increasingly recognized and studied condition, and experts now estimate it is responsible for 1 to 4% of all heart attacks. What causes spontaneous coronary artery dissection? In this article, we review what causes SCAD, who is at increased risk, the most common symptoms, and treatment. And this can occur in people without typical risk factors. In a spontaneous coronary artery dissection (SCAD), the blockage occurs because there is a tear in the artery, which leads to a buildup of blood in the blood vessel wall. Most commonly, this blockage is caused by atherosclerosis, or plaque in the artery wall. This occurs when there is a blockage in the coronary arteries, the blood vessels that supply oxygenated blood to the heart. A heart attack (myocardial infarction) happens when there is not enough blood flow to the heart muscle.
