What is SCAD?

Spontaneous Coronary Artery Dissection (SCAD) is an uncommon emergency heart condition that occurs when a tear forms in one of the blood vessels in the heart. SCAD can slow or block blood flow to the heart, causing a heart attack, abnormalities in heart rhythm or sudden death. SCADs typically occur in people with no standard risk factors for heart attack & while the Mayo Clinic SCAD study has identified some associated conditions, the underlying cause of SCAD is unknown in most patients.
