What is spontaneous coronary artery<br />
dissection (SCAD)?<br />
<strong>Spontaneous</strong> coronary artery dissection (SCAD), is when there is a sudden tear in the wall<br />
of one or more blood vessels in the heart. This results in a buildup of blood between the<br />
layers of the artery wall. As blood collects between the layers of the wall, the vessel<br />
narrows. This impairs blood flow to the heart which causes a heart attack.<br />
