Spontaneous Coronary Artery Dissection (SCAD) is an under-diagnosed cause of acute coronary syndrome (ACS), myocardial infarction (MI) and sudden cardiac arrest. The inner lining of the coronary artery splits and allows blood to seep into the adjacent layer, forming a blockage (hematoma), or the artery continues to tear, creating a flap of tissue that blocks blood flow in the artery.
SCAD strikes generally healthy, younger individuals (average age 42) who do not have traditional cardiac risk factors. Warning signs of SCAD encompass the full range of ACS and MI symptoms, from vague to classic. The cause of SCAD is currently unknown and the psychosocial impact of SCAD is traumatizing. The work of the iSCAD Registry will encompass the physical and psychosocial study of SCAD.
