A coronary artery dissection (also known as spontaneous coronary artery dissection, or SCAD) is a rare, sometimes fatal traumatic condition, with eighty percent of cases affecting women. The coronary artery develops a tear, causing blood to flow between the layers which forces them apart.[1] Early studies of the disease placed mortality rates at around 70% but more recent data indicate this figure may be closer to 18%.[2]

Signs and symptoms
The symptoms are often very similar to those of myocardial infarction (heart attack), with the most common being persistent chest pain.[3]
Causes
SCAD
There is evidence to suggest that a major cause of spontaneous coronary artery dissection (SCAD) is related to female hormone levels, as most cases appear to arise in pre-menopausal women, although there is evidence that the condition can have various triggers. Other underlying conditions such as hypertension, recent delivery of a baby, fibromuscular dysplasia and connective-tissue disorders (e.g., Marfan syndrome and Ehlers-Danlos syndrome) may occasionally result in SCAD.[4] There is also a possibility that vigorous exercise can be a trigger. However, many cases have no obvious cause.[5][6]
Pathophysiology
Coronary artery dissection results from a tear in the inner layer of the artery, the tunica intima. This allows blood to penetrate and cause an intramural hematoma in the central layer, the tunica media, and a restriction in the size of the lumen, resulting in reduced blood flow which in turn causes myocardial infarction and can later cause sudden cardiac death.[7][8]
Diagnosis
A selective coronary angiogram is the most common method to diagnose the condition, although it is sometimes not recognised until after death.[9] Intravascular ultrasound (IVUS) is also used as it is able to more easily differentiate the condition from atherosclerotic disease.[10]
Treatment
Treatment is varied depending upon the nature of the case. In severe cases, coronary artery bypass surgery is performed to redirect blood flow around the affected area.[11] Drug-eluting stents and thrombolytic drug therapy are less invasive options for less severe cases.[10]
Epidemiology
Eighty percent of cases are in women. [12]
