Overview
The hallmark symptom of spontaneous coronary artery dissection (SCAD) is angina pectoris, similar to to other acute coronary syndromes, that may radiate to the jaw or left arm. SCAD should be suspected with these symptoms in relatively young women, especially those in postpartum status. However, many patients do not have typical risk factors of coronary artery disease. Patients are typically asymptomatic on follow up.
History
Patients presenting with typical symptoms of acute coronary syndromes and the following clinical characteristics may have suspected spontaneous coronary artery dissection (SCAD):
- Physical exertion[1]
- Emotional stress[2]
- Women with an average age ranging from 43 to 50 years[3][4]
- Postpartum status or history of pregnancy[5]
- History of smoking
- Atherosclerosis
- Cocaine abuse[6]
- Presence of a Connective tissue disorder: Marfan syndrome, Loeys-Dietz syndrome, Ehlers-Danlos syndrome type 4, cystic medial necrosis, alpha-1 antitrypsin deficiency, or polycystic kidney disease[7]
Many patients do not have a previous history of cardiovascular disease or other risk factors and SCAD is idopathic.[3]
Symptoms
The symptoms of SCAD mimic other acute coronary syndromes.
- The most common symptom is an acute and severe onset of chest pain that may radiate to jaw and left arm.
Patients may present with:[8]
- chronic stable angina
- myocardial infarction
- cardiogenic shock
- sudden death
- 50% of sudden death cases were reported to have dissections in the left main coronary artery.[9]
- pericardial tamponade
Patients are typically asymptomatic on follow up.[8]
