Overview

The risk factors for spontaneous coronary artery dissection include predisposing factors (e.g., vasculopathy, connective tissue disorder, systemic inflammation) and precipitating stressors (e.g., strenuous exercise, emotional stress, medications).

Risk Factors

The phenotypic manifestation of spontaneous coronary artery dissection (SCAD) may occur as a result of predisposing factors compounded by precipitating stressors. The presence of either predisposing or precipitating factors increases the risk of developing a dissection. The potential risk factors include:

Risk factor	Condition
Predisposing factors	Atherosclerosis Fibromuscular dysplasia Takotsubo cardiomyopathy Pregnancy-related: antepartum, early post-partum, late post-partum, very late post-partum Recurrent pregnancies: multiparity or multigravida Connective tissue disorder: Marfan syndrome, Loeys-Dietz syndrome, Ehlers-Danlos syndrome type 4, cystic medial necrosis, alpha-1 antitrypsin deficiency, polycystic kidney disease Systemic inflammatory disease: systemic lupus erythematosus, Crohn's disease, ulcerative colitis, polyarteritis nodosa, sarcoidosis, Churg-Strauss syndrome, Wegener's granulomatosis, rheumatoid arthritis, Kawasaki disease, giant cell arteritis, celiac disease Hormonal therapy: oral contraceptive, estrogen, progesterone, beta-HCG, testosterone, corticosteroids Coronary artery spasm Idiopathic
Precipitating stressors	Intense exercises: isometric exercise, aerobic exercise Emotional stress Labor and delivery Valsava-type activities: retching, vomiting, bowel movement, coughing Recreational drugs: cocaine, amphetamines, methamphetamines Hormonal therapy: beta-HCG, corticosteroids
