The exact etiology of spontaneous coronary artery dissection remains elusive; however, fibromuscular dysplasia and takotsubo cardiomyopathy have been considered as the potential cause of spontaneous coronary artery dissection. The underlying causes associated with SCAD include emotional stress, physical stress such as extreme valsalva maneuver, retching, vomiting, coughing, isometric exercise, history of using stimulant medications or illicit drugs, pregnancy, and connective tissue disorders.


Common causes associated with spontaneous coronary artery dissection (SCAD) include:[1][2]

Fibromuscular Dysplasia

Takotsubo Cardiomyopathy (TCM)
