Spontaneous multivessel coronary artery dissection: repeated presentation in a healthy postmenopausal woman

Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction which is infrequently diagnosed antemortem. Most previously reported cases were found in women of whom a significant proportion presented during pregnancy or the postpartum period. We describe the first antemortem case of spontaneous coronary artery dissection, unrelated to pregnancy or the postpartum state, which ultimately resulted in diffuse involvement of both the left and right coronary arteries over a period of 4 months. Pathophysiology and case management of this disorder are discussed.
