title: Variations in Clinical Presentation, Risk Factors, Treatment, and Prognosis of Spontaneous Coronary Artery Dissection.
abstract: Spontaneous coronary artery dissection (SCAD) has been considered a rare cause of acute coronary syndrome (ACS) in younger patients without known cardiovascular risk factors. However, recent studies have reported a higher incidence of SCAD in patients presenting with ACS with use of advanced invasive imaging modalities. In light of increasing awareness, the diagnosis of SCAD has increased significantly. We conducted a single-center retrospective analysis of cases with reported SCAD during a 10-year period between 2003 and 2013. Ten cases of SCAD were identified after review of coronary angiograms and clinical records. Basic demographic details, comorbidities, initial presentation, length of dissection, specific vessels involved in dissection, initial management, subsequent outcome, and incidence of recurrence were documented. All patients were female, with mean age of 42 years. One-third of cases occurred in the peripartum period. All patients presented with acute coronary syndromes. The left anterior descending artery was the predominant vessel involved in 80% of the patients on initial presentation. Out of 10 patients, 6 were managed conservatively, 2 had emergent coronary artery bypass graft, and 2 had percutaneous coronary intervention with placement of stents. Three of the 6 patients undergoing medical management after the initial presentation had recurrence within the same hospitalization.
