Outcomes of ST-Elevation Myocardial Infarction Because of Spontaneous Coronary Artery Dissection Stratified by Involved Coronary Artery

Spontaneous coronary artery dissection (SCAD) is a nonatherosclerotic cause of myocardial infarction.1 Unlike atherosclerosis,2 treating patients with SCAD with percutaneous coronary intervention (PCI) is not associated with better outcomes.3 Because conservative therapy is preferred, its role in those presenting with ST-elevation myocardial infarction (STEMI) involving left main (LM) or proximal left anterior descending (LAD) arteries or with cardiogenic shock remains undefined. Therefore, we used the Nationwide Readmission Database (NRD) to explore the outcomes of SCAD causing STEMI, stratified by the coronary artery involved and revascularization status.
