Characteristics and consequences of myocardial infarction after percutaneous coronary intervention: Insights from the coronary angioplasty versus excisional atherectomy trial (CAVEAT)

Abstract

Myocardial infarction occurred commonly after coronary intervention in CAVEAT and was associated with a worse clinical outcome. Although the incidence of myocardial infarction was higher with atherectomy than with angioplasty, the baseline characteristics and consequences of the infarctions were similar between the treatments with regard to 30-day outcome. Myocardial enzyme elevations after an otherwise successful interventional procedure may identify a population at risk for a future cardiac event.
