Abstract

Objectives The aim of this study was to compare outcomes of ST-segment elevation myocardial infarction (STEMI) patients with a history of coronary artery bypass graft surgery (CABG), previous percutaneous coronary intervention (PCI), or no previous revascularization undergoing primary PCI. Background Limited data exist regarding door-to-balloon times and clinical outcomes of STEMI patients with a history of CABG or PCI undergoing primary PCI. Methods We examined 15,628 STEMI patients who underwent primary PCI at 297 sites in the United States. We used multivariable logistic regression analyses to compare door-to-balloon time delays >90 min and in-hospital major adverse cardiovascular or cerebrovascular events (MACCE). Results Patients with previous CABG were significantly older and more likely to have multiple comorbidities (p < 0.0001). Previous CABG was associated with a lower likelihood of a door-to-balloon time >90 min compared with patients with no previous revascularization. However, no significant differences in door-to-balloon times were noted between patients with previous PCI and those without previous revascularization. The unadjusted MACCE risk was significantly higher in patients with a history of CABG compared with patients without previous revascularization (odds ratio: 1.68, 95% confidence interval: 1.23 to 2.31). However, after multivariable risk adjustment, there were no significant differences in MACCE risk between the 2 groups. No significant differences in in-hospital outcomes were seen in patients with a previous PCI and those without previous revascularization. Conclusions In a large cohort of STEMI patients undergoing primary PCI, patients with previous CABG were more likely to have reperfusion delays, yet risk-adjusted, in-hospital outcomes were similar to those without previous revascularization. No significant differences in reperfusion timeliness and in-hospital outcomes were seen in patients with a history of PCI compared with patients without previous revascularization.
