ACS was further classified as myocardial infarction (MI) and unstable angina. For bare metal stent, first-generation DES and second-generation DES, ACS was the clinical presentation in 67.8%, 71.0%, and 66.7% of patients, respectively (P=0.470), whereas MI occurred in 10.6%, 10.1%, and 5.2% of patients, respectively (P=0.273). The correlates for MI as ISR presentation were current smokers (odds ratio, 3.02; 95% confidence interval [CI], 1.78-5.13; P<0.001), and chronic renal failure (odds ratio, 2.73; 95% CI, 1.60-4.70; P<0.001), with a protective trend for the second-generation DES ISR (odds ratio, 0.35; 95% CI, 0.12-1.03; P=0.060). ACS presentations had an independent effect on major adverse cardiac events (death, MI, and re-target lesion revascularization) at 6 months (MI versus non-ACS: adjusted hazard ratio, 4.06; 95% CI, 1.84-8.94; P<0.001; unstable angina versus non-ACS: adjusted hazard ratio, 1.98; 95% CI, 1.01-3.87; P=0.046).Abstract: CONCLUSIONS: ISR clinical presentation is similar irrespective of stent type. MI as ISR presentation seems to be associated with patient and not device-related factors. ACS as ISR presentation has an independent effect on major adverse cardiac events, suggesting that ISR remains a hazard and should be minimized.Copyright � 2014 American Heart Association, Inc.
