Approximately 25% of patients present with acute MI. In-hospital outcomes of patients with ISR PCI are comparable with those undergoing non-ISR PCI.

Of the total patients undergoing PCI, we identified those undergoing PCI for ISR lesions. For comparison of in-hospital outcomes, propensity-score matching was employed.Abstract: OBJECTIVES: This study aims to provide an analysis of the temporal trends, clinical presentation, treatment strategies, and in-hospital outcomes of patients undergoing percutaneous coronary intervention (PCI) for ISR in the United States.Abstract: RESULTS: Among the 5,100,394 patients undergoing PCI, 10.6% of patients underwent PCI for ISR lesions. Patients with bare-metal stent ISR declined from 2.6% in 2009 Q3 to 0.9% in 2017 Q2 (p < 0.001), and drug-eluting stent ISR rose from 5.4% in 2009 Q3 to 6.3% in 2017 Q2 (p < 0.001). Patients with ISR PCI were less likely to present with non-ST-segment elevation myocardial infarction (MI) (18.7% vs. 22.5%; p < 0.001) or ST-segment elevation MI (8.5% vs. 15.7%; p < 0.001). In the propensity-matched population of patients, there were no significant differences between patients with ISR and non-ISR PCI for in-hospital complications and hospital length of stay.
