BACKGROUND: During daytime working hours, outcomes may be worse when percutaneous coronary intervention (PCI) is performed later in the day because of operator fatigue and differences in process of care. METHODS: Using the APPROACH database, we analyzed 2,492 consecutive nonurgent PCI procedures performed during working hours. Patients undergoing PCI for acute coronary syndromes were excluded. Patients were separated into 2 groups based on whether PCI was started in the morning (7:00 am-12:00 pm, n = 1,446) or after noon (12:01 pm-6:00 pm, n = 1,037). Outcomes included procedural complications; target vessel revascularization (TVR); and death at 7 days, 30 days, and 1 year. RESULTS: Patients undergoing PCI in the afternoon were more likely to have heart failure, reduced ejection fraction, and Canadian Cardiovascular Society class IV or atypical angina symptoms; more likely to be inpatients; less likely to have stable angina; and less likely to receive glycoprotein IIb/IIIa inhibitors. Patients undergoing PCI in the afternoon had significantly higher unadjusted rates of the composite of death and TVR at 7 days (0.9% vs 0.3%, P = .04) and 30 days (2.0% vs 1.0%, P = .04) and death at 1 year (2.2% vs 1.1%, P = .03) compared with PCI performed in the morning. After multivariate adjustment, the differences in the composite of death and TVR at 30 days and at 1 year were not statistically significant. CONCLUSION: Patients undergoing nonurgent PCI during working hours after noon had higher rates of TVR in the first 30 days and death at 1 year. Further study is required to determine whether patient characteristics, operator fatigue, differences in process of care, or a combination of these factors accounts for the difference in outcomes.
