OBJECTIVES: To evaluate the influence of competing risk (CR) non-cardiac death during long-term follow-up of revascularized patients on the interpretation of the cardiac outcomes. METHODS: Retrospectively, we compared outcomes estimated with the Kaplan-Meier and the cumulative incidence function (CIF) methods after a median 10.8 years follow-up in 1,234 consecutive patients (594 CABG, 640 PCI) undergoing first time non-emergent revascularization in a community cohort. RESULTS: Overall 301 (24.4%) patients died (27.3% in the CABG vs. 21.7% in the PCI group, p = 0.02). The causes of death were cardiac (10.3%) and non-cardiac (14.1%). CR analysis showed a similar probability of cardiac death (CIF 0.10 (95% CI 0.092, 0.18) vs. 0.093 (0.07, 0.12)) in the CABG and PCI treated patients, respectively. The probability for acute myocardial infarction (CIF 0.12 vs. 0.16 p < 0.001), congestive heart failure (CIF 0.15 vs. 0.09 p = 0.007) in the CABG and PCI group respectively, differed. The differences were also statistically significant after multivariate adjustment for the competing risks of death. For all outcomes the Kaplan-Meier method overestimated risk estimates. CONCLUSIONS: The competing risk adjusted probability for cardiac death, but not other cardiac endpoints are comparable in patients treated with either CABG or PCI after very long-term follow-up. The risk for all-cause death was mainly predicted by the occurrence of non-cardiac diseases.
