RESUMO
AIMS: There are limited data on outcomes of PCI in surgical turndown patientsespecially in those presenting with ACS. METHODS AND RESULTS: A retrospective analysis of prospectively collected data of patients who were turned down for CABG and had PCI between 2013 and 2020. All consecutive patients (449), ACS (n = 245) and no-ACS (n = 204) were included. In-hospital complications occurred in 28 patients (6.2%). At 30 days, 27 patients (6.0%) died (18 patients in the ACS group [7.3%] vs. 9 patients in the no-ACS group [4.4%], p = 0.23). Following multivariate analysis, no significant difference in long-term mortality was observed between the two groups (median follow-up of 4 [2-6] years, hazard ratio [HR]: 1.08, 95% confidence interval [CI]: 0.75-1.58, p = 0.667). In propensity score-matched analysis, the adjusted mortality risk was also not different between the groups (HR: 0.74, 95% CI: 0.25-1.26, p = 0.374). Independent predictors of mortality included chronic kidney disease stage ≥ 3 (HR: 1.64, 95% CI: 1.13-2.39, p = 0.009), high European System for Cardiac Operative Risk Evaluation II (HR: 1.02, 95% CI: 1.00-1.05, p = 0.035), and laser atherectomy use (HR: 3.35, 95% CI: 1.32-8.54, p = 0.011). CONCLUSIONS: PCI in surgical patients turndown patients appears safe. ACSpresentation was associated with more comorbid illnesses; however, afteradjustment, ACS did not independently confer additional risk of mortality.
