Aim: We evaluated the impact of prior percutaneous coronary intervention (PCI) on early and mid-term results in patients undergoing coronary artery bypass grafting (CABG). Methods: Between 2015 and 2020, 938 consecutive patients (mean age 67.4 ± 9.11 years) underwent CABG with prior PCI (n = 121) or primary CABG (n = 817). The mean follow-up was 37 ± 25 (median 36) months. Kaplan- Meier estimates were used to assess survival rates, while Logistic and Cox model analysis regressions assessed the risk of prior PCI and other variables. Results: Six-year survival including in-hospital mortality was 79% ± 6% in CABG with prior-PCI patients vs. 88% ± 2% in primary CABG (P = 0.002). As compared with primary CABG, in prior-PCI patients, clinical presentation (acute coronary syndrome, reduced left ventricular ejection fraction, and previous myocardial infarction, P ≤ 0.01, for all comparisons) was worse, comorbidity increased (Euroscore-2, severe chronic renal dysfunction, P < 0.01), and in-hospital mortality was higher (6.6% or 8 patients vs. 1.6% or 13 patients, P < 0.001). Prior PCI was found to be an independent predictor of mortality (HR = 4.23; P = 0.01). Six-year freedom from late all-cause death and cardiac death were 84% ± 6% vs. 90% ± 2% (P = 0.2) and 96% ± 2% vs. 96% ± 1% (P = 0.5), respectively. Independent predictors of all-cause death were advanced age at the operation (P < 0.0001), reduced left ventricular ejection fraction (P = 0.01), severe chronic renal dysfunction (P = 0.02), prior PCI (P = 0.03), and Euroscore-2 (P = 0.05). Prior PCI did not negatively affect late cardiac death (P = 0.5). Conclusion: Patients undergoing CABG after prior PCI have worse perioperative outcomes. Mid-term reduced survival in the prior-PCI patients is mainly due to the concomitant presence of worse clinical presentation and increased comorbidity. Freedom from cardiac death is comparable and satisfactory in both cohorts, highlighting the positive protective effect of CABG over time.

Abstract
Aim: We evaluated the impact of prior percutaneous coronary intervention (PCI) on early and mid-term results in patients undergoing coronary artery bypass grafting (CABG). Methods: Between 2015 and 2020, 938 consecutive patients (mean age 67.4 ± 9.11 years) underwent CABG with prior PCI (n = 121) or primary CABG (n = 817). The mean follow-up was 37 ± 25 (median 36) months. Kaplan- Meier estimates were used to assess survival rates, while Logistic and Cox model analysis regressions assessed the risk of prior PCI and other variables. Results: Six-year survival including in-hospital mortality was 79% ± 6% in CABG with prior-PCI patients vs. 88% ± 2% in primary CABG (P = 0.002). As compared with primary CABG, in prior-PCI patients, clinical presentation (acute coronary syndrome, reduced left ventricular ejection fraction, and previous myocardial infarction, P ≤ 0.01, for all comparisons) was worse, comorbidity increased (Euroscore-2, severe chronic renal dysfunction, P < 0.01), and in-hospital mortality was higher (6.6% or 8 patients vs. 1.6% or 13 patients, P < 0.001). Prior PCI was found to be an independent predictor of mortality (HR = 4.23; P = 0.01). Six-year freedom from late all-cause death and cardiac death were 84% ± 6% vs. 90% ± 2% (P = 0.2) and 96% ± 2% vs. 96% ± 1% (P = 0.5), respectively. Independent predictors of all-cause death were advanced age at the operation (P < 0.0001), reduced left ventricular ejection fraction (P = 0.01), severe chronic renal dysfunction (P = 0.02), prior PCI (P = 0.03), and Euroscore-2 (P = 0.05). Prior PCI did not negatively affect late cardiac death (P = 0.5). Conclusion: Patients undergoing CABG after prior PCI have worse perioperative outcomes. Mid-term reduced survival in the prior-PCI patients is mainly due to the concomitant presence of worse clinical presentation and increased comorbidity. Freedom from cardiac death is comparable and satisfactory in both cohorts, highlighting the positive protective effect of CABG over time.File | Dimensione | Formato | |
