Background: Long term outcomes of culprit multi-vessel and left main patients who presented with Non-ST Elevation Acute Coronary Syndrome (NSTE-ACS) and underwent either coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) are not well defined. Randomized trials comparing the two modalities constituted mainly of patients with stable coronary artery disease (SCAD). We performed a meta-analysis of studies that compared the long term outcomes of CABG vs. PCI in NSTE-ACS. Methods: Medline, EmCare, CINAHL, Cochrane databases were queried for relevant articles. Studies that included patients with SCAD and ST-elevation myocardial infarction were excluded. Our primary outcome was major adverse cardiac events (MACE) at 3-5 years, defined as a composite of all-cause mortality, stroke, re-infarction and repeat revascularization. The secondary outcome was re-infarction at 3 to 5 years. We used the Paule-Mandel method with Hartung-Knapp-Sidik-Jonkman adjustment to estimate risk ratio (RR) with 95% confidence interval (CI). Heterogeneity was assessed using Higgin’s I 2 statistics. All statistical analysis was carried out using R version 3.6.2 Results: Four observational studies met our inclusion criteria with a total number of 6695 patients. At 3 to 5 years, the PCI group was associated with a higher risk of MACE as compared to CABG, (RR): 1.52, 95% CI: 1.28 to 1.81, I 2 =0% (PANEL A). The PCI group also had a higher risk of re-infarctions during the period of follow up, RR: 1.88, 95% CI 1.49 to 2.38, I 2 =0% (PANEL B). Conclusion: In this meta-analysis, CABG was associated with a lower risk of MACE and re-infarctions as compared to PCI during 3 to 5 years follow up period.

Abstract Objectives: Non-ST-elevation acute coronary syndrome (NSTE-ACS) affects millions of patients. Although an invasive strategy can improve survival, the optimal treatment (i.e., percutaneous coronary intervention [PCI] or coronary artery bypass grafting [CABG]) is not clear. We performed a meta-analysis of studies reporting outcomes between PCI and CABG in patients with NSTE-ACS.Methods: MEDLINE, EMBASE and Cochrane Library were assessed. The primary outcome was long-term mortality. Inverse variance method and random model were performed.Results: We identified 13 observational studies (48,891 patients). No significant difference was found in the primary endpoint (CABG vs. PCI, incidence rate ratio [IRR]= 0.93, 95% confidence interval [CI] 0.70; 1.23). CABG was associated with lower long-term major adverse cardiovascular events (MACE) (IRR= 0.64, 95% CI 0.54; 0.76) and lower long-term re-revascularization (IRR= 0.37, 95% CI 0.30; 0.47). There was no significant difference in long-term myocardial infarction (CABG vs. PCI, IRR= 0.96, 95% CI 0.50; 1.84) and peri-operative mortality (CABG vs. PCI, odds ratio [OR]= 1.36, 95% CI 0.94; 1.95).Conclusion: For the treatment of NSTE-ACS, CABG and PCI are associated with similar rates of long-term mortality and myocardial infarction. CABG is associated with lower rates of long-term MACE and re-revascularization. Randomized comparisons in this setting are necessary.

Background: Very little data exists regarding percutaneous coronary intervention (PCI) as an alternative to coronary artery bypass graft (CABG) for the treatment of unprotected left main disease (LMD) in octogenarians, and no studies to date have compared CABG and PCI for the treatment of LMD in this population. The objectives of our study were to compare the acute and midterm follow-up results of PCI and CABG for the treatment of significant LMD in octogenarians. Methods: A total of 163 consecutive patients ≥80 years old diagnosed with LMD have undergone coronary revascularization in our center between 2002 and 2006. One hundred and one patients underwent CABG and 62 patients had PCI (non-surgical candidates: 30%, very high surgical risk patients: 61%, patient refusal of CABG: 9%). All complications occurring within the first 30 days following the procedure were recorded, and major adverse cardiovascular events -MACCE- (cardiac death, myocardial infarction, cerebrovascular event, revascularization) were evaluated at follow-up. Results: Patients who underwent PCI were older (85 ± 3 yrs vs. 82 ± 2 yrs, p<0.0001), presented more frequently with an acute coronary syndrome (92% vs. 50%, p<0.0001), and had a higher EuroSCORE (9.5 ± 2.7 vs. 8.5 ± 2.5, p=0.01). Drug-eluting stents were used in 48% of PCI patients. There were no significant differences in the incidence of MACCE at 30 days between groups (CABG: 28%, PCI: 19%, p=0.22), but the CABG group was associated with a higher rate of atrial fibrillation (48% vs. 14%, p<0.0001) and acute renal failure (17% vs. 6%, p=0.05). The incidence of MACCE occurring between 30 days and 24 ± 17 months follow-up was higher in the PCI group (32% vs. 13%, p=0.005), but the cumulative incidence of MACCE was similar in both groups (CABG 39% vs. PCI 44%, p=0.53). Conclusions: PCI was associated with a 30-day cardiac event rate similar to that of CABG for the treatment of unprotected LMD in octogenarians. Surgical patients experienced fewer cardiac events during the follow-up period, but the cardiovascular event-free survival rate was similar between groups at 2-year follow-up. Further randomized studies with longer-term follow-up comparing both revascularization strategies in this high risk coronary population are warranted.
