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: 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.

Aim. The survey’s aim was to examine the significance of infarct-related artery (IRA) occlusion (verified angiographically) on very long-term outcomes of patients with acute myocardial infarction, within the STEMI and NSTEMI diagnosis. Methods. A single-center, nonrandomized, registry-based study on patients treated for acute coronary syndrome with percutaneous coronary intervention between June 2011 and December 2016 was conducted. Patients with angiographically proven IRA occlusion (100% stenosis with TIMI flow 0 distal to occlusion) were categorized as occlusive myocardial infarction (OMI) and patients with patent IRA (50–99% stenosis with TIMI 1–3 flow) were categorized as nonocclusive myocardial infarction (NOMI) and very long-term outcomes were analyzed. Data were collected prospectively from the hospital’s PCI registry and the database of the Croatian Institute of Public Health. Results. A total of 2450 patients were included in the study. 796 (32.5%) patients had NOMI and 1654 patients (67.5%) had OMI. According to ECG changes, 1534 patients presented with STEMI (62,6%) and 916 with NSTEMI (37,8%). 88% of STEMI patients presented with OMI and 12% with NOMI, while patients with NSTEMI in 33,8% presented with OMI and in 66,81% with NOMI. A median follow-up was 4.7 years. There was no significant difference in cardiovascular mortality between the groups (14.8% vs 13.1%; OMI vs NOMI, respectively; p = 0.374 ) neither in all-cause mortality (19% vs 21.5%; OMI vs NOMI, respectively; p = 0.374 ). Patients with NSTEMI had a significantly higher very long-term mortality (21.6% vs 18.1%; NSTEMI vs STEMI, respectively; p = 0.029 ). Conclusion. The main findings of the study are as follows: (1) total IRA occlusion was not associated with higher long-term mortality; (2) NSTEMI was associated with a higher mortality rate compared with STEMI, independent of angiographic presentation (OMI/NOMI); (3) IRA occlusion was not associated with significantly higher mortality rates in patients with STEMI and NSTEMI, respectively.
