N2 - BACKGROUND: Studies have shown that chronic total occlusion (CTO) in a noninfarct-related artery in patients with ST-segment-elevation myocardial infarction is linked to increased mortality. It remains unclear whether staged revascularization of a noninfarct-related artery CTO in patients with ST-segment-elevation myocardial infarction translates to improved outcomes. We performed a meta-analysis to compare outcomes between patients presenting with ST-segment-elevation myocardial infarction with concurrent CTO who underwent percutaneous coronary intervention of noninfarct-related artery CTO versus those who did not. METHOD AND RESULTS: We conducted an electronic database search of all published data. The primary end point was major adverse cardiovascular events. Secondary end points were all-cause mortality, cardiovascular mortality, myocardial infarction, repeat revascularization with either percutaneous coronary intervention or coronary artery bypass grafting, stroke, and heart failure readmission. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed. Random effects model was used and heterogeneity was considered if I2 >25. Six studies (n=1253 patients) were included in the analysis. There was a significant difference in major adverse cardiovascular events (OR, 0.54; 95% CI, 0.32-0.91), cardiovascular mortality (OR, 0.43; 95% CI, 0.20-0.95), and heart failure readmissions (OR, 0.57; 95% CI, 0.36-0.89), favoring the patients in the CTO percutaneous coronary intervention group. No significant differences were observed between the 2 groups for all-cause mortality (OR, 0.47; 95% CI, 0.22-1.00), myocardial infarction (OR, 0.78; 95% CI, 0.41-1.46), repeat revascularization (OR, 1.13; 95% CI, 0.56-2.27), and stroke (OR, 0.51; 95% CI, 0.20-1.33). CONCLUSIONS: In this meta-analysis, CTO percutaneous coronary intervention of the noninfarct-related artery in patients presenting with ST-segment-elevation myocardial infarction was associated with a significant reduction in major adverse cardiovascular events, cardiovascular mortality, and heart failure readmissions.
