Abstract

Abstract Background Cardiogenic shock complicates 5–10% of myocardial infarction (MI) cases. Data about the benefit of glycoprotein IIb/IIIa inhibitors (GPI) in these patients is sparse and conflicting. Methods We performed a systematic review, meta-analysis, and meta-regression of studies assessing the impact of GPI use in the setting of MI complicated cardiogenic shock on mortality, angiographic success, and bleeding events. We systematically searched for studies comparing GPI use as adjunctive treatment versus standard care in this setting. Random-effects meta-analysis and meta-regression were performed. Results Seven studies with a total of 1216 patients (GPI group, 720 patients; standard care group, 496 patients) were included. GPI were associated with a 45% relative reduction in the odds of death at 30 days (pooled OR 0.55; 95% CI 0.35–0.85; I2 = 57%; P = 0.007) and a 49% reduction in the odds of death at 1 year (pooled OR 0.51; 95% CI 0.32–0.82; I2 = 58%; P = 0.005). Reduction in short-term mortality seemed to be more important before 2000, as this benefit disappears if only the more recent studies are analyzed. GPI were associated with a 2-fold increase in the probability of achieving TIMI 3 flow (pooled OR, 2.05; 95% CI 1.37–3.05; I2 = 37%, P = 0.0004). Major bleeding events were not increased with GPI therapy (pooled OR, 1.0; 95% CI 0.55–1.83; I2 = 1%, P = 0.99). Meta-regression identified that patients not receiving an intra-aortic balloon pump seemed to benefit the most from GPI use (Z = − 1.57, P = 0.005). Conclusion GPI therapy as an adjunct to standard treatment in cardiogenic shock was associated with better outcomes, including both short- and long-term survival, without increasing the risk of bleeding.
