OBJECTIVE: To evaluate the effects of intra-aortic balloon counterpulsation (IABP) on mortality in patients with acute myocardial infarction according to the type of revascularization.
METHODS: Recruited randomized controlled trials of IABP compared with no-IABP controls in acute myocardial infarction patients from January 1970 to May 2015 were searched from Medline, Embase and Cochrane Library, according to inclusion criteria and exclusion criteria. These data were analyzed using the methods recommended by the Cochrane Collaboration's software RevMan 5.0. Revascularization included thrombolytic therapy, percutaneous coronary intervention (PCI), or coronary artery bypass grafting.
RESULTS: (1) Eleven randomized controlled trials were enrolled for analysis with 1 102 patients in IABP group, 1 123 in no-IABP control group. (2) Compared with no-IABP control group, IABP could not significantly decrease the in-hospital or 30 day mortality (OR=0.84, 95%CI 0.65-1.09, P=0.20). (3)Compared with no-IABP control group, IABP could not significantly decrease the in-hospital or 30 day mortality in thrombolytic patients(OR=0.64, 95%CI 0.25-1.61, P=0.34), in PCI patients (OR=0.89, 95%CI 0.68-1.18, P=0.42), and in coronary artery bypass grafting patients(OR=0.46, 95%CI 0.13-1.63, P=0.23). (4)The difference reached borderline signiicance between no-IABP control group and IABP group in patients using IABP before PCI(OR=0.47, 95%CI 0.22-1.00, P=0.05), but not in case of after PCI(OR=1.33, 95%CI 0.63-2.79, P=0.45).
CONCLUSIONS: IABP does not decrease the in-hospital or 30 day mortality of acute myocardial infarction patients who received thrombolytic therapy, PCI, or coronary artery bypass grafting. But IABP might decreases the in-hospital or 30 day mortality in patients when used before PCI.
