Abstract

Prasugrel and ticagrelor are preferred over clopidogrel for patients with acute coronary syndrome who underwent percutaneous coronary intervention. We sought to determine the relative merits of 1 agent over the other. Multiple databases were queried to identify relevant randomized control trials (RCTs) and observational cohort studies. Random-effects model was used to calculate an unadjusted odds ratio (OR) for major adverse cardiovascular and cerbrovascular events (MACCE) and its components. A total of 27 (7 RCTs, 20 observational cohort studies) studies comprising 118,266 (prasugrel 62,716, ticagrelor 51,196) patients were included. At 30 days, prasugrel was associated with a significantly lower odds of MACCE (OR 0.75, 95% confidence interval [CI] 0.67 to 0.85, p ≤0.0001) and mortality (OR 0.65, 95% CI 0.59 to 0.71, p ≤0.0001). At 1 year, the overall odds of mortality favored prasugrel (OR 0.79, 95% CI 0.68 to 0.92, p = 0.002), but no significant interdrug difference was seen in terms of MACCE (OR 0.89, 95% CI 0.76 to 1.05, p = 0.16). There was no significant difference in the odds of overall myocardial infarction, revascularization, stent thrombosis, stroke, and major bleeding events between the 2 groups on both 30-day and 1-year follow-up. A subgroup analysis of RCTs data showed no significant difference between prasugrel and ticagrelor in terms of any end point at all time points. In conclusion, prasugrel might have lower odds of MACCE and mortality at 30 days. However, there was no difference in the safety and efficacy end points of 2 drugs at 1 year. The observed transient prasugrel-related mortality benefits were subject to the bias of nonrandomized assignment.
