Transradial versus transfemoral percutaneous coronary intervention in acute myocardial infarction Systematic overview and meta-analysis.

Background: Although transradial percutaneous coronary intervention (TRPCI) is widely applied for percutaneous procedures, its safety in the setting of ST-segment elevation (STEMI) is controversial. Our aim was to assess the safety and efficacy of TRPCI versus transfemoral PCI in the context of treating patients suffering acute myocardial infarction with STEMI.

Methods: Randomized, case-control, and cohort studies comparing access-related complications were analyzed. Our objective was to determine if radial access reduces major bleeding and thereby reduces death and ischemic events compared to femoral access in this setting. A fixed-effects model was used with random effects for sensitivity analysis.

Results: Twelve studies involving 3324 patients were identified. Transradial PCI reduced major bleeding compared to transfemoral PCI (P = .0001), and significant reductions were found in the composite of death, myocardial infarction, or stroke (P = .001). Mortality reduction showed a significant toward benefit in the case of TRPCI (2.04% vs 3.06%, OR 0.54 [95% CI 0.33-0.86], P = .01). The fluoroscopic time was longer, and access site crossover was more frequent for TRPCI (P = .001, P < .00001, respectively).

Conclusions: Transradial PCI reduces the risk of periprocedural major bleeding and major adverse events in the STEMI setting.
