ABSTRACT
Transradial (TR) access for percutaneous coronary intervention (PCI) improves outcomes and reduces the risk of major bleeding compared with transfemoral (TF) access. However, data on gender-stratified outcomes based on vascular access are limited. Databases were queried to find relevant articles. Primary outcomes, including major bleeding complications, mortality, and secondary outcome including major adverse cardiovascular events (MACEs), myocardial infarction, and cerebrovascular accidents, were analyzed using a random-effect model to calculate unadjusted odds ratio (OR) of TR-PCI and TF-PCI between the genders. A total of 9 studies comprising 3,889,257 patients (389,580 in the TR arm and 3,499,677 in the TF arm) were included. Males comprised 73% and 67% of the TR and TF arms, respectively. TR-PCI was associated with lower major bleeding (pooled OR 0.51, 95% CI 0.40 to 0.64, p = 0.00; female OR 0.49, 95% CI 0.34 to 0.71, p = 0.00; male OR 0.54, 95% CI 0.40 to 0.73, p = 0.00) and mortality (pooled OR 0.54, 95% CI 0.45 to 0.66, p = 0.00; female OR 0.56, 95% CI 0.44 to 0.71, p = 0.27; male OR 0.54, 95% CI 0.39 to 0.75, p = 0.00) regardless of gender as compared with TF-PCI. Furthermore, TR-PCI also showed lower MACE (pooled OR 0.74, 95% CI 0.66 to 0.84, p = 0.00; female OR 0.64, 95% CI 0.59 to 0.70, p = 0.00; male OR 0.81, 95% CI 0.66 to 0.98, p = 0.00) as compared with TF-PCI in both genders. On analysis of interaction magnitude of the difference of favor of female and male for TR-PCI showed no statistically significant measurable difference. Periprocedural myocardial infarction and cerebrovascular accidents were not statistically different in TR and TF-PCI and were not different based on gender. In conclusion, TR-PCI was associated with a lower risk of major bleeding, mortality, and MACE irrespective of gender. In conclusion, TR-PCI should be the default access.
