Comparison of the risk of vascular complications associated with femoral and radial access coronary catheterization procedures in obese versus nonobese patients

In this retrospective review of 5,234 cardiac catheterizations and percutaneous coronary interventions, the rate of vascular complications was highest in extremely thin and morbidly obese patients and lowest in moderately obese patients, consistent with the previously reported “obesity paradox.” The use of transradial access and arterial access closure devices was associated with reduced vascular complications in the population of obese patients.
