Elderly patients had more severe acute myocardial infarction and more extensive disease, a lower index of success, and greater in-hospital mortality. Previous infarction, anterior location and male sex were identified as predictors of mortality in the elderly group (GI).

Background: Studies demonstrate that radial artery access reduces the risk of vascular and bleeding complications associated to percutaneous coronary intervention. Our objective was to evaluate in-hospital results of the transradial approach in elderly patients undergoing percutaneous coronary intervention. Methods: Prospective registry including patient's ≥ 70 years of age; safety and efficacy endpoints were compared for the radial and femoral artery access groups. Results: We included 255 patients, 117 (52%) treated using the radial approach and 108 using the femoral approach. Except for age, the remaining clinical characteristics did not show differences between groups. Male patients prevailed (60%), 36.7% were diabetic and over one third were diagnosed with acute coronary syndrome. Angiographic and procedure-related variables did not show differences between groups. When vascular complication rates were compared only hematomas < 5 cm (5.1% vs. 17.6%; p < 0.01) were more prevalent with the femoral access. Major bleedings, according to the ACUITY criteria (zero vs. 5.6%; p = 0.01) and minor bleedings, according to the TIMI criteria (zero vs. 7.4%; p < 0.01), were also more frequent in the femoral group. In-hospital clinical endpoints, death (0.9% vs. 5.6%; p = 0.06) and non-fatal infarction (zero vs. 3.7%; p = 0.05) were more frequent in patients treated by the femoral access. Conclusions: In a non-selected patient population ≥ 70 years of age, percutaneous coronary intervention by radial access was associated to a lower incidence of in-hospital clinical endpoints, especially of bleeding events related to the vascular access route.
