Comparison of Distal Radial, Proximal Radial, and Femoral Access in Patients with ST-Elevation Myocardial Infarction.

ABSTRACT: Recent studies have indicated that distal radial access (DRA) is feasible in patients undergoing percutaneous coronary intervention (PCI). The present study aimed to compare DRA, proximal radial access (PRA), and femoral access (FA) in patients with ST-elevation myocardial infarction (STEMI) undergoing PCI. Data were analyzed for 109 patients with STEMI treated via primary PCI from March 2020 to May 2021. The success rate of DRA was 83.3% (35/42), including seven cases of failed puncture (puncture failure = 5, severe radial artery spasm = 2). Primary PCI via the DRA was successful in all 35 patients. After classifying the patients requiring crossover into a separate group, the percentage of the puncture time in the door-to-wiring time was 2.7% [2.2-4.3], 3.3% [2.3-4.0], 2.6% [1.2-4.9], and 27.0% [13.5-29.3] in the DRA (n = 35), PRA (n = 24), FA (n = 26), and crossover (n = 9) groups, respectively (p < 0.01). Only two local hematomas (≤5 cm) occurred in the DRA group, while one patient in the FA group required surgical treatment and a transfusion for an access-site vascular injury. When performed by an experienced operator, DRA may represent a feasible alternative to other access routes in select patients with STEMI undergoing PCI, such as those with a high risk of bleeding.

Project description:ImportanceAmong patients with ST-segment elevation myocardial infarction (STEMI) referred for primary percutaneous coronary intervention (PCI), a survival benefit associated with radial access compared with femoral access remains controversial.ObjectiveTo assess whether there is a survival benefit when radial access is used instead of femoral access among patients with STEMI referred for primary PCI.Design, setting, and participantsThis multicenter, open-label, randomized clinical trial was conducted at 5 PCI centers in Canada. In total, 2292 patients with STEMI referred for primary PCI were enrolled between July 2011 and December 2018, with a 30-day follow-up. The primary analyses were conducted based on the intention-to-treat population.InterventionsPatients were randomized to radial access (n = 1136) or to femoral access (n = 1156) for PCI.Main outcomes and measuresInitially, the primary outcome was bleeding, but this outcome was modified to 30-day all-cause mortality following the recommendation of the granting agency. Secondary outcomes included recurrent myocardial infarction, stroke, and Thrombolysis in Myocardial Infarction-defined major or minor bleeding.ResultsAmong the 2292 patients enrolled, the mean (SD) age of the patients randomized to radial access was 61.6 (12.3) years and to femoral access was 62.0 (12.1) years, with 883 male patients in the radial access and 901 male patients in the femoral access group. The trial was stopped early following a futility analysis. Primary PCI was performed in 1082 of 1136 patients (95.2%) in the radial access group and 1109 of 1156 patients (95.9%) in the femoral access group. Bivalirudin was administered to 1001 patients (88.1%) in the radial access group and to 1068 patients (92.4%) in the femoral access group, whereas glycoprotein IIb/IIIa inhibitors were administered in only 69 patients (6.1%) in the radial access group and 68 patients (5.9%) in the femoral access group. A vascular closure device was used in 789 patients (68.3%) in the femoral group. The primary outcome, 30-day all-cause mortality, occurred in 17 patients (1.5%) assigned to radial access and in 15 patients (1.3%) assigned to femoral access (relative risk [RR], 1.15; 95% CI, 0.58-2.30; P = .69). There were no significant differences between patients assigned to radial and femoral access in the rates of reinfarction (1.8% vs 1.6%; RR, 1.07; 95% CI, 0.57-2.00; P = .83), stroke (1.0% vs 0.4%; RR, 2.24; 95% CI, 0.78-6.42; P = .12), and bleeding (1.4% vs 2.0%; RR, 0.71; 95% CI, 0.38-1.33; P = .28).Conclusions and relevanceNo significant differences were found for survival or other clinical end points at 30 days after the use of radial access vs femoral access in patients with STEMI referred for primary PCI. However, small absolute differences in end points cannot be definitively refuted given the premature termination of the trial.Trial registrationClinicalTrials.gov identifier: NCT01398254.
