OBJECTIVE: We sought to demonstrate that the combination of a local vasodilator (verapamil), modern materials, patent hemostasis, and intravenous anticoagulant only in the case of percutaneous coronary intervention, as compared to default heparin administration after sheath insertion, may optimize a combined endpoint, including radial artery oc-clusion (RAO), radial artery spasm (RAS), and access site complication.
METHODS: This is a prospective, single-center, double-blind randomized trial. Overall, 418 patients undergoing a transradial approach (TRA) for coronary procedures were randomized 1: 1 to receive intraradial verapamil (5 mg) or heparin (5,000 IU) after a 6-Fr sheath insertion. The primary outcome was the 24-h occurrence of RAO (ultrasound confirmation), access site complication, and RAS requiring the bailout administration of vasodilators.
RESULTS: The combined primary outcome occurred in 127 (30%) patients. It was significantly lower in patients randomized to verapamil as compared to others (26 vs. 35%, p = 0.03). This was mainly due to a significant reduction in RAS (3 vs. 10%, p = 0.006). The 24-h and 30-day occurrence of RAO did not differ between the study groups.
CONCLUSION: Local administration of verapamil versus heparin reduces RAS, without increasing RAO, which appears to be strictly related to radial artery diameter and hemostasis time.
