Randomized clinical study on radial artery compression time after elective coronary angiography

Area of Science:

• Cardiology
• Vascular Surgery
• Interventional Radiology

Background:

• Transradial coronary angiography is a common procedure.
• Achieving effective hemostasis and minimizing vascular complications are crucial post-procedure goals.
• Optimizing compression strategies can improve patient outcomes.

Purpose of the Study:

• To compare the efficacy of two different radial artery compression durations (30 vs. 60 minutes) following coronary angiography.
• To assess the impact of compression time on hemostasis achievement and the incidence of vascular complications.

Main Methods:

• A randomized clinical study involving patients undergoing elective transradial coronary angiography.
• Two groups were compared: 30-minute compression (G30) and 60-minute compression (G60).
• Outcomes included hemostasis, immediate and late radial artery occlusions, and hematomas, assessed via clinical evaluation and Doppler ultrasonography.

Main Results:

• Hemostasis was achieved in 76.3% of G30 patients and 84.2% of G60 patients (p=0.063).
• Immediate complications included hematomas (53) and radial artery occlusions (38).
• Late radial artery occlusions occurred in 5.5% of G30 and 8.2% of G60 patients.

Conclusions:

• The duration of radial artery compression (30 vs. 60 minutes) after coronary angiography did not significantly affect hemostasis or the occurrence of vascular complications.
• Current compression protocols may be flexible without compromising safety or efficacy.
