Abstract

Background: The use of radial access for diagnostic coronary angiogram and percutaneous coronary intervention (PCI) has increased during the last few years, especially due to its benefit regarding reduction in site vascular complication compared with femoral approach.

Objectives: To evaluate the safety and feasibility of diagnostic coronary angiography in patients on chronic anticoagulation therapy without drug interruption and to study the impact of this strategy in terms of bleeding complication as first endpoint and length of hospitalisation as second endpoint.

Methods: This is a retrospective study of 53 patients on chronic anticoagulation therapy with coumarin derivatives who underwent diagnostic coronary angiography in our centre between January 2003 and July 2011, compared with a control group of 53 patients without anitcoagulation therapy. The international normalised ratio (INR) in the anticoagulated group with uninterrupted anticoagulation therapy was >2. Thrombolysis In Myocardial Infarction (TIMI) classification was used for the evaluation of bleeding complication. Hospitalisation stay was also compared between two groups.

Results: Baseline characteristics were similar in both groups except for diagnostic which motivated coronary angiogram and INR level during the procedure. A minimal bleeding occurred in the acenocoumarol group compared with 0 event in control group (1.9% vs. 0%, P=NS). The average of hospitalisation was 6±4.9 days in the acenocoumarol group and 6.3 ±4.1 in the control group (P=NS).

Conclusions: This study reveals that diagnostic coronary angiography by radial approach in patients on chronic coumarin derivative therapy without drug interruption is a safe strategy and is not associated with a significant increase in bleeding complication and length of hospitalisation.
