Key result
Radial artery calcification is linked to ~2-fold higher coronary calcification prevalence and more PCI or CABG.
Why the study?
Atherosclerosis is a systemic disease across vascular beds, but studies evaluating the relationship between coronary and radial artery calcification were lacking.
Does the presence of radial artery calcification predict coronary calcification and the need for revascularization in patients undergoing coronary angiography?
Population
202 patients undergoing RUS during distal radial access and CAG at the same procedure
Comparison
Radial artery calcification vs no radial artery calcification
Design
Single-center retrospective cross-sectional study

Radial artery calcification was associated with coronary calcification and revascularization need; hypothesis-generating for noninvasive prediction and requires prospective validation.
Cross-Sectional (n=202)
No
Does the presence of radial artery calcification predict coronary calcification and the need for revascularization in patients undergoing coronary angiography?
Absolute Event Rate: 67.3% vs 32.7%
p-value: p=0.001
Radial artery calcification detected by ultrasound is significantly associated with coronary calcification and a higher need for revascularization, suggesting its utility as a predictor of coronary artery disease severity.
Achim et al. (2022) conducted a cross-sectional in Coronary artery disease (n=202). Radial artery calcification vs. No radial artery calcification was evaluated on Coronary calcification (p=0.001). Radial artery calcification was significantly associated with the presence of coronary calcification (67.3% vs. 32.7%, p=0.001) and a higher need for PCI or CABG (60% vs. 44%, p=0.02).
