Radial artery calcification in predicting coronary calcification and atherosclerosis burden

Abstract Background Atherosclerosis is a systemic arterial disease with heterogeneous involvement in all vascular beds, however studies examining the relationship between coronary and radial artery calcification are lacking. The purpose of this study was to assess two sites prognostic value (RC) for disease. Methods results This single-center, retrospective cross-sectional based on doppler ultrasound (RUS) angiography (CAG). We included total 202 patients undergoing RUS during distal access CAG at same procedure, December 2020 May 2021, from which 103 were found having RC (RC-group) 99 without (NRC-group). Coronary calcifications evaluated either by examination (moderate severe), positive CT (>100 Agatson units) or intracoronary imaging (IVUS, OCT). A significant correlation observed variables (67.3%, vs 32.7% – p=0.001). risk factors such as age, smoking, chronic kidney diabetes mellitus higher while sex did not play role. need PCI and/or CABG RC-group (60% 44%, p=0.02). therefore predicts extent severity Conclusion may be frequently associated calcific plaques. These findings highlight potential beneficial arteries whenever CAD suspected. Funding Acknowledgement Type funding sources: None.
