A Comprehensive Single-Center Retrospective Analysis of the Prevalence and Demographic Features of Myocardial Bridges in Northern Cyprus

Background: Myocardial bridging (MB) is an anatomical variant in which segments of epicardial coronary arteries course partially within the myocardium. The prevalence of MB is reportedly as high as 15–85% in autopsy studies, whereas coronary angiography studies show a prevalence ranging from 0.5–3%. The aim of this study was to investigate the prevalence and demographic characteristics of MB in patients undergoing coronary angiography in Northern Cyprus. Methods: This retrospective review analyzed coronary angiography data for 6980 consecutive adult patients undergoing coronary angiography between December 2020 and January 2023. Results: MB was detected in 89 of 6980 patients who underwent coronary angiography, giving an angiographic prevalence of 1.27%. The mean age of patients was 59.4 ± 13.5 years (range: 26–90 years), with 28 (31.5%) females and 61 (68.5%) males. MB was most commonly observed in the left anterior descending (LAD) artery. MB was found in the middle LAD segment in 65 patients (73.0% of all cases), in the distal LAD segment in 22 patients (24.7%), and in the right coronary artery (RCA) in two patients (2.2%). Conclusion: This study provides new data on the prevalence of MB in Northern Cyprus and on regional differences in this condition. Further epidemiological research is needed to better characterize MB distribution and its potential clinical significance.
