Coronary artery disease is one of the major cardiovascular diseases affecting the global human population. When the primary stenotic or blocked channel fails to deliver enough blood to the myocardium, the coronary collateral circulation serves as a backup source of blood supply. The aim of this study was to find out the prevalence of collateral development in patients undergoing coronary angiography in a tertiary care centre.
This descriptive cross-sectional study was conducted among patients with peripheral vascular injuries that underwent operative management in a tertiary care centre from November 2021 to April 2022. Ethical approval was taken from the Institutional Review Committee (Registration number: CMC-IRC/078/079-027). Convenience sampling technique was used. Data for the study was retrieved from operation records of the patients along with their treatment summaries. Point estimate and 95% Confidence Interval were calculated.
Among 170 patients undergoing coronary angiography, 84 (49.41%) (41.6-56.6, 95% Confidence Interval) had developed collateral circulation. The mean age was 62.8±11.7 years.
The prevalence of collateral development in the coronary artery was similar to other published literature.

冠心病是影响全球人类的主要心血管疾病之一。当主要狭窄或阻塞的血管无法向心肌输送足够的血液时，冠状动脉侧支循环就会作为血液供应的备用来源。本研究旨在了解在一家三级保健中心进行冠状动脉造影的患者中侧支发育的流行情况。
这是一项描述性的横断面研究，在 2021 年 11 月至 2022 年 4 月期间在一家三级保健中心接受外周血管损伤手术治疗的患者中进行。该研究已获得机构审查委员会的伦理批准（注册号：CMC-IRC/078/079-027）。采用便利抽样技术。研究数据来自患者的手术记录和治疗总结。计算了点估计值和 95%置信区间。
在 170 名接受冠状动脉造影的患者中，84 名（49.41%）（41.6-56.6，95%置信区间）出现了侧支循环。平均年龄为 62.8±11.7 岁。
冠状动脉侧支发育的流行情况与其他已发表的文献相似。
