Asian immigrants to the UK have a higher mortality from coronary artery disease (CAD) than native Caucasians. There is a clinical impression that Asians have smaller coronary arteries than Caucasians. In the present study, consecutive series of 72 male Caucasian and 70 male Asian patients undergoing diagnostic coronary angiography were recruited. Measurements of proximal disease-free segments of the three major coronary arteries were made using the catheter tip as the calibrating object. Electronic callipers were used for all measurements. Total coronary artery diameter was derived by adding the diameters of right, left anterior descending and circumflex arteries. Asians had significantly smaller total vessel diameter compared to Caucasians. They also had smaller body surface areas. This observation has important therapeutic implications regarding coronary intervention in this ethnic group already suffering excess mortality from CAD.
移民到英国的亚洲人患冠状动脉疾病（CAD）的死亡率高于当地白种人。临床上有一种印象，即亚洲人的冠状动脉比白种人小。在本研究中，招募了连续接受诊断性冠状动脉造影的72名男性白种人和70名男性亚洲患者。以导管尖端作为校准对象，对三大冠状动脉近端无病变节段进行测量。所有测量均使用电子卡尺。总冠状动脉直径通过将右冠状动脉、左前降支和回旋支动脉的直径相加得出。与白种人相比，亚洲人的总血管直径明显更小。他们的体表面积也更小。这一观察结果对于已经因CAD而死亡率过高的该种族群体的冠状动脉介入治疗具有重要的治疗意义。
