RESUMEN
<p><b>OBJECTIVE</b>To compare coronary lesion characteristics by coronary angiography (CAG) between yellows and whites.</p><p><b>METHODS</b>CAG results of 3021 Chinese patients, defined as yellows, from Nanjing and 3230 Australian patients, defined as whites, from Sydney were analyzed. The coronary artery lesion was evaluated by the number and location of coronary lesion and Gensini scores.</p><p><b>RESULTS</b>(1) Coronary stenosis was diagnosed in 69.4% Chinese patients and 75.5% in Australians. The involved coronary arteries were left anterior descending branch, right coronary artery, left circumflex branch and left main coronary artery in a descending order in both Chinese and Australians. (2) The incidences of three-vessel disease and left main disease of yellows were significantly lower than that of whites in both male (29.8% vs. 34.0% and 9.6% vs. 14.2%) and female patients (15.8% vs. 26.2% and 4.9% vs. 11.6%) respectively, all P < 0.05. (3) There was an age-dependent Gensini scores increase in both yellows and whites patients and Gensini scores at age 40 and more of whites were significantly higher than those of yellows in comparable age groups.</p><p><b>CONCLUSION</b>The incidences of three-vessel disease and left main disease as well as Gensini score were significantly higher in Australian patients than those of Chinese patients.</p>
