“…According to the number of lesioned arteries, there were three ranks, namely, 1 lesioned artery, 2 lesioned arteries, and 3 lesioned arteries; (2) Gensini score: 1-25%, 26-50%, 51-75%, 76-90%, 91-99%, and 100% of coronary luminal narrowing were given scores of 1, 2, 4, 8, 16, and 32, respectively. This score was then multiplied by a factor based on the importance of lesion's position in the coronary arterial tree: 5 for the left main coronary artery, 2.5 for proximal segment of the left anterior descending coronary artery (LAD) or the circumfl ex artery (LCX), 1.5 for mid-segment of the LAD, 1 for distal segment of the LAD or mid-distal of LCX or right coronary artery, and 0.5 for others (Gensini 1983;Jia et al 2006). …”
