Coronary angiography and Gensini scoring

Coronary angiography was performed using the Sones technique with filming of multiple views of each vessel by the same cardiologist. Significant CAD was considered present, when a stenosis of at least 50% of the lumen was found in a major coronary vessel. Moreover, the results of quantitative coronary angiography have also been expressed according to the Gensini scoring system [17]. Gensini score: stenosis <25% was recorded as 1 point, 25–49% was marked as 2 points, 50–74% was noted as 4 points, 75–90% was noted as 8 points, 91–99% was recorded as 16 points, 100% was recorded as 32 points. Factor: LM ×5, LCX opening ×3.5; left anterior descending artery, circumflex artery near, middle and far segments respectively ×2.5, 1.5, 1; right coronary ×1; D1 diagonal branch ×1; D2 diagonal branch ×0.5; left ventricular posterior branch ×1; obtuse marginal branch ×1, right posterior descending branch ×1, posterior collateral ×0.5. Gensini score = Σ (coronary stenosis × lesion factor). Gensini scoring systems were calculated by 2 cardiologists blind to the participants. Then, the mean of 2 measures was calculated. Patients with Gensini score 20 or higher were considered as serious coronary disease [18].
