A numerical index was developed for reproducible and comparative judgement of the degree of coronary sclerosis. This graded index method takes into account the amount of stenosis as well as its distance from the ostium. 152 selective coronary angiograms were evaluated by this method. There was a close correlation between the degree of sclerosis and collaterals; the index of 63 patients with collaterals was 3.5 times that of patients without collaterals. Anastomoses and collaterals showed typical localisations depending on the antomical position of stenoses. For the evaluation of the clinical importance of collaterals, a classification into one, two and three vessel disease is not adequate; the reduction in perfusion cannot be reliably estimated and should be judged by a more detailed index method.
为了对冠状动脉硬化程度进行可重复且具有可比性的判断，开发了一种数值指标。这种分级指标法既考虑了狭窄程度，也考虑了其与开口处的距离。用该方法评估了152例选择性冠状动脉造影。硬化程度与侧支循环之间存在密切相关性；有侧支循环的63例患者的指标是无侧支循环患者的3.5倍。吻合支和侧支循环根据狭窄的解剖位置显示出典型的定位。对于评估侧支循环的临床重要性而言，将其分为单支、双支和三支血管病变并不足够；灌注减少无法可靠估计，而应通过更详细的指标方法进行判断。
