Comparison of sequential large film coronary angiograms was performed for 58 patients with coronary artery disease, and no coronary surgery, to determine the relationship between the location, type, and degree of stenoses and their tendency to progress. Of 230 stenoses, 76 (33%) showed progression and 154 (67%) remained stable on the follow-up studies. Progression occurred in 38 (66%) patients. A statistically significant higher tendency to progress was found with tubular stenosis with ulcerating plaques (100%) and stenoses with collateral circulation (58%). A significant linear trend for progression was also found with the increasing number of risk factors of coronary disease. The above-average progression tendency of stenoses of the right coronary artery, tubular irregular stenoses, and Grade 2 stenoses, was not statistically significant.
对58例患有冠状动脉疾病且未接受冠状动脉手术的患者进行了连续大胶片冠状动脉血管造影比较，以确定狭窄的位置、类型和程度与其进展倾向之间的关系。在230处狭窄中，76处（33%）在随访研究中显示有进展，154处（67%）保持稳定。38例（66%）患者出现进展。发现伴有溃疡性斑块的管状狭窄（100%）和伴有侧支循环的狭窄（58%）有统计学上显著更高的进展倾向。随着冠心病危险因素数量的增加，也发现了显著的进展线性趋势。右冠状动脉狭窄、管状不规则狭窄和2级狭窄的高于平均水平的进展倾向无统计学意义。
