作者对41例有Ⅲ级以上狭窄的冠状动脉粥样斑块进行认真的形态学观察和分析,结果发现在心肌梗组(18例)平均每例斑块总数为21.4,其中45.9%为进展性斑块;而15例非冠心病死亡病例平均每例斑块总数为10,其中只有14%为进展性斑块(P<0.001)。冠心病猝死组则界于两组之间,分别为20.1和34.2%。作者认为当冠状动脉Ⅲ级以上斑块数量多、并有较多的进展性斑块时易于发生心肌梗塞和猝死。
The author of 41 patients with grade Ⅲ above coronary artery plaque serious morphological observation and analysis showed that in the myocardial infarction group (18 cases) the average number of each plaque was 21.4, of which 45.9% were progressive Plaques; while the average number of deaths per 15 cases of non-coronary heart disease per plaque was 10, of which only 14% were progressive plaques (P <0.001). Sudden death from coronary heart disease was found in two groups, 20.1% and 34.2% respectively. The authors believe that when the number of plaques above the third grade of coronary arteries and more progressive plaques prone to myocardial infarction and sudden death.
