冠状动脉狭窄与猝死相关性研究

Coronary Artery Stenosis and Sudden Death Related Research

目的:探讨冠状动脉狭窄与猝死相关性。方法:选取2005年1月～2011年3月接受过心脑血管病理检查的并在有准确资料检查记录检查后一个月内发生猝死患者52例为观察组。另选取无心脑血管疾病的非猝死患者20例为对照组。分别对两组患者的的冠脉狭窄情况以及病史进行回顾性分析。结果:观察组患者中冠心病患者共22例,其中左冠脉主干狭窄者5(9.6%)例,回旋支狭窄患者11(21.2%)例,前降支狭窄患者3(5.8%)例,右冠脉狭窄患者3(5.8%)例。对照组出现1例冠脉管腔面积缩小约5.7%的患者,其余患者均无冠脉狭窄现象。观察组患者共有44例出现了不同程度的冠状动脉狭窄,占总猝死人数的84.6%,明显高于对照组。结论:心血管病史并不能作为预防猝死的主要依据,冠状动脉狭窄才是导致猝死的主要原因。

Objective：To investigate the coronary artery stenosis and sudden death.Methods：January 2005 to 2011 March,cardio-cerebral vascular examination and accurate information on the inspection record check within one month,52 cases of sudden death in patients in the observation group.20 cases of non-sudden death in patients with other select unintentional cerebrovascular disease as control group.Respectively,were retrospectively analyzed two groups of patients with coronary stenosis and history.Results：The patients with coronary heart disease in the group of patients a total of 22 cases,of which the left coronary artery stenosis in 5（9.6%） cases,the circumflex artery stenosis in patients 11（21.2%） cases,left anterior descending artery stenosis（5.8%） cases,right coronary artery stenosis（5.8%） cases.The control group one cases of coronary artery lumen area narrowed to about 5.7% of patients,the remaining patients had no coronary stenosis phenomenon.The observation group were a total of 44 cases of varying degrees of coronary artery stenosis,sudden death in 84.6% of the number of total,significantly higher than.Conclusion： a history of cardiovascular disease and not as the main basis for prevention of sudden death,coronary artery stenosis is the main cause of sudden death.
