急性脑血管病患者心源性猝死的危险因素

Sudden cardiac death in patients of acute cerebrovascular disease

目的 探讨急性脑血管病 (ACVD)中心源性猝死(SCD)的发生率及其有关因素 .方法 观察了急性脑血管病患者 494例心源性猝死的发生率和发生时间 ,并通过与非猝死者比较 ,分析了其病初心电的改变以及与病变部位和病情的关系 .结果 心源性猝死发生率为 2 .4% ,病初心电图异常率为 91.7% ,明显高于非猝死者 (P <0 .0 5 ) .心源性猝死主要见于病情较轻的脑梗死 (CI)患者 ,年龄相对集中在 5 6(5 6± 9)岁 ,与性别关系不大 ,与病变部位无关 .结论 急性脑血管病患者心源性猝死好发于轻型脑梗死患者 。

AIM To study the incidence and related factors of sudden cardiac death (SCD) in patients of acute cerebrovascular disease (ACVD). METHODS The incidence and occurring time of SCD in 494 cases of ACVD were observed. By comparing with non sudden death cases, the relationships between SCD incidence and factors such as changes of ECG at the early stage of the disease, cerebral lesion sites, age, sex and severity were analyzed. RESULTS The incidence of SCD is 2.4%. Abnormality rate of ECG in SCD patients in the early stage is 91.7%, significantly higher than that of the non sudden death patients ( P <0.05). Most SCD occurred in patients with small functional deficits cerebral infarction. The age of SCD patients is around 56 (56±9). There was no significant correlation between the SCD and sex or lesion site. CONCLUSION SCD of ACVD is most likely to occur in mild cerebral infarction patients. The risk of SCD exists throughout the first month of stroke.
