心脏性猝死临床预测因素分析

Analysis on Clinical Predictive Factors of Sudden Cardiac Death

目的分析心脏性猝死临床预测因素。方法回顾性分析本院87例心脏性猝死患者临床资料,按照年龄将患者分成30~50岁组29例,51~70岁组29例,71~90岁组29例,对各组病例可能出现的心脏性猝死预测因素进行统计。结果在30~50岁组中,大量吸烟和过度劳累占大部分;在51~70岁组中,曾有心室颤动、高危室性早搏、Q-T段延长、心室晚电位阳性相对较多;在71~90岁组中,心力衰竭且昏厥较多。结论心脏性猝死高发人群为50~70岁患者,不同年龄的患者发生心脏猝死的预测性因素也不同,针对性地进行预防治疗是降低死亡率的有效措施。

Objective To analyze clinical predictive factors of sudden cardiac death. Methods Clinical data of 87 patients with sudden cardiac death were analyzed. According totheir age, they were divided into 30 to 50 years of age for 29 cases, 51 to 70 years of age for 29 cases, 71 to 90 years of age for 29 case. The possible predictors of sudden cardiac death was compared. Results In the group at the age of30 to 50, smoking a lot of cigarettes and over exertion accounted for most part. In the group at the age of 51 to 70, there were many ven-tricular fibrillation, high risk ventricular premature beat, Q-T period of extended, ventricular late potential positive. In 71 to 90 age group,there were many heart failure and fainting. Conclusion Patients in 50-70 years old were high-risk of sudden cardiac death. The occur-rence of sudden cardiac death in patients with different age have different predictive factors, and the targeted preventive treatment is the effective measures to reduce mortality.
