心脏性猝死72例高危因素临床探讨

Investigation of high risk factors for sudden cardiac death in 72 cases

目的探讨心脏性猝死（SCD）发病的危险因素。方法以72例心脏性猝死患者的临床资料为研究对象，进行回顾性分析。结果72例心脏性猝死患者中，男性43例，女性29例，男性中吸烟者29例；心脏扩大伴心功能Ⅲ～Ⅳ级58例；有心电图检查者61例均显示异常，其中室性心律失常65例、左室肥厚伴ST—T改变21例；低钾53例、高钾3例，正常范围9例；胆固醇升高32例，高血压病22例，糖尿病6例。猝死前有诱因者29例。结论心脏扩大伴心功能Ⅲ-Ⅳ级、左室肥厚伴ST—T改变及室性心律失常是心脏性猝死的高危因素。

Objective To investigate the correlative risk factors for sudden cardiac death （SCD）. Methods The clinical data of 72 cases with SCD were reviewed. Results Of the 72 SCD patients,43 were males （29 were smokers） ,29 were females. The abnormal findings included cardiac enlargement with function Ⅲ or Ⅳ （58 cases） , abnormal electrocardiogram （61 cases）, ventricular alThythmia （65 cases）, left ventricular plump with change of ST- T （21 cases） , Hypokalemia （53 cases ） , hyperkalemia （3 cases） and high cholesterol level （32 cases）. In addition ,22 cases were with hypertension and 6 cases with diabetes. There were inducing factors before SCD in 29 cases. Conclusion Cardiac enlargement with function Ⅲ or Ⅳ ,left ventricular thickening with change of ST- T,and ventricular arrhythmia are high- risk factors for SCD.
