老年舒张性心力衰竭的常见病因分析

Common etiologies of elderly diastolic heart failure

目的探讨老年舒张性心力衰竭(diastolic heart failure,DHF)的可能病因及老年人DHF的基础疾病特征。方法通过填写心力衰竭调查表,体格检查,生化检查,超声心动图检查,并结合其他检查筛查出159例DHF患者及200例无DHF的老年人,记录其基础疾病的种类及患病时间分布,进行对比分析。结果DHF组原发性高血压患病率71.7%,冠心病患病率48.4%,心律失常患病率8.2%,与对照组(分别为45.0%,21.0%,2.5%)比较,患病率明显增高,差异有统计学意义(P<0.05);基础疾病为原发性高血压和冠心病者,DHF发生率随基础疾病患病时间增加呈上升趋势(P<0.05)。结论原发性高血压和冠心病是老年DHF的主要病因,心律失常也是引起DHF的重要病因。原发性高血压和冠心病患者DHF的发生率随这些基础疾病的病程延长而增加。

Objective To investigate the common etiologies in diastolic heart failure in the elderly.and probe into the character of it＇s basic diseases. Methods 159 elderly DHF patients, 200 senile healthy volunteers were selected by routine medical checkup,UCG,etc. To record and analyse the kind and taken time of the concomitant diseases. Results In DHF group,the incidence of essential hypertension, coronary heart disease and arrhythmia was71.3%, 48.1% and 8.2% respectively. It was statistically（P〈 0.05）increased compared with the normal group. The incidence of DHF increased along with the taken time of basic diseases. Conclusions Essential hypertension and coronary heart disease were the predominant causes of DHF,coronary heart disease and arrhythmia also contribute to the development of DHF. In essential hypertension and coronary heart disease patients ,the incidence of DHF increased along with the taken time of the two diseases.
