Study on the characteristics of cardiac ultrasound in patients with chronic left heart failure caused by hypertension and its prognostic value

目的分析高血压致慢性左心功能衰竭患者心脏超声特征及其对预后的预测价值。方法选取2016年9月-2017年9月黄圃人民医院明确诊断的高血压所致心力衰竭患者60例,于随访前后分别对其进行心脏超声检查,并根据检查结果分为预后良好组38例和预后不良组22例。比较随访前和随访1年后2组超声诊断各项指标,包括左室舒张末期容积(LVDD)、左室射血分数(LVEF)、血流在二尖瓣区舒张早期最大速度(E峰)与二尖瓣在舒张早期最大速度(Ea峰)比值(E/Ea)、心脏指数(CI)。结果随访1年后,预后良好组LVEF、E/Ea、CI均高于预后不良组,LVDD低于预后不良组,差异有统计学意义(P<0.05)。结论心脏超声各项特征指数对高血压所致的左心功能衰竭患者预后具有预测价值。

Objective To analyze characteristics of echocardiography in patients with chronic left heart failure caused by hypertension and its prognostic value. Methods 60 patients with chronic left heart failure caused by hypertension diagnosed by Huangpu People’s Hospital from September 2016 to September 2017. The patients underwent echocardiography before and after follow-up,and were classified into good prognosis group( n = 38) and poor prognosis group( n = 22) according to HF-EMPS score. To compare the ultrasonic diagnosis indexes of two groups before and 1 year after follow-up. Comparison of left ventricular end-diastolic volume( LVDD),left ventricular ejection fraction( LVEF),maximum velocity of diastolic blood flow in the mitral region( E-peak),and maximal velocity ratio of mitral valve in early diastole( E/Ea),heart index( CI). Results After 1 year follow-up,the LVDD,LVEF,E/Ea,and CI in the two groups were compared after the return visit,the difference was statistically significant( P < 0. 05). The indicators of the good prognosis group were superior to the indicators of the poor prognosis group. Conclusion The characteristics of cardiac ultrasound have predictive value for the patients with left heart failure caused by hypertension.
