目的分析心脏彩超对高血压左心室肥厚伴左心衰竭患者心功能的评估价值。方法选取2014年2月—2016年7月新疆维吾尔自治区人民医院收治的高血压左心室肥厚伴左心衰竭患者63例作为观察组,另选取同期在本院体检健康成年人63例作为对照组。两组受试者均接受心脏彩超检查。比较两组受试者舒张早期充盈峰最大充盈速度(E值)、舒张晚期充盈峰最大峰值速度(A值)、E/A比值、左心房内径(LAD)、左心室射血分数(LVEF)、左心室舒张末期内径(LVEDD)、左心室后壁厚度(LVPWD)。结果观察组患者E值、E/A比值、LVEF低于对照组,A值、LAD、LVEDD、LVPWD高于对照组(P<0.05)。纽约心脏病协会(NYHA)分级Ⅱ级患者E值、E/A比值、LVEF高于Ⅲ级及Ⅳ级患者,Ⅲ级患者E值、E/A比值、LVEF高于Ⅳ级患者(P<0.05);Ⅱ级患者A值、LAD、LVEDD、LVPWD低于Ⅲ级及Ⅳ级患者,Ⅲ级患者A值、LAD、LVEDD、LVPWD低于Ⅳ级患者(P<0.05)。结论心脏彩超可有效评估高血压左心室肥厚伴左心衰竭患者心功能,判断患者病情严重程度。
Objective To evaluate the value of echocardiography in evaluating cardiac function in patients with left ventricular hypertrophy and left ventricular failure. Methods Sixty-three hypertensive patients with left ventricular hypertrophy and left ventricular hypertrophy were selected from the People’s Hospital of Xinjiang Uygur Autonomous Region from February 2014 to July 2016 as the observation group. 63 healthy adults were selected as the control group in the same period. Two groups of subjects underwent echocardiography. The peak filling velocity (E), the maximum peak velocity (A), E / A ratio, left atrium diameter (LAD), left ventricular ejection fraction (LVEF) , Left ventricular end-diastolic dimension (LVEDD) and left ventricular posterior wall thickness (LVPWD). Results The E value, E / A ratio and LVEF in the observation group were lower than those in the control group. The values of A, LAD, LVEDD and LVPWD in the observation group were higher than those in the control group (P <0.05). The E value, E / A ratio, LVEF in NYHA Class Ⅱ patients were higher than those in Grade Ⅲ and Ⅳ patients, and those in Grade Ⅲ E patients, E / A ratio and LVEF were higher than those in Grade Ⅳ patients (P <0.05) ). The level of A, LAD, LVEDD and LVPWD in patients with grade Ⅱ were lower than those in patients with grades Ⅲ and Ⅳ. The level of A, LAD, LVEDD and LVPWD in patients with grade Ⅲ were lower than those in patients with grade Ⅳ (P <0.05). Conclusions Echocardiography can effectively evaluate the cardiac function in patients with left ventricular hypertrophy and left ventricular failure to determine the severity of the disease.
