摘　　要：目的分析心脏彩超在慢性心衰诊断中的应用效果。方法选取2019年6月至2020年12月洛阳市中医院收治的慢性心衰患者共82例设为观察组,结合左室射血分数(LVEF)划分成两组,其中LVEF正常组20例,LVEF降低组62例;结合美国纽约心脏病协会(NYHA)心功能分级:Ⅰ级15例,Ⅱ级30例,Ⅲ级21例,Ⅳ级16例。另外选取同时间段本院80名健康体检者设为对照组。均接受心脏彩超检查,统计观察组、对照组的LVEF、左心房内径(LAD)、左室舒张末期内径(LVDD)及二尖瓣口舒张早期流速峰值和舒张晚期流速峰值比值(E/A)差异,比较观察组中LVEF正常组、降低组的各项指标水平,对比观察组治疗前后的各项指标水平变化情况,并分析心功能分级和各项指标之间的相关性。结果观察组LVEF水平低于对照组,差异有统计学意义(P<0.05);LAD、LVDD及E/A水平均高于对照组,差异有统计学意义(P<0.05)。观察组中LVEF正常组LAD、LVDD及E/A水平均低于LVEF降低组,差异有统计学意义(P<0.05)。LVEF水平:心功能Ⅳ级患者<心功能Ⅲ级患者<心功能Ⅱ级患者<心功能Ⅰ级患者;LAD、LVDD、E/A水平:心功能Ⅳ级患者>心功能Ⅲ级患者>心功能Ⅱ级患者>心功能Ⅰ级患者。观察组治疗后的LVEF水平高于治疗前,差异有统计学意义(P<0.05);LAD、LVDD、E/A水平低于治疗前,差异有统计学意义(P<0.05)。相关性分析显示,心功能分级和LVEF水平之间呈负相关,和LAD、LVDD、E/A水平之间呈正相关,差异有统计学意义(P<0.05)。结论心脏彩超能够动态显示出慢性心衰患者的心脏结构、血液流速及波动速度状态,可作为慢性心衰诊断、治疗评估及治疗方案调整的重要辅助手段,在临床具备较高的应用价值。Objective To analyze the clinical effects of cardiac color ultrasound on diagnosis of chronic heart failure.Methods A total of 82 chronic heart failure patients admitted in our hospital from June 2019 to December 2020 were selected as observation group.According to left ventricular ejection fraction(LVEF),patients were classified as normal LVEF group(N=20)and declined LVEF group(N=62).According to New York Heart Association(NYHA),there were 15 gradeⅠcases,30 gradeⅡcases,21 gradeⅢcases and 16 gradeⅣcases.Over the same time period,80 healthy checkups were selected as control group.All the patients underwent cardiac color ultrasound examination.LVEF,left atrial diameter(LAD),left ventricular diastolic dimension(LVDD)and early diastolic peak flow to late diastolic peak flow velocity(E/A)values were counted in the observation group and control group and compared between normal LVEF group and declined LVEF group.The changes of the index levels before and after treatment were observed in observation group,and the correlation between cardiac function grade and the indicators was analyzed.Results LVEF level in the observation group was lower than control group,with statistically significant difference(P<0.05);LAD,LVDD and E/A levels in the observation group were higher than control group,with statistically significant differences(P<0.05);LAD,LVDD and E/A levels in normal LVEF group were lower than declined LVEF group,with statistically significant differences(P<0.05);LVEF levels were ranged from low to high:gradeⅣpatients,gradeⅢpatients,gradeⅡpatients,gradeⅠpatients.LAD,LVDD and E/A levels were ranged from high to low:gradeⅣpatients,gradeⅢpatients,gradeⅡpatients,gradeⅠpatients.In the observation group,LVEF level after treatment was higher than before,with statistically significant difference(P<0.05);LAD,LVDD and E/A levels were lower than before,with statistically significant differences(P<0.05);Correlation analysis results indicated that the cardiac function grading was negatively correlated with
