【摘要】 目的探讨超声心动图与肺部超声在左心衰伴呼吸困难病情评估中的应用价值。方法回顾性选取2019年1月至2020年1月在我院心内科治疗的左心衰患者100例,根据患者是否伴呼吸困难分组为呼吸困难组26例和无呼吸困难组74例。比较两组性别、年龄、吸烟史和基础疾病一般资料,所有患者均于入院时检查超声心动图与肺部超声,比较两组超声心动图与肺部超声图特征,采用受试者工作曲线(ROC)分析超声心动图与肺部超声预测左心衰并发呼吸困难的诊断价值。结果呼吸困难组左心房内径(LA)、左室舒张末内径(LVED)、二尖瓣舒张期早期最大流速与心房收缩期最大流速比值(E/Ea)肺部超声彗星尾征(ULCs)均高于无呼吸困难组(P<0.05);每分钟泵入全身血液量占左心室容积百分比(EF)于无呼吸困难组(P<0.05); LA、LVED、E/Ea、EF和ULCs预测左心衰发生呼吸困难的AUC分别为0.740、0.768、0.777、0.786和0.779,联合检测预测价值更高(AUC=0.963,P<0.05)。结论超声心动图与肺部超声对左心衰患者预测呼吸困难均有较高的临床价值,联合检测意义更高。更多还原

【Abstract】 Objective To explore the application value of echocardiography and pulmonary ultrasound in the evaluation of left heart failure with dyspnea.Methods A retrospective selection of 100 patients with left heart failure who were treated in the cardiology department of our hospital from January 2019 to January 2020 were grouped into dyspnea group(n=26) and non-dyspnea group(n=74).The gender, age, smoking history, and general information of underlying diseases were compared between the two groups. All patients were checked for echocardiography and pulmonary ultrasound on admission. The characteristics of echocardiography and pulmonary ultrasound were compared between the two groups. Receiver operating curve was used(ROC) To analyze the diagnostic value of echocardiography and lung ultrasound in predicting left heart failure with dyspnea.Results In the dyspnea group, left atrial inner diameter(LA), left ventricular end-diastolic inner diameter(LVED), the ratio of the maximum flow velocity in early diastole to the maximum flow velocity in atrial systole(E/Ea) of lung ultrasound comet tail signs(ULCs) All were higher than those in the non-dyspnea group(P<0.05); the total volume of blood pumped per minute to the left ventricular volume percentage(EF) was higher than that in the non-dyspnea group(P<0.05); LA, LVED, E/Ea, EF and ULCs The AUC predicting the occurrence of dyspnea in left heart failure were 0.740,0.768,0.777,0.786,and 0.779,respectively, and the combined detection had a higher predictive value(AUC=0.963,P<0.05).Conclusion Echocardiography and pulmonary ultrasound have higher clinical value in predicting dyspnea in patients with left heart failure, and the combined detection is of higher significance.更多还原
