目的探讨计算机X线摄影(CR)胸片对左心衰竭的诊断价值。方法选取116例呼吸困难住院患者,根据临床资料及超声心动图分为左心衰竭组和非左心衰竭组。计算CR胸片诊断左心衰竭的敏感性、特异性、准确性。结果CR胸片诊断左心衰竭敏感性88.3%、特异性94.6%、准确性91.4%。5种主要征象及出现频率如下:心影增大45例(75%);肺静脉高压47例(78.3%);间质性肺水肿37例(61.7%);肺泡性肺水肿6例(10%);胸腔积液15例(25%)。结论CR胸片对左心衰竭诊断具有较高的敏感性、特异性和准确性,有助于心源性和肺源性呼吸困难的鉴别诊断。
Objective To investigate the diagnostic value of computerized radiography (CR) chest radiography for left ventricular failure. Methods A total of 116 hospitalized patients with dyspnea were selected and divided into left heart failure group and non-left heart failure group according to clinical data and echocardiography. Calculate the sensitivity, specificity and accuracy of CR chest radiograph in the diagnosis of left heart failure. The results of CR chest X-ray diagnosis of left heart failure sensitivity 88.3%, specificity 94.6%, accuracy 91.4%. Five main signs and their frequency of occurrence were as follows: 45 cases (75%) of which had increased heart rate, 47 cases (78.3%) of pulmonary hypertension, 37 cases (61.7%) of interstitial pulmonary edema, 6 cases of alveolar pulmonary edema ); Pleural effusion in 15 cases (25%). Conclusion CR chest radiograph has a higher sensitivity, specificity and accuracy for the diagnosis of left heart failure, which is helpful for the differential diagnosis of cardiogenic and pulmonary-derived dyspnea.
