超声心动图对慢性肺源性心脏病的临床应用价值

Echocardiographic evaluation of chronic pulmonary heart disease

目的探讨超声心动图对慢性肺源性心脏病的临床应用价值。方法回顾收集临床确诊为慢性肺源性心脏病、经超声心动图证实、除外其它心血管疾病和急性感染性疾病的96例患者的临床及超声心动图资料,并根据所测肺动脉收缩压的高低,将患者分为轻、中、重度组,与49例健康对照组进行比较。结果轻度患者38例(40%),中度患者37例(39%),重度患者21例(22%),肺动脉收缩压分别为(41.51±5.01)mm Hg(1 mm Hg=0.133 kPa)、(54.21±3.00)mm Hg、(90.13±11.40)mm Hg。治疗2周后复查,轻度组38例(100.0%)、中度组23例(62.2%)、重度组5例(25.0%)患者肺动脉收缩压降至正常,其余中度组及重度组患者2周后肺动脉收缩压明显降低。超声心动图所测结果与患者临床表现转归一致。结论实时彩色超声心动图能够定性和定量监测肺动脉收缩压,客观评价慢性肺源性心脏病的临床诊断、病情程度、疗效观察及预后评估。

Objective To explore the utility of echocardiography in the diagnosis of chronic pulmonary heart disease （CPHD）. Methods A retrospective study was conducted to investigate the utility of echocardiography in diagnosis of 96 patients with CPHD excluding acute infectious disease and other cardiovascular diseases. All patients were divided into light, moderate, severe group according on the pulmonary artery systolic pressure. 49 normal subjects were employed as control. Results All 96 patients included 38 cases of light CPHD（40% ） ,37 cases of moderate CPHD（39% ） ,21 cases of severe CPHD（22% ）, and the pulmonary artery systolic pressure were（41.51 ± 5.01 ） mm Hg, （54.21± 3.00） mm Hg and （90.13 ± 11.40） mm Hg, respectively. 2 weeks after the treatment, the pulmonary artery systolic pressure returned to normal levels in 38 cases of light CPHD（ 100.0% ） ,23 cases of moderate CPHD（62.2% ） ,and 5 cases of severe CPHD（25.0% ）, the other patients of three groups recovered 2 weeks later. The results of echocardiography were consistent with the clinical outcome. Conclusion Real-time three-dimensional echocardiography can provide a qualitative and quantitative analysis of the pulmonary artery systolic pressure, objectively assess the clinical diagnosis, severity of disease,curative effect and prognosis of CPHD patients.
