目的:探讨超声心动图对慢性肺源性心脏病肺动脉收缩压的临床价值。方法:收集本院260例诊断为慢性肺源性心脏病的患者,定义为研究组。收集同期本院健康体检的260例健康人作为对照组。对比研究组和对照组超声心动图相关指标(右房内径、右室内径、肺动脉内径、VTR及PASP),研究组中PASP与其他超声指标的相关性。结果:研究组和对照组超声心动图相关指标(右房内径、右室内径、肺动脉内径、VTR及PASP)结果比较有差异(P<0.05);PASP与右房内径、右室内径、肺动脉内径、VTR均呈正相关,相关系数分别为(0.685、0.712、0.539、0.661)。结论:超声心动图可客观评价慢性肺源性心脏病患者肺动脉收缩压数值,对判断患者病情严重程度有重要价值。 Objective: To investigate the clinical value of echocardiography on pulmonary artery systolic pressure in patients with chronic cor pulmonale. Methods: A total of 260 patients diagnosed as chronic cor pulmonale were collected from our hospital and were defined as the study group. In the same period, 260 healthy people in our hospital were collected as control group. The echocardiographic parameters (right atrium diameter, right ventricular diameter, pulmonary artery diameter, VTR and PASP) in the study group and the control group were compared. The correlation between PASP and other ultrasound parameters in the study group was also studied. Results: There were significant differences in echocardiographic parameters (right atrium, right ventricular diameter, pulmonary artery diameter, VTR and PASP) between study group and control group (P <0.05); PASP was correlated with right atrium diameter, right ventricular diameter, pulmonary artery diameter , VTR showed a positive correlation, the correlation coefficients were (0.685,0.712,0.539,0.661). Conclusion: Echocardiography can objectively evaluate pulmonary artery systolic pressure in patients with chronic cor pulmonale, which is of great value in judging the severity of the disease.
