目的:探讨肺动脉收缩压对肺栓塞的诊断价值。方法:回顾性分析南通大学附属医院可疑肺栓塞患者110例,其中确诊肺栓塞59例,应用受试者曲线(ROC曲线)确定肺栓塞患者肺动脉收缩压的最佳临界值。结果:肺栓塞组肺动脉收缩压值[(60.25±15.03)mmHg]明显高于非栓塞组肺动脉收缩压值[(38.10±10.02)mmHg],差异有统计学意义(t=8.728,P<0.05)。应用ROC曲线确定肺栓塞患者肺动脉收缩压的最佳临界值51.5 mmHg,其灵敏度为69.5%,特异度为90.2%。结论:肺动脉收缩压可以作为疑诊肺栓塞的重要检测指标,对肺栓塞临床诊断有较高的参考价值。
Objective: To investigate the value of pulmonary artery systolic pressure in the diagnosis of pulmonary embolism. Methods: One hundred and ten suspected pulmonary embolism patients in Nantong University Affiliated Hospital were retrospectively analyzed. Fifty-nine patients were diagnosed as pulmonary embolism. The curve of the receiver operating characteristic (ROC curve) was used to determine the optimal critical value of pulmonary artery systolic pressure in patients with pulmonary embolism. Results: The pulmonary artery systolic pressure value [(60.25 ± 15.03) mmHg] in pulmonary embolism group was significantly higher than that of non-embolic pulmonary artery systolic pressure group [(38.10 ± 10.02) mmHg], the difference was statistically significant (t = 8.728, . The best cutoff value of pulmonary artery systolic pressure in patients with pulmonary embolism was 51.5 mmHg using ROC curve, with a sensitivity of 69.5% and a specificity of 90.2%. Conclusion: Pulmonary artery systolic pressure can be used as an important detection index of suspected pulmonary embolism, and has a high reference value for the clinical diagnosis of pulmonary embolism.
