作者报道6个欧洲国家的9个医疗中心进行的联合研究,在370例(其中COPD297例,致纤维化性肺泡炎73例)中评价了多种无创技术联合预测肺动脉高压的价值.其特点是应用多种检查指标和某些新的统计或数学方法。致纤维化性肺泡炎定义为伴有弹性回缩力增加的限制性肺改变,它可由外源性因素引起,或原因不明。肺功能提示肺活量、一氧化碳弥散量及静态肺顺应性降低,而无气道阻塞。基于肺功能改变和X线检查可以作出诊断。在主要的研究内容完成以后,另外54例COPD 病例又被用于检测所得函数式的有效性。每个病例尽量在14天内完成下述检查:12导心电图、M 型超声心动图、胸片、FEV1.动脉血气pH、
The authors report a joint study of nine medical centers in six European countries evaluating the value of a combination of noninvasive techniques for predicting pulmonary hypertension in 370 patients (297 COPD, 73 fibroblastic alveolitis) characterized by Apply a variety of inspection indicators and some new statistical or mathematical methods. Fibroblastic alveolitis is defined as a limiting lung change with an increase in elastic contractility, which can be caused by exogenous factors or for unknown reasons. Pulmonary function suggests decreased lung capacity, carbon monoxide dispersion and static lung compliance without airway obstruction. Diagnosis can be made based on changes in lung function and X-ray examination. After the main study was completed, another 54 COPD cases were used to test the validity of the functional formula. The following exams were performed within 14 days of each case as possible: 12-lead electrocardiogram, M-mode echocardiography, chest radiograph, FEV 1. Arterial pH,
