Abstract

A study was undertaken to determine whether measurements of radiological indices from chest X-rays and body mass index (BMI) were useful in predicting pulmonary artery hypertension. Measurements of the cardiothoracic ratio (CTR) as well as right descending pulmonary artery diameter (RDPA) and BMI were made in 27 patients with chronic obstructive pulmonary disease (COPD). Mean pulmonary arterial pressure (mPA) correlated with CTR, RDPA and BMI. Multiple regression analysis gave the useful equation: predicted mPA = -3.523 + 0.196xBMI + 0.110xCTR + 0.786xRDPA (r = 0.704, p < 0.002). Fifteen patients were found to have pulmonary hypertension, defined as mPA > or = 20 mmHg. The sensitivity of CTR and BMI were 86.7%. The specificity of BMI was 83.3%. These results suggest that the measurements CTR, RDPA and BMI may be useful in screening for pulmonary hypertension in patients with COPD.

摘要

开展了一项研究以确定胸部X光的放射学指标测量值和体重指数（BMI）是否有助于预测肺动脉高压。对27例慢性阻塞性肺疾病（COPD）患者进行了心胸比（CTR）、右下肺动脉直径（RDPA）及BMI测量。平均肺动脉压（mPA）与CTR、RDPA及BMI相关。多元回归分析得出有效方程：预测mPA = -3.523 + 0.196×BMI + 0.110×CTR + 0.786×RDPA（r = 0.704，p < 0.002）。发现15例患者患有肺动脉高压，定义为mPA≥20 mmHg。CTR和BMI的敏感性为86.7%。BMI的特异性为83.3%。这些结果表明，CTR、RDPA及BMI测量值可能有助于筛查COPD患者的肺动脉高压。
