左室舒张末期压（LVEDP）是反映左室舒张功能的可靠指标。本研究的目的是将肺血流动力学的放射学评估与LVEDP相关联。研究人群包括104例LVEDP分为4类的连续患者：小于3 mm Hg（n = 26）、13-19 mm Hg（n = 30）、20-24 mm Hg（n = 24）和大于24 mm Hg（n = 24）。由三名实验放射科医生评估心导管插入术后24小时内获得的胸片是否存在充血性心力衰竭（CHF）的证据。根据CHF的以下体征，将结果从0到3级（正常到异常）：再分布、肺门周围和血管周围雾状混浊、支气管周围袖带、肺动脉-支气管比率、间隔线、胸膜下水肿、气腔水肿、胸腔积液、心脏扩大和CHF的总体放射学评估。然后生成了一份共识报告。在LVEDP超过20 min Hg的患者中，38%在总体评估中未显示CHF。CHF的影像学体征与LVEDP之间的相关性有限。
Left ventricular end-diastolic pressure (LVEDP) is a reliable indicator of the diastolic function of the left ventricle. The purpose of this study was to correlate the radiographic assessment of pulmonary hemodynamics with LVEDP. The study population consisted of 104 consecutive patients with four categories of LVEDP: less than 3 mm Hg (n = 26), 13-19 mm Hg (n = 30), 20-24 mm Hg (n = 24), and more than 24 mm Hg (n = 24). Chest radiographs obtained within 24 hours of cardiac catheterization were assessed for evidence of congestive heart failure (CHF) by three experimental radiologists. Findings were graded from 0 to 3 (normal to abnormal) on the basis of the following signs of CHF: redistribution, perihilar and perivascular haze, peribronchial cuffing, pulmonary artery-bronchus ratio, septal lines, subpleural edema, air-space edema, pleural effusion, cardiomegaly, and overall radiographic assessment of CHF. A consensus report was then generated. In patients with LVEDP over 20 min Hg, 38% did not show CHF in the overall assessment. Correlation between radiographic signs of CHF and LVEDP was limited.
