The degree of pulmonary congestion seen on chest radiographs taken in the intensive care unit was compared with the end-diastolic pulmonary artery pressure in 65 patients with recent transmural myocardial infarcts without cardiogenic shock. There was good correlation between the radiographic appearances and the end-diatrolic pulmonary artery pressure, so that the severity of left heart insufficiency could be diagnosed radiologically at an early stage. Errors were due to the time interval which must pass before the radiographic appearances approximate the haemodynamic changes. This resulted in a diagnostic "phase lag" (following a rise in end-diastolic pulmonary artery pressure) or in a post-therapeutic "phase lag" (after a fall in end-diastolic pulmonary artery pressure). Repeated examinations allow one to recognize changes in the haemodynamics. One should pay particular attention to the features of pulmonary venous and pulmonary arterial hy
对65例近期发生透壁性心肌梗死且无心源性休克的患者，比较了重症监护病房胸部X线片上所见的肺充血程度与舒张末期肺动脉压。X线表现与舒张末期肺动脉压之间存在良好的相关性，因此可在早期通过放射学诊断左心功能不全的严重程度。误差是由于在X线表现接近血流动力学变化之前必须经过的时间间隔所致。这导致了诊断性“相位滞后”（舒张末期肺动脉压升高后）或治疗后“相位滞后”（舒张末期肺动脉压下降后）。重复检查有助于识别血流动力学的变化。应特别注意肺静脉和肺动脉的特征。
