Diastolic pulmonary arterial pressure should be the same as wedge pressure in patients with cardiomyopathy without a known history of pulmonary vein occlusive disease. The goal of this study was to study the correlation between reported wedge pressure and pulmonary arterial diastolic pressure in patients with end-stage cardiomyopathy to evaluate the accuracy of right heart pressure reporting.
Pre-cardiac transplant patients who underwent cardiac catheterization before their heart transplantation at our institution between 2003 and 2005 (n = 159) were retrospectively reviewed. Reported diastolic pulmonary arterial pressure was correlated with reported wedge pressure.
The correlation between reported diastolic pulmonary arterial pressure with wedge pressure was modest with r = 0.75. There was wide variation with some division up to 40 mmHg. Most discrepancies occurred in the lower and higher-pressure measurements.
Among patients referred for heart transplant evaluation, a correlation between reported diastolic pulmonary pressure and wedge pressure is only modest suggesting a significant error in the reporting or measuring right-sided pressures during right heart catheterization warranting further investigation to reduce errors.
在无已知肺静脉闭塞病病史的心肌病患者中，舒张期肺动脉压应与楔压相同。本研究的目的是研究终末期心肌病患者报告的楔压与肺动脉舒张压之间的相关性，以评估右心压力报告的准确性。
回顾性分析2003年至2005年在我院接受心脏移植前进行心导管检查的心脏移植前患者（n = 159）。报告的舒张期肺动脉压与报告的楔压相关。
报告的舒张期肺动脉压与楔压之间的相关性中等，r = 0.75。存在较大差异，有些差值高达40 mmHg。大多数差异发生在较低和较高压力测量中。
在接受心脏移植评估的患者中，报告的舒张期肺压与楔压之间的相关性仅为中等，这表明在右心导管检查期间报告或测量右侧压力时存在重大误差，需要进一步调查以减少误差。
