Abstract

IntroductionThe aim of this study was to investigate changes in echocardiographic right ventricular (RV) indices in relation to the degree of fluid accumulation between hemodialysis sessions, evaluated according to the recommended threshold of interdialytic‐weight‐gain corrected for dry weight (IDWG%).MethodsA post‐hoc analysis was performed using data from 41 maintenance hemodialysis patients. Patients were divided into a higher (>4.5%) and a lower (<4.5%) IDWG% group and underwent an echocardiographic assessment at the start and the end of the 3‐day and the 2‐day interdialytic interval.ResultsRV systolic pressure (RVSP) increments were more pronounced in the higher compared to the lower IDWG% group (16.43 ± 5.37 vs. 14.11 ± 13.38 mm Hg respectively, p = 0.015) over the 3‐day interval, while changes in RV filling pressures, did not differ significantly between the groups (p = 0.84).ConclusionsDuring the 3‐day interdialytic interval, pulmonary circulation is particularly overloaded in patients with fluid accumulation higher than the recommended thresholds, as evidenced by higher RVSP elevations.

维持性血液透析患者的右心室尺寸、功能和肺循环负荷随透析间期体重增加程度而发生的变化

简介：本研究的目的是研究超声心动图右心室（RV）指数的变化与血液透析疗程间液体积聚程度的关系，根据推荐的透析间期体重增加校正干重（IDWG%）阈值进行评估。方法利用 41 例维持性血液透析患者的数据进行了事后分析。患者被分为IDWG%较高（>4.5%）和较低（<4.5%）两组，并在3天和2天透析间歇期开始和结束时接受超声心动图评估。结论在 3 天的间歇期内，液体积聚超过推荐阈值的患者肺循环负荷尤其过重，这表现为 RVSP 升高。
