Abstract

Introduction: Cardiovascular events resulting from volume overload are a primary cause of mortality in hemodialysis patients. Bioelectrical impedance analysis (BIA) is significantly valuable for assessing the volume status of hemodialysis (HD) patients. In this article, we explore the correlation between the volume index measured by BIA and the cardiac function index assessed by echocardiography (ECG) in HD patients.

Methods: Between April and November 2018, we conducted a cross-sectional study involving randomly selected 126 maintenance HD patients. Comprehensive data on medical history and laboratory test results were collected. Subsequently, we investigated the correlation between volume indices measured by BIA and cardiac function parameters by ECG.

Results: We discovered a significant correlation between the volume indices measured by BIA and various parameter of cardiac function. The Left Ventricular Hypertrophy (LVH) group exhibited higher levels of the percentage of Extracellular Water (ECW%) and the percentage of Total Body Water (TBW%) compared to the Non-LVH group. Extracellular Water (ECW) and Third Interstitial Fluid Volume (TSFV) were identified as independent risk factors for Left Ventricular Mass (LVM), and both demonstrated a high predictive value for LVM. ECW% emerged as an independent risk factor for the Left Ventricular Mass Index (LVMI), with a high predictive value for LVMI.

Conclusion: ECW and TSFV were found to be positively associated with cardiac function parameters in HD patients.

生物电阻抗测量中的容积指数对血液透析患者超声心动图心功能指数评估的影响。

导言：容量超负荷导致的心血管事件是血液透析患者死亡的主要原因。生物电阻抗分析（BIA）对评估血液透析（HD）患者的容量状态具有重要价值。本文中，我们探讨了 BIA 测量的血容量指数与超声心动图（ECG）评估的 HD 患者心功能指数之间的相关性：2018年4月至11月期间，我们进行了一项横断面研究，随机选取了126名维持性HD患者。我们收集了有关病史和实验室检查结果的全面数据。随后，我们研究了 BIA 测量的体积指数与心电图测量的心功能参数之间的相关性：结果：我们发现 BIA 测量的体积指数与各种心脏功能参数之间存在明显的相关性。与非左心室肥厚组相比，左心室肥厚组的细胞外水分百分比（ECW%）和全身水分百分比（TBW%）水平更高。细胞外水分（ECW）和第三间质容积（TSFV）被确定为左心室质量（LVM）的独立风险因素，两者对左心室质量都有很高的预测价值。ECW%是左心室质量指数（LVMI）的独立风险因素，对LVMI具有很高的预测价值：结论：ECW 和 TSFV 与 HD 患者的心功能参数呈正相关。

期刊介绍： Renal Failure primarily concentrates on acute renal injury and its consequence, but also addresses advances in the fields of chronic renal failure, hypertension, and renal transplantation. Bringing together both clinical and experimental aspects of renal failure, this publication presents timely, practical information on pathology and pathophysiology of acute renal failure; nephrotoxicity of drugs and other substances; prevention, treatment, and therapy of renal failure; renal failure in association with transplantation, hypertension, and diabetes mellitus.
