摘要

一些研究表明,保留左心室收缩功能的尿毒症患者仍可能有轻微的收缩功能障碍。在我们的研究中,我们评估了常规超声心动图和二维纵向斑点跟踪测量的血液透析和非透析新近诊断为尿毒症患者的右心室(RV)和左室心肌功能。研究人群包括24名新诊断的尿毒症患者,25名血液透析患者和20名健康对照。患者的RV和LV纵向菌株显著低于对照组(- 9.6 vs. - 15.3, P <RV为0.001,- 11.3对- 14.8,p <LV为0.001)。血液透析组RV纵向应变显著低于非透析组(p = 0.018)。左心室纵应变与高血压、左室应变相关。二维纵向斑点跟踪可以检测尿毒症患者在正常收缩功能的情况下早期心室(左、右)收缩功能障碍。

2-D Speckle tracking in the assessment of left and right ventricular functions in hemodialysis versus recently diagnosed uremic patients with preserved systolic function

Several studies have demonstrated that uremic patients who have preserved left ventricular (LV) systolic function could still have subtle systolic dysfunction. In our study, we assessed the right ventricular (RV) and LV myocardial functions measured by conventional echocardiography and two-dimensional (2D) longitudinal speckle-tracking in hemodialysis and non-dialysis recently diagnosed uremic patients. The study population consisted of 24 newly diagnosed uremic patients, 25 hemodialysis patients, and 20 healthy controls. The RV and LV longitudinal strains were significantly lower in patients than in controls (−9.6 vs. −15.3, P < 0.001 for RV and −11.3 vs. −14.8, p < 0.001 for LV). In the hemodialysis group, the RV longitudinal strain was significantly lower than in the non-dialysis group (p = 0.018). The RV longitudinal strain was correlated with hypertension and LV strain. The 2-D longitudinal speckle tracking can detect early ventricular (left and right) systolic dysfunction in patients with uremia in the presence of normal systolic function by conventional methods.

期刊介绍: The Egyptian Journal of Critical Care Medicine is the official Journal of the Egyptian College of Critical Care Physicians, the most authoritative organization of Egyptian physicians involved in the multi-professional field of critical care medicine. The journal is intended to provide a peer-reviewed source for multidisciplinary coverage of general acute and intensive care medicine and its various subcategories including cardiac, pulmonary, neuro, renal as well as post-operative care. The journal is proud to have an international multi-professional editorial board in the broad field of critical care that will assist in publishing promising research and breakthrough reports that lead to better patients care in life threatening conditions, and bring the reader a quick access to the latest diagnostic and therapeutic approaches in monitoring and management of critically ill patients.
