Right ventricular (RV) dysfunction is one of the leading predictors of mortality and heart failure in chronic hemodialysis (HD) patients.
To describe the different echocardiographic abnormalities of the RV in subjects with HD.
We performed a descriptive cross-sectional study covering the period from July to October 2018; involving 42 patients treated with chronic HD. Patients underwent a conventional transthoracic echocardiographic (TTE) study supplemented with tissue Doppler between two hemodialysis sessions.
We included 42 patients. The sex ratio of our population was 1.6 with a male predominance, the average age of patients was 62.7 ± 12.4 years. The most important cardiovascular risk factor was arterial hypertension (78.6%). The most important causative nephropathy was nephroangisclerosis (31% of cases). The average age of dialysis was 34.5±30 months. Forty-two percent of our patients had RV dilation, 38% had right atrium dilatation, 7% had Right ventricular outflow tract dilatation, and 59.5% had RV hypertrophy. We noted RV systolic dysfunction in 66.7% of cases, a predominant normalized tricuspid profile with an average E / A ratio of 1.11 ± 0.5.
Our study is consistent with the various echocardiographic data already raised in the literature, showing a high prevalence of RV dilatation and systolic dysfunction. It is one of the leading predictors of mortality and heart failure in chronic hemodialysis patients.
右心室功能障碍是慢性血液透析(HD)患者死亡率和心力衰竭的主要预测因素之一。
描述HD患者右心室不同的超声心动图异常。
我们进行了一项描述性横断面研究,涵盖2018年7月至10月期间;纳入42例接受慢性HD治疗的患者。患者在两次血液透析期间接受了常规经胸超声心动图(TTE)检查,并辅以组织多普勒检查。
我们纳入了42例患者。我们研究人群的性别比为1.6,男性占主导,患者的平均年龄为62.7±12.4岁。最重要的心血管危险因素是动脉高血压(78.6%)。最重要的病因性肾病是肾血管硬化(31%的病例)。透析的平均时长为34.5±30个月。42%的患者存在右心室扩张,38%存在右心房扩张,7%存在右心室流出道扩张,59.5%存在右心室肥厚。我们注意到66.7%的病例存在右心室收缩功能障碍,三尖瓣形态以正常化为主,平均E/A比值为1.11±0.5。
我们的研究与文献中已提出的各种超声心动图数据一致,显示右心室扩张和收缩功能障碍的患病率很高。它是慢性血液透析患者死亡率和心力衰竭的主要预测因素之一。
