Abstract:
Objective:To investigate the risk factors of left ventricular hypertrophy (LVH) in non-dialysis dependent end-stage renal disease (ESRD) patients.
Methods:ESRD patients in the First Affiliated Hospital of Sun Yat-sen University from Jan to July 2019 were enrolled. Demographic data of patients were collected and biochemical parameters were measured. Hydration status index (extracellular water/total body water, ECW/TBW) was measured by bioelectrical impedance analysis (BIA), and LVH was diagnosed by echocardiography. Patients were divided into LVH group and non-LVH group according to LVH diagnostic criteria, and the incidence of LVH in ESRD non-dialysis patients was calculated. Logistic regression was used to analyze the risk factors of LVH.
Results:A total of 105 non-dialysis dependent ESRD patients aged (47.03±12.56) years (21-78 years) were enrolled in present study, among whom 74 patients (70.5%) had LVH. Compared to non-LVH group, patients in LVH group had higher proportion of diabetes and calcium antagonist used, higher value of ECW/TBW and ECW/Height, higher level of night systolic pressure, and were older (all P<0.05). Spearman correlation analysis showed LVH was positively correlated to diabetes (r=0.345, P<0.001), night systolic pressure (r=0.286, P<0.001), night diastolic pressure (r=0.251, P=0.012), calcium antagonist used (r=0.381, P=0.013), ECW/TBW (r=0.383, P=0.005), ECW/Height (r=0.298, P=0.003), 24 h sodium urinary excretion (r=0.257, P=0.025), brain natriuretic peptide (r=0.315, P=0.005) and hemoglobin (r=0.307, P=0.018), and negatively correlated to 24 h potassium urinary excretion (r=-0.248, P=0.023). Logistic regression showed that increased night diastolic pressure (OR=2.036, 95%CI 1.144-3.623, P=0.016) and ECW/TBW (OR=1.232, 95%CI 1.025-1.523, P=0.014) were the independent risk factors of LVH after adjusting for gender, age, diabetes, nocturnal blood pressure, antihypertensive drugs used, ECW/TBW, urinary sodium excretion and hemoglobin.
Conclusions:LVH is common in non-dialysis dependent ESRD patients. Over hydration and high night diastolic blood pressure are the independent risk factors of LVH in non-dialysis dependent ESRD patients.
