Abstract
To determine the factors associated with low-output left ventricular failure (LVF) in endstage renal disease (ESRD), we performed echocardiography and gated cardiac scan on 217 nondiabetic dialysis and transplant patients. The prevalence of low-output LVF (ejection fraction < 55% and left ventricular end diastolic diameter s≥ 5.5 cm) in dialysis patients was 18% and in transplant patients 2%. The 26 patients with LVF were compared to 52 controls without LVF, matched by age, sex and year of starting treatment for ESRD, but not for current ESRD therapy. Mean age was 55 ± (SEM) 14 years; 73% of the patients in both groups were males. Duration of treatment for ESRD was 5.6 ± 4.3 years in patients, compared to 5.1 ± 4.1 years in controls. Significant differences between LVF patients and controls included current treatment (73% of cases were on hemodialysis and 8% were transplanted, compared to 48 and 42%; χ2 = 9.9, p < 0.01), high serum creatinine, smoking and high serum alkaline phosphatase. There were no differences for current blood pressure, proportion on treatment for hypertension, left ventricular wall thickness, symptomatic ischemic heart disease, proportion with functioning vascular access, degree of weight gain between dialyses, hemoglobin level or high transfusion requirement. Multiple logistic regression demonstrated the most significant and independent variables associated with LVF were high alkaline phosphatase (suggestive of hyperparathyroidism), smoking and high serum creatinine levels (reflecting degree of uremia). Dialysis patients with LVF (n = 23) were compared to dialysis patients who had normal echocardiograms (n = 29). Using multiple logistic regression, the 3 most important variables associated with LVF were age, high serum alkaline phosphatase and smoking. We conclude that the most important factors associated with LVF in ESRD include age, hyperparathyroidism, smoking and degree of uremia.Keywords
