چکیده انگلیسی
Among patients on hemodialysis, the mortality rate is higher in individuals with diabetes than in nondiabetic individuals, especially due to cardiovascular causes. The objective of the present study was to evaluate the role of echocardiographic abnormalities to predict mortality in diabetic patients starting hemodialysis. A 4.25-year prospective study was carried out with 40 diabetic and 28 nondiabetic patients starting hemodialysis in five dialysis centers in the metropolitan area of Porto Alegre, Brazil, between August 1996 and June 1999. Cardiovascular status was evaluated based on World Health Organization criteria, resting electrocardiogram (ECG), myocardial scintigraphy (at rest and after dipyridamole administration), and M-mode and Doppler echocardiography. Left ventricular diastolic function was classified into the following filling patterns: normal, impaired relaxation, pseudonormal, or restrictive. The survival rate was analyzed by Kaplan-Meier curves and predictors of death by Cox's proportional-hazards model. At the end of the study, the overall mortality rate was higher in patients with diabetes [19/40 (47.5%)] than in those without diabetes [2/28 (7.1%), P=.0013, log rank test]. Pseudonormal and restrictive filling patterns (HR: 3.2; 95% CI: 1.2-8.8; P=.02) and presence of diabetes (HR: 4.7; 95% CI: 1.03-21.4; P=.04) were associated with mortality. In conclusion, left ventricular diastolic dysfunction (LVDD) was the main predictor of mortality in this cohort of diabetic and nondiabetic patients starting dialysis. Intensive treatment of cardiovascular risk factors before the start of dialysis and during the treatment might reduce the mortality rate in diabetic patients.
