• W2078359984 abstract "In the past few years in Western countries, there has been an increasing proportion of elderly patients beginning renal replacement therapy. Left ventricular hypertrophy (LVH) is associated with an increased mortality rate due to cardiovascular disease, the main cause of death in patients on chronic hemodialysis. In this study, we evaluated 67 chronic hemodialysis patients older than 65 years (33 women and 34 men; mean age, 72.6 years; mean time on chronic hemodialysis, 51.3 months). Several biological and laboratory data were analyzed. The left ventricular mass was calculated using the Penn convention criteria. LVH was observed in 49 patients (73%). These 49 patients were divided into two groups (group 1, concentric hypertrophy, n = 22; and group 2, eccentric hypertrophy, n = 27) and compared with a control group (patients without LVH, n = 18). Group 1 (P = 0.06) and group 2 (P = 0.055) showed higher systolic blood pressures and group 2 showed a lower hematocrit (P = 0.024). The echocardiographic parameters were expectedly different: group 1 had higher posterior left ventricular wall thickness (P = 0.0001), interventricular septum thickness (P = 0.0001), and left ventricular wall relative thickness (P = 0.002), and group 2 had higher left ventricular end-diastolic diameter (P = 0.0001), interventricular septum thickness (P = 0.01), and posterior left ventricular wall thickness (P = 0.023). Using the left ventricular mass index as the dependent variable and the evaluated biological and laboratory data as the independent variables, we found in a stepwise multiple regression model that only systolic blood pressure (t = 3.430; P = 0.0011), age (t = 2.059; P = 0.044), interdialytic weight gain (t = 2.236; P = 0.029), and hematocrit (t = -1.961; P = 0.054) independently influenced the left ventricular mass index (R2 = 0.313; P = 0.0001). Further studies are needed to determine whether reduction of the left ventricular mass index, through control of blood pressure and correction of anemia, will decrease the cardiovascular events in this particular population." @default.
