Introduction: Ventricular hypertrophy is frequent in dialysis patients and is associated with an ominous prognosis. It is not knowledge if this ventricular change is growing or decreasing in hemodialysis patients.
Objective: To assess left ventricular hypertrophy behaviour during 17 years in patients of a university dialysis center, as well as to verify the possible causes of this behavior.
Methods: There was performed a retrospective longitudinal study that evaluated the echocardiographic left ventricular mass in hemodialysis patients in our dialysis facility over 17 years. Examinations of 250 patients aged 18 years or more who underwent routine echocardiography were included.
Results: There was a progressive reduction of ventricular mass over studied period. This reduction was associated with blood pressure reduction. In multivariate analysis, ventricular mass was associated with blood pressure and hemoglobin.
Conclusion: Left ventricular hypertrophy underwent significant reduction over 17 years in our hemodialysis patients. The factors associated with this reduction that could be identified in the current study were the progressive reduction of blood pressure and hemoglobin increase.
