    Abstract:
    The aim of the present study is to determine the prevalence and predictors of left ventricular hypertrophy in patients with stage 3 or 4 chronic kidney disease. Thirty-four patients were included. In addition to hematological and biochemical evaluations, echocardiography and ambulatory blood pressure monitoring were performed both at the beginning and at the end of the first year. Echocardiographic left ventricular mass was calculated and indexed to body surface area to calculate left ventricular mass index (LVMI). Left ventricular hypertrophy was diagnosed if LVMI >131 g/m(2) in male and >100 g/m(2) in female patients. During the follow-up period, estimated glomerular filtration rate decreased from 36.6+/-11.7 to 31.0+/-14.0 mL/min (p = 0.03), while LVMI increased from 130.2+/-35.6 to 140.5+/-30.5 g/m(2) (p = 0.055). Left ventricular hypertrophy was detected in 67.6% of the patients at the baseline and in 89.7% at the end of the study (p = 0.011). The independent predictors of the final LVMI were age (p = 0.035), baseline day-time systolic blood pressure (p = 0.01), baseline C-reactive protein (p = 0.001), and the decrease in glomerular filtration rate during the follow-up (p = 0.002). Left ventricular hypertrophy is quite frequent among patients with stage 3 or 4 chronic kidney disease, and its prevalence increases while glomerular filtration rate decreases during the follow-up. The early detection of left ventricular hypertrophy and both prevention of the deterioration of renal function and aggressive blood pressure control may help to achieve a decrease in cardiovascular morbidity and mortality in these patients.
