BACKGROUND: The aim of this study was to compare echocardiographic parameters in patients with autosomal dominant polycystic kidney disease (ADPKD) and in controls with normal kidney function taking into account gender and the presence of hypertension.
METHODS: 47 patients with ADPKD (age 36.3 ± 11.0 years) and 49 healthy controls (36.8 ± 9.2 years) were enrolled. M-mode echocardiography was performed in all subjects. Left ventricular hypertrophy (LVH) was diagnosed when the left ventricular mass index (LVMI) was greater than or equal to 125 g/m2 in males and 110 g/m2 in females.
RESULTS: The prevalence of LVH was greater in ADPKD patients than in controls (13% vs. 2%; p=0.05). Among females, ADPKD patients demonstrated greater LVMI (87.9 ± 18.5 vs. 68.8 ± 15 g/m2, p=0.00009) than controls. There was a positive correlation between LVMI and blood pressure in ADPKD females (Rs=0.54, p=0.027 for systole blood pressure-SBP and Rs=0.50, p=0.0053 for diastole blood pressure-DBP) but not in males.
CONCLUSION: Left ventricular mass is increased in ADPKD females with normal renal function. A positive correlation between SBP and DBP and LVMI was found in ADPKD females but not in ADPKD males.
