Aim. To analyse 24-h rhythm of blood pressure (BP) and its influence on the rate and severity of left ventricular hypertrophy (LVH) in patients with chronic renal failure (CRF) on replacement therapy (peritoneal dialysis - PD). Material and methods. 70 CRF patients on PD were studied. Their examination included clinical, biochemical tests, automatic 24-hour blood pressure monitoring, transthoracic echocardiography. Results. Non-dipper and night-peaker disorders of BP 24-hour pattern were registered in 81.4% patients irrespective on hypertension severity. Left ventricular myocardial hypertrophy was 87.7% in patients with disturbed 24-h BP rhythm and 53.8% (p = 0.015) in normal BP rhythm. LV myocardial mass index median was 223 and 129 g/cm2 (p = 0.026), respectively. Concentric and excentric models of LV hypertrophy occurred with the same rate in normal and disturbed 24-h rhythm of BP. Conclusion. CRF patients on PD are characterized by disorders of 24-h BP rhythm independent of hypertension severity. Night-peaker pattern of BP is a risk factor of development and/or progression of LV hypertrophy.
