title: [Blood pressures values during evaluation of 24-h ambulatory blood pressure monitoring and left ventricular hypertrophy in patients with chronic renal failure treated with hemodialysis (HD)].
abstract: Left ventricular hypertrophy (LVH) is common and important predictor of risk of death in end-stage renal failure. In the present study we have analysed the relationship between 24-h ambulatory blood pressure (BP) profile and LVH. The effect of parathyroid hormone (PTH) on was also assessed. From a cohort of 85 patients with crf we selected for analysis 59 stable patients. Ambulatory BP 24-h monitoring, echocardiography (ECHO), body mass index (BMI), serum creatinine, hemoglobin, total protein, albumin, electrolytes and PTH concentrations were assessed in all patients. Concentric LVH was detected by ECHO in 46 patients, in 13 patients excentric LVH was observed. Mean 24-h ambulatory sBP, dBP, mean 24-h ambulatory day sBP, dBP as well as night sBP and dBP were significantly higher than in a control group 60 healthy subjects. It was a correlation between mean 24-h ambulatory sBP and left ventricular mas (LVM) r = 0.606 (p < 0.0001), between mean dBP and (LVM) r = 0.498 (p < 0.001), between mean day sBP and (LVM) r = 0.591 (p < 0.0001), between mean day dBP and (LVM) r = 0.479 (p < 0.001), between mean night dBP and (LVM) r = 0.548 (p < 0.0001), between left ventricular mass index (LVMI) and mean sBP r = 0.428 (p < 0.05), between LVMI and mean day sBP r = 0.442 (p < 0.05). The loss in physiological night-time BP was observed in all patients. It was also correlations between PTH and (LVM) r = 0.704 (p < 0.001), and between BMI and LVMI r = -0.451 (p < 0.05). LVH is common in crf patients. These results confirmed that strong correlations between BP values and LVH and between serum PTH concentrations and LVH indicate that both hypertension and hyperparathyroidism play an important role in the LVH development.
