Aim. The aim of the study was to investigate the characteristics of daily blood pressure in 106 patients with ischemic chronic heart failure, depending on the degree of renal dysfunction. Materials and methods. We found that daily monitoring of blood pressure in patients with ischemic chronic heart can significantly increase detectability hypertension compared with office method (21.7% vs. 13.2%). Conclusions. In patients with ischemic heart failure with GFR <= 70,1 ml/min/1.73 m2 certain degree of deviation decrease in nocturnal SBP were detected in 14 (53.8%), DBP - 19 (73.1%) patients, and there are lower rates and the standard deviation of daily index for DBP in both day and at night, and the level of GFR correlated with age, functional class, blood glucose levels and the degree of blood pressure reduction at night.
