The aim of the study was to assess heart rate reduction for a acute decompensated heart failure in patients with reduced left ventricular systolic function and in patients with heart failure without significant reduction in ejection fraction. Were examined 79 patients with an ejection fraction less than 40%. 38 of them took If-channel blocker, ivabradine, 41 amounted to a control group. A group of patients with diastolic dysfunction was 48 patients (23 in the treatment of ivabradine and 25 subgroups of control). During the 14 days of observation it was found that the positive effect of reducing the sinus rate by ivabradine was observed in patients with diastolic dysfunction. In this group of patients on the background of decreasing heart rate, improves the passive diastolic properties of the left ventricle and an increase in the distance traveled by the patients during 6-minute walk test compared with the control group. The data obtained in our study support the use of ivabradine in patients with acute decompensated heart failure. The most significant changes in hemodynamic parameters and functional status were obtained in patients with diastolic dysfunction. Given the small sample, the results need to be further confirmed in larger clinical trials.
