Abstract

Purpose: to evaluate the use of indicators of dispersion mapping for the long-term prediction of adverse cardiovascular events in patients with cardiovascular diseases (CVD). The study included data of 217 people with using short recordings in dynamics throughout the year (winter, spring, summer and autumn). The 1 st group consists of 64 patients with hypertension, the 2 nd group - 44 patients with coronary heart disease, the 3rd - 30 patients with cardiomyopathy and in the 4 th group of 28 patients with coronary artery disease and diabetes mellitus. The control group consisted of 51 healthy individuals (18 men and 33 women) ranging in age from 29 to 53 years. Cardiac output was higher in the group of survivors (54,6 ± 0,5%) compared with the group with unfavorable outcome (33,8 ± 2,2%). The average values of all the indicators of dispersion mapping were higher in the group of death with the exception of heart rate index/IMM, indicating more severe violations. Noteworthy increase in 2 times the rate of alterative T wave at tT1 (Tbig) and T2 (Tmax) points. The sensitivity and specificity of the prediction of fatal outcome during 3 years of observation for record IMM > 25% was 54% and 61%.
