one approach to identify people predisposed to cardiovascular diseases is considered. Thechar acteristic value of individual time unit, τ-type of the subject, is taken as an indicator. A large sample shows that two groups of τ-types in the human population (0.8s ≤ τ ≤ 0.86s and 0.94s ≤ τ ≤ 1.0s) "prefer" to develop the ischemic heart disease. Different critical age points in the development of the disease by individuals belonging to both groups are found.
