We studied the indicators of cardiovascular system in working adults (men and women) aged 22 to 76 years, and in healthy and unemployed pensioners aged 71 to 90 years. The state of the myocardium was assessed with the electrocardiogram in the 1st standard lead. Also the parameters of heart rate variability, blood pressure variability in systolic and diastolic finger blood pressure were estimated. All parameters have been normalized with respect to the age of 1620 years and translated into scores, ranked in 3 ranges of functional status: a balanced state, a sufficient state, and a tense state. For clarity of presentation of the results, we used the method of phase plane, the coordinates of which were calculated by the discriminant analysis (Root 1 and Root 2). We found the presence of a pronounced dynamics in the frequency of occurrence of different assessments of the functional state of the subjects studied. It was revealed that at the age of 45 years, representation of functionally balanced states of heart rate variability was reduced, as the prevalence of functionally ba-lanced states of averaged PQRST complex over 60 years. Representation of different values of finger blood pressure esti-mated in point scores were approximately the same in all age groups. The heart rate variability observed increase in the frequency of registration of reduced quantities power ranges HF and VLF, and high power values LF range. In the oldest age group (71-90 years) differences in the distribution of point scores of different parameters of the cardiovascular system in working and non-working pensioners were revealed. It is assumed that the "normalization" of indicators of cardiovascular system in the older age groups is not due to the actual positive changes in the state of the cardiovascular system of the elderly, but may be linked to changes in the examined sample. People who lived to the age of 70-90 years and continues to lead an active life, have better health, including with regard to the cardiovascular system than those who, even before they reach such an advanced age, are no longer afford to leave the home, and that we are actually excluded from the study.
