Summary:

The purpose of the study was to estimate clinical signs and course of coronary heart disease in long-livers and centenarians. Material and Methods. The study included overall population of Saratov — Engels agglomeration's long-livers (>=90 years old, n=198). Results. The rates of major clinical forms of coronary heart disease were detected: atrial fibrillation — 10.6%, chronic heart failure (with preserved ejection fraction) — 10.1 % and angina — 5.1 %. Myocardial infarction was verified in 9.6% of long-livers. Myocardial scar criteria prevailed over myocardial infarction history. Received data corroborated dissolving phenomena of coronary heart disease and noninsulin dependent diabetes mellitus in long-livers. Gender differences in electrophysiological parameters were detected in long-livers. Centenarians with the history of myocardial infarction preserved a satisfactory level of physical activity. Conclusion. Received data confirm a presence of an excessive security: prevention of coronary heart disease manifestation and progression in longevity. Long-livers should be considered as a natural model of an antiatherogenic factors and mechanisms.

Age-dependent dynamics of screening metabolic parameters in long-livers and its biophysical estimation

Summary:

The purpose of the study: to examine age-dependent dynamics of parameters of biochemical screening in long-livers. Material and methods. The study included 201 long-livers divided (Saratov) into two groups: the main group (centenarians) and the control group (90-99 y.o.). Basic parameters of biochemical screening were analyzed. Results. The suited sample of centenarians characterized by significantly lower levels of total cholesterol, triglycerids, glucose and creatinine. All studied parameters progrediently decreased from early long-livers age to centenarians. Maximal rates of age dependencies allowed us to confirm maximal weight of lipids in early longevity and glucose and creatinine in centenarians. Conclusion. All present results are most likely explained by the combined effects of genetic, environmental and "hundred years" factors leading to dynamic remodeling of control systems. Major result of such remodeling is age-dependent optimal level of metabolic factors as a mechanism of successive ageing.
