Summary
Maximum oxygen consumption (VO2max) is an important overall indicator of physical performance. It is also referred to as maximum aerobic capacity. Its value depends on age, sex, physical conditi on and can be improved by physical training. The main functional indicator of physiological aging is a reduction in maximum oxygen consumption. The decline in aerobic capacity is not linear but clearly accelerates with increasing age. Accelerated decline in aerobic capacity naturally has important clinical effects. Even a small improvement in aerobic capacity leads to a notice able improvement in prognosis. An increase of 1ml/ kg/ min in the consumpti on of oxygen represents a 9% improvement in prognosis. This is especially important in the case of patients with low pV02 values (<15ml/ kg/ min). Exercise capacity is not only a good prognostic indicator for patients with IHD but also for healthy persons. In both patients and healthy persons exercise capacity is a stronger predictor of increased risk of death than clinical indicators or the presence of risk factors. Managed rehabilitation programmes show an improvement in oxygen consumption of 11– 36% with the best improvement taking place in patients with the worst condition. Increased exercise tolerance is also associated with a significant reduction in fatal and non‑fatal he art attacks. These results also apply for patients with he art failure. Exercise tolerance and aerobic capacity represent an important forecasting indicator of cardiovascular and overall mortality. We should know their values for our patients and try to achieve permanent improvement in them.
Key words:
ischemic heart disease – aerobic capacity – exercise tolerance – rehabilitation
