ABSTRACT
BACKGROUND: Controlled physical training induces specific changes in the peripheral circulatory system and can lead to positive changes in the vascular perfusion of the lower extremities. OBJECTIVES: The aim of the study was to evaluate changes in peripheral circulation in the calf in patients with acute coronary disease (ACD) undergoing controlled physical training. Impedance plethysmography was used to monitor peripheral circulation during the training. MATERIAL AND METHODS: A total of 90 patients were divided into three study groups. Group 1 (n = 30) participated in a two-week cardiac rehabilitation program consisting of interval training on a cycle ergometer and exercise to improve the participants' general physical condition. Group 2 (n = 30) went through the same cardiac rehabilitation program for four weeks. The control group (n = 30) was assigned breathing exercises, active free exercises of the peripheral joints and different muscle groups, and relaxation exercises. All the patients underwent impedance plethysmography tests before and after the training sessions. RESULTS: In Group 1, the systolic slope (PSlope) increased by 2%, pulse wave amplitude (PAmpl) increased by 4.2%, crest time (CT) increased by 1.5% and propagation time (PT) decreased by 1.2% (p > 0.05). In Group 2, the PSlope and PAmpl increased by 19% and 17% respectively, while the CT and PT decreased by 8% and 6.5% respectively (p < 0.05). In the control group, only the CT decreased, by 5% (p < 0.05). CONCLUSIONS: The study confirmed that cardiac rehabilitation improves blood flow in lower limb vessels in patients with ACD. The results depend on the duration and the type of physical training. Impedance plethysmography allows for precise and repeatable monitoring of local blood flow.

Chronic obstructive pulmonary disease (COPD) and coronary artery disease (CAD) are a significant health problem, not only due to their high incidence, but also because of the significant burden of socio - economic. The frequency of illness in a population, in both cases increases with age and in people over 70 years of age is properly 50% and 75%. Epidemiological data suggest that patients with COPD are at increased risk of cardiovascular disease, and impaired lung function is an independent risk factor for cardiovascular death. This phenomenon may be related to common genetic predisposition and of systemic inflammation for atherosclerosis.
