“…The following physiological variables were measured: test duration (min), distance covered (m), energy cost (MET), heart rate at rest (HR rest ; 1/min) and maximum (HR max ; 1/min), blood pressure at rest and maximum—systolic (BPS rest , BPS max ; mmHg), diastolic (BPD rest , BPD max ; mmHg), peak minute ventilation (VE; 1/min), breathing frequency (BF; 1/min), peak oxygen consumption (VO 2peak ) per kilogram of bodyweight. These variables were repeatedly used in studies of the level of exercise tolerance and the effectiveness of rehabilitation programs [ 4 , 15 , 16 , 17 ]. Spiroergometric parameters were determined with the CORTEX portable METAMAX 3B gas analyzer exercise test using the Excalibur Sport cycle ergometer (Lode, Groningen, The Netherlands).…”

“…The importance of exercises that are properly planned and carried out, during the second and third stage of training improvement, has been repeatedly confirmed in various scientific reports. However, these exercises were always carried out under normoxic conditions with normal oxygen content (20.94% O 2 ) [ 4 , 5 , 6 ]. Currently, the enormous progress in the field of interventional cardiology drives the search for new and even more effective forms of training that have a more dynamic impact on the development of collateral circulation.…”

The presence of a well-developed collateral circulation in the area of the artery responsible for the infarction improves the prognosis of patients and leads to a smaller area of infarction. One of the factors influencing the formation of collateral circulation is hypoxia, which induces angiogenesis and arteriogenesis, which in turn cause the formation of new vessels. The aim of this study was to assess the effect of endurance training conducted under normobaric hypoxia in patients after myocardial infarction at the level of exercise tolerance and hemodynamic parameters of the left ventricle. Thirty-five patients aged 43–74 (60.48 ± 4.36) years who underwent angioplasty with stent implantation were examined. The program included 21 training units lasting about 90 min. A statistically significant improvement in exercise tolerance assessed with the cardiopulmonary exercise test (CPET) was observed: test duration (p < 0.001), distance covered (p < 0.001), HRmax (p = 0.039), maximal systolic blood pressure (SBPmax) (p = 0.044), peak minute ventilation (VE) (p = 0.004) and breathing frequency (BF) (p = 0.044). Favorable changes in left ventricular hemodynamic parameters were found for left ventricular end-diastolic dimension LVEDD (p = 0.002), left ventricular end-systolic dimension LVESD (p = 0.015), left ventricular ejection fraction (LVEF) (p = 0.021), lateral e’ (p < 0.001), septal e’ (p = 0.001), and E/A (p = 0.047). Endurance training conducted in hypoxic conditions has a positive effect on exercise tolerance and the hemodynamic indicators of the left ventricle.

Aim. To investigate exercise tolerance in patients undergoing acute coronary syndrome with outcome in myocardial infarction, dependingon physical activity tolerance. Material and methods. We studied 80 patients aged from 40 to 75 years old who were admitted from primary vascular centers for athree-week rehabilitation course to the department of medical rehabilitation for patients with somatic diseases of the clinic of the IvanovoState Medical University of the Ministry of Health of Russia, of which 61 were men (76,3%) and 19 women (23,7%). In accordancewith the aim of the study, a 6-minute walk test was performed in all patients before and after the completion of the rehabilitationcourse. Based on the test results, physical exercise tolerance was assessed and the functional class (FC) of coronary heart disease (CHD) was determined. The patients with I class coronary heart disease (CHD) in the number of 20 patients (25%) made up the 1st group, 21patients (26,3%) with II class – the 2nd group, 21 patients (26,3%) with III class – the 3rd group, and 18 patients (22,5%) with IV class– the 4th group. Results. Every third patient who was admitted to a 3-week cardiac rehabilitation course had short-term adverse reactionson loading during physical training on simulators. Most cases of inadequate reactions were noted in patients with III and IV IHDclass III (according to the 6-minute walk test) having, according to the International Classification of Functioning, Disability and Health(ICF), moderate and pronounced reduction of exercise tolerance function. Patients often had tachycardic and hypertensive reactionsin the porcess of prysical training on stimulators and some patients (more often those with the pronounced decrease in exercise tolerancefunction) had hypotensive reaction which is the most unfavorable type of response to the load. In the vast majority of patientswith I and II CHF with no impairment or mild decrease in exercise tolerance according to ICF, an adequate response of hemodynamicparameters to exercise was determined. Adverse reactions were observed only in every fifth-seventh patient and were manifested onlyin the form of tachycardic and hypertensive reactions to exercise. The study analyzed the effectiveness of rehabilitation measures inthe groups of patients with different levels of tolerance to physical activity. It was found out that all the patients with myocardial infarction,regardless of the initial level, had increased exercise tolerance after cardiac rehabilitation. Conclusion. The 6-minute walk test is insufficiently informative for patients with markedly reduced tolerance to physical activity. The«gold standard» of qualitative and quantitative assessment of reactions and interaction between cardiovascular and respiratory systems,as well as metabolic response of the body during physical activity for these patients is the spiroergometric study.
