Title : Effect of endurance training conducted under hypoxia conditions, on change of exercise tolerance of patients after myocardial heart infarction (STEMI) - a pilot study
It is very important to monitore closely and take appropriate precautions patients after myocardial infarction because every year many of them goes high mountain trekking or practice winter sports.
Material and methods. In 22 training units under artificial, normobaric hypoxia conditions (2000 m asl) participated 12 men after myocardial heart infarction treated with angioplasty or coronary artery bypass grafting ( 60 ± 10,60 years). Before training program all patients in normoxia conditions underwent: echocardiography examination, spiroergometric test using a treadmill, lactic acid concentration (before and after test), morphology, lipids (cholesterol, trygliceride), TNF α (tumor necrosis factor), IL 1β (Interleukin 1 β), IL1 (Inteleukin1), body mass and composition. The blood saturation was measured each time during every training. After 22 of training all examinations were repeated in normoxia conditions.
Results showed there is no danger of training in hypoxia conditions for patients. There are significant changes in parameter of treadmill test (time, MET, distance), morphology and blood saturation.
Conclusion. It is important to search some more interesting and efficient rehabilitation methods and presented results can be used during inventing some new rehabilitation programe. It can be helpful to explain weather high mountain conditions are safe for cardiac patients as well. And become introduction to analyse influence of specific other high mountain conditions as pressure, temperature, phenomenon fen, etc.
Audience take away:
- Research opens new possibilities in the rehabilitation of patients after cardiac surgery. They create an area for discussion on the use of hypoxia in accelerating rehabilitation. Research creates a new chapter on the use of hypoxia in improving patients after cardiac procedures. They are the starting point for wider multicenter research on this issue.
- The research presented at work is supposed to have a practical character. It creates a theoretical basis for the construction of hypoxia programs in the rehabilitation of people after cardiac surgery. The search for additional markers related to the impact of hypoxia on the body of cardiac patients is intended to provide new information needed in the further design of training programs
