Fizjoterapia Polska 2007; 7(3); 362-369

Abstract
Background. The aim of this study was to estimate the influence of whole-body cryotherapy on some selected parameters of the circulatory system. Material and methods. The investigation involved 7 male patients with ankylosing spondylitis. They were exposed to a cycle of 10 everyday 2 minute-lasting procedures of whole-body cryotherapy at a temperature of -130°C which was followed by subsequent kinesitherapy. Patients treated with drugs influencing the circulatory system and suffering from circulation and hormonal system disorders were excluded. During the day preceding the beginning of cryotherapy procedures and once more, after finishing whole-body cryotherapy cycle, echocardiography with calculation of left ventricle ejection fraction (LVET), record and analysis of heart rate variability (HRV), late ventricular potentials and QT dispersion were made. Results. No significant differences between ejection fraction, late ventricular potentials, QT dispersion values before and after the end of cryotherapy cycle were found. Whole-body cryotherapy evoked increase in total heart rate variability, which was statistically significant for most of the parameters in time analysis. Spectrum analysis showed statistically insignificant increase in spectrum power in the full range of analyzed frequencies. Conclusions. Long-lasting whole-body cryotherapy does not influence ejection fraction, late ventricular potentials and QT dispersion in patients without significant pathology of circulation. Cryogenic temperatures applied on the whole-body exerts beneficial influence of whole-body cryotherapy on adaptive processes of vegetative nervous system.

I. Jurczak, K. Dudek, K. Jurczak, R. Irzmański – Impact of controlled physical exercise on NT-proBNP level and ejection fraction in patients with acute coronary disease – original paper. FP 2016; 16(3); 58-66

Abstract
Purpose. Assess the effect of a controlled physical training on the level of NT-pro BNP and left ventricular ejection fraction depending on the time and type of physical exercise.
Methods. Eighty-three patients were included in the study. Two groups participated in interval training on a cycle ergometer and exercise improving general physical. Control Group participated in exercise improving general physical only. The immunoenzymatic test for qualitative determination of the NT – proBNP level and echocardiographic examination was performed in all groups.
Results. The authors observed changes in NT-proBNP level testing and echocardiographic examination. In the group I, after a 2-week training, the NT-proBNP value decreased by 13.2%. In the same group, mean EF values were significantly increased, from 51.23% to 51.95%. In the group II a 29% reduction of the NT-pro BNP level was observed. EF values were significantly increased, from 50.62% to 51.69%. As for final NT-proBNP values in the control group, a decrease of the peptide level by 3.9% was observed, compared to initial values. In the same group, a non-significant increase of the EF value was observed, from 47.06% to 47.13%
Conclusions. Findings of the studies confirm that cardiac rehabilitation decrease of the NT-proBNP level and improves LVEF in patients with acute coronary disease.
