Interval Training and Hormones in Chronic Heart Failure
Italy80 participantsStarted 2015-01
Plain-language summary
The investigators aim at investigating whether 24-week high intensity interval training might exert beneficial effects by modulating neurohormonal axis in patients with chronic heart failure (CHF). Furthermore, the effect of detraining on neurohormonal axis in CHF patients will be evaluated.
