The long-term aim of this program of research is to improve physical and psychological health outcomes of adults with heart failure (HF). The specific aims of the randomized, controlled clinical trial are to test the effects of biofeedback-relaxation therapy in HF patients on rehospitalizations, cardiac mortality and quality of life, and on the secondary end-points of perceived control, anxiety, depression, skin temperature, plasma norepinephrine levels, and heart rate variability (HRV).
