A longitudinal study of quality of life in patients with chronic heart failure following an exercise training program.

BACKGROUND: Chronic heart failure (CHF) will become one of the greatest medical challenges during the next decades. This is especially true with regard to elderly patients. Besides medical diagnostics and drug therapy, efficient treatment of CHF must also include exercise training. AIMS: The purpose of our study was 1) to record health-related quality of life (QOL) in elderly patients with CHF and 2) to assess the efficacy of a training program, as well as to evaluate any changes detected during a six month follow-up. METHODS: In our non-randomized study, 116 patients, divided according to age into Group 1 (>70 years) and Group 2 (<70 years), took part in a 4-week training program. RESULTS: There were differences in the clinical parameters and the QOL between the older and the younger patients both after 4 weeks and at the follow-up. After six months, however, the older patients again recorded having an inferior QOL to that of the younger patients. CONCLUSION: Elderly patients can also benefit from physical exercise training, with improvement in clinical parameters and QOL. In order to maintain the subjectively improved QOL in the long term, however, continued special heart failure education and support is required.

Combined endurance and muscle strength training in female and male patients with chronic heart failure.

BACKGROUND: Exercise training has now become established practice in patients with chronic heart failure. Women are often under-represented in intervention studies compared to men. For this reason it was our aim to conduct a combined endurance and muscle strength training program to evaluate its effect on clinical performance data and health-related psychosocial factors in women and men. METHODS: One hundred and sixteen women, mean age 69 +/- 9 years, body mass index (BMI) 25.8 +/- 4.9, and 169 men, mean age 66 +/- 9 years, BMI 26.6 +/- 3.6 underwent combined endurance/resistance training. The training program lasted 29 +/- 7 days and comprised bicycle ergometer training, a 6-min walk test as a training unit and muscle strength training for the lower and upper extremities. RESULTS: Differences between women and men were found in clinical parameters. In particular, statistically significant differences were revealed between the women and men with regard to cardiopulmonary performance. Quality of life was significantly improved on discharge with regard to both physical and mental health, whereas anxiety and depression showed no significant alteration. CONCLUSION: A specialized in-hospital program for women and men combining endurance/resistance training and education is feasible. But our program revealed a very low level of cardiopulmonary performance in women. Women need to be encouraged and motivated to participate in such programs.
