P. Reddy et Ab. Dunn, The effect of beta-blockers on health-related quality of life in patients with heart failure, PHARMACOTHE, 20(6), 2000, pp. 679-689
beta-Blockers reduce the risk of death in patients with heart failure and a
re recommended in those with stable class II or III disease despite optimal
standard therapy Health-related quality of life (HRQOL) is an increasingly
important end point in clinical trials. We reviewed all studies that deter
mined the effect of beta-blockers on HRQOL in patients with heart failure.
In these trials, HRQOL was assessed by the Quality of Life Questionnaire in
Severe Heart Failure and the Minnesota Living with Heart Failure Questionn
aire. Three of the 10 studies that used either of these instruments reporte
d significant improvements in scores. When HRQOL was determined by a single
-question global assessment, substantial improvements were observed by pati
ents and physicians in five of the seven studies that used the instrument.
Possible reasons for the lack of consistent effect on HRQOL include lack of
responsiveness of currently available instruments, incomplete data collect
ion, and true lack of effect of beta-blockers on HRQOL in these patients.
