Effect of drug therapy for heart failure on quality of life.
Symptomatic heart failure interferes with a patient's quality of life (QOL) by limiting his or her ability to perform physical tasks and daily activities and by lowering his or her sense of psychological well-being. Therefore, in addition to decreasing mortality and morbidity, improving QOL should be an important goal when selecting pharmacotherapy. QOL questionnaires, both generic and disease specific, are used widely, but in randomized controlled trials of heart failure treatments, QOL has not been a routine study end point. Beta blockers and angiotensin-converting enzyme inhibitors, medications widely used in the management of heart failure and hypertension--one of the most common causes of heart failure--have been associated with negative, neutral, and modestly positive QOL effects. Angiotensin receptor blockers, combined with other therapy, including angiotensin-converting enzyme inhibitors (usually with a diuretic) and/or b blockers in heart failure, have produced improvements in QOL. Patients with hypertension whose blood pressure has been lowered have also experienced an improvement in QOL scores. With current heart failure regimens prolonging life, improving QOL becomes an even more essential end point in assessing the effectiveness of new medications, whether used alone or in combination with standard therapy.
