  • Title: Current perspectives for AT(1)-receptor blockers in the management of heart failure.
    Author: Swedberg K.
    Journal: J Hum Hypertens; 2002 Aug; 16 Suppl 3():S47-51. PubMed ID: 12140728.
    Abstract:
    Despite improvements in therapy, long-term mortality remains high in patients with heart failure and thus there remains a need for new treatment strategies to reduce the burden of mortality and morbidity associated with this condition. AT(1)-receptor blockers represent a rational approach to the management of heart failure, and have been shown to have beneficial effects on heart failure symptoms and exercise tolerance. However, the two outcome trials reported to date have not shown conclusive evidence of improvements in mortality. The potential benefits of AT(1)-receptor blockers in heart failure are currently being investigated in several trials. The CHARM programme (Candesartan in Heart failure - Assessment of Reduction in Mortality and morbidity) is the largest heart failure trial so far. This comprises three trials: CHARM Alternative, in patients with left ventricular dysfunction who are intolerant to ACE inhibitors; CHARM Added, in patients with left ventricular dysfunction who are also receiving ACE inhibitors; CHARM Preserved, in patients with preserved left ventricular systolic function (ejection fraction >40%). The primary end point will be a composite of cardiovascular mortality and hospitalisation for the treatment of heart failure. Other trials are currently investigating the effects of AT(1)-receptor blockers when used as an alternative or in addition to ACE inhibitors. The CHARM programme, together with other studies, should clarify the role of these agents in the management of heart failure.
