Background
Chronic heart failure (CHF) is a widespread disease with severe quality of life impairment and a poor prognosis. Beta-blockers are the mainstay of CHF therapy; yet they are under-prescribed and under-dosed in clinical practice. This is particularly evident in elderly patients, which may be due to a fear of side-effects or intolerance. Beta-blockers have further not been adequately tested in patients with diastolic CHF, which is particularly common in elderly patients. Finally, comparative data on the use of different beta-blockers in patients with CHF is scarce.
Aim
To compare the tolerance of bisoprolol and carvedilol in elderly patients with CHF.
Methods
CIBIS-ELD is an investigator-initiated, multi-centre, 1:1 randomised, double-blind, phase III trial comparing bisoprolol and carvedilol in patients ≥65 years with systolic or diastolic CHF. Recruitment started in April 2005 and is anticipated to be completed by April 2008 with at least 800 patients enrolled.
Perspective
This is the first large scale head to head beta-blockers trial in an elderly population with CHF. Besides determining which of two standard beta-blockers is best tolerated in elderly patients with systolic or diastolic CHF, we expect to gain further insight into the treatment of the particular population of patients with diastolic CHF.
