CHARMed - the effects of candesartan in heart failure

The Candesartan in Heart failure: Assessment of Reduction in Mortality and mortality (CHARM) programme has already shown that candesartan is an effective alternative to angiotensin-converting enzyme (ACE) inhibitors (CHARM-Alternative), that additional benefits can be achieved by adding candesartan to ACE inhibitors (CHARM-Added), and that in patients with a preserved cardiac output there are reduced hospital admissions (CHARM-Preserved). Further recent analysis of the CHARM programme has shown that of the cardiovascular deaths, the benefit of candesartan was due to a reduction in sudden death and progressive heart failure, and that these reductions were observed in the -Alternative and -Added but not -Preserved components. Combination of the CHAR M-Alternative and -Added trials confirmed this reduction of cardiovascular deaths, and also demonstrated that candesartan reduced hospital admissions. There were also improvements in the New York Heart Association functional class of heart failure in the -Alternative and -Added, but not -Preserved, components of CHARM. The benefits of candesartan in heart failure are maintained in the presence of an ACE inhibitor and P-blocker. So far, all of the findings with candesartan in the CHARM programme have been favourable/CHARMed, although the beneficial effects in patients with a preserved cardiac output are limited
