Insights
Candesartan, an angiotensin II receptor blocker, effectively treats hypertension and heart failure. It offers significant benefits for patients intolerant to ACE inhibitors and reduces cardiovascular events when added to ACE inhibitors.
Area of Science:
- Cardiology
- Pharmacology
- Internal Medicine
Background:
- Candesartan is a selective angiotensin II Type I (AT(1)) receptor blocker.
- It is an effective, long-acting antihypertensive agent with a favorable side effect profile.
- Emerging evidence suggests potential benefits in diabetes prevention.
Purpose of the Study:
- To evaluate the clinical value of candesartan in a broad spectrum of heart failure patients.
- To assess the efficacy of candesartan in patients unable to tolerate angiotensin-converting enzyme inhibitors (ACEIs).
- To determine the added benefit of candesartan when combined with ACEIs and its effect on heart failure hospitalization in preserved systolic function.
Main Methods:
- The CHARM (Candesartan in Heart Failure Assessment of Reduction in Mortality and Morbidity) programme comprised three prospective randomized outcome trials.
- Trials included patients with symptomatic heart failure, regardless of background therapy and ventricular function.
- Specific analyses focused on patients intolerant to ACEIs, addition of candesartan to ACEIs, and patients with preserved systolic function.
Main Results:
- Candesartan demonstrated clinical value across a wide range of symptomatic heart failure patients.
- Significant benefits were observed in patients intolerant to ACEIs, comparable to ACEI therapy.
- Adding candesartan to ACEIs (CHARM-Added) further reduced symptoms, morbidity, and cardiovascular mortality.
- Candesartan reduced heart failure hospital admissions in patients with preserved systolic function (CHARM-Preserved).
Conclusions:
- Candesartan is a valuable therapeutic option for symptomatic heart failure patients.
- It provides significant benefits for patients intolerant to ACEIs and enhances outcomes when added to ACEI therapy.
- Candesartan effectively reduces heart failure hospitalizations in patients with preserved systolic function.
Abstract:
Candesartan is a selective angiotensin II Type I (AT(1)) receptor blocker which binds tightly to, and dissociates slowly from the receptor. It is an effective, long-acting antihypertensive agent with few or no side effects, when compared to placebo in hypertension trials. Several studies indicate that candesartan might prevent diabetes. A research programme of three prospective randomised outcome trials (the CHARM [Candesartan in Heart Failure Assessment of Reduction in Mortality and Morbidity] programme) has shown that candesartan is of clinical value in a broad spectrum of patients with symptomatic heart failure, regardless of background therapy and ventricular function. There is a clear benefit of candesartan in patients unable to tolerate an angiotensin-converting enzyme inhibitor (ACEI) and this benefit is of a similar magnitude to that obtained with an ACEI. CHARM-Added shows that symptoms, morbidity and cardiovascular mortality are further reduced if an AT(1)-receptor blocker is added to an ACEI. This benefit is not only statistically significant but also clinically important. CHARM-Preserved indicate that candesartan can reduce hospital admission for heart failure in patients with preserved systolic function.
