Beta blockers have been proven to have benefit in heart failure (HF) patients with regard to morbidity and mortality. However, initiation and uptitration remains a challenge in many patients. Worsening of heart failure, symptomatic hypotension and symptomatic bradycardia all limit up-titration to the target doses that have been shown to have mortality benefits (carvedilol [Coreg] 25 mg bid, metoprolol succinate [Toprol-XL] 200 mg qd) in the large clinical trials (COPERNICUS, MERIT-HF).
