Review Comparative Study
Are all beta-blockers the same for chronic heart failure?
beta-Adrenergic receptor blockade has been conclusively proven to increase survival and morbidity in patients with heart failure. Hospitalization rate decreases and patients feel better after receiving beta-blockers. Furthermore, this benefit is observed in a wide range of patients. ⋯ Bucindolol, an investigational beta-blocker, showed only mild improvement in survival in patients with heart failure. The beta-blockers differ regarding beta-selectivity, vasodilation properties, and perhaps other ancillary properties. At present, the importance and consequences of these differences are unknown.
