Bisoprolol has been extensively studied in three large mortality trials in stable chronic heart failure (CHF) patients. The CIBIS trial enrolled 641 patients and demonstrated the good tolerability of bisoprolol in a large CHF population, without evidence for any harmful effect. The CIBIS-II study was the first large randomized, double-blind, placebo-controlled study demonstrating in 2647 patients a dramatic reduction in mortality with a beta-blocking agent in CHF patients. CIBIS-III demonstrated in 1010 patients the equivalence of 2 different therapeutic strategies in de novo CHF patients. There was no difference in morbidity and mortality between sub-groups of patients receiving first bisoprolol or enalapril. These three trials also demonstrated the good tolerability of bisoprolol fumarate. Other studies were either limited in number of patients or not randomized. However, these studies confirmed the good tolerability of bisoprolol in CHF patients, even in elderly population. Bisoprolol fumarate is a selective beta-1 receptor blocker that significantly reduced morbidity and mortality in stable CHF patients. Bisoprolol is well tolerated with few significant side effects in different large trials.Keywords: bisoprolol, chronic heart failure, beta-blocker
