Tolerability of carvedilol in patients with heart failure and concomitant chronic obstructive pulmonary disease or asthma.

Background: A substantial proportion of the population with congestive heart failure (CHF) has concomitant airway disease. Little information exists on the tolerability of carvedilol in patients with chronic obstructive pulmonary disease (COPD). In this study, we assessed the tolerability and efficacy of carvedilol in patients with CHF and concomitant COPD or asthma.
