Dogma around use of β-blocker medications in patients with chronic obstructive pulmonary disease (COPD) has been to avoid using them, because they might precipitate acute exacerbations. However, COPD could be a risk factor in atherosclerotic disease progression (by causing systemic inflammation), and β-blockers lengthen survival in patients with coronary artery disease and heart failure. Additionally, meta-analysis data demonstrate that β-blockers are safe in patients with stable COPD (Cochrane Database Syst Rev 2005; 4:CD003566).
Researchers in the Netherlands followed a cohort of 2230 COPD patients for a mean of 7 years to determine whether long-term β-blocker use lengthened survival and lowered risk for COPD exacerbations. Compared with p…
