Abstract

Cardiovascular comorbidity is common in individuals with chronic obstructive pulmonary disease (COPD). This factor interferes with pharmacological treatment. The use of β-blockers has been proposed for their known cardioprotective effects. However, due to their adverse reactions, and the risk of causing bronchospasm, there is reluctance to use them. To summarize existing evidence on the effects of β-blocker use in COPD associated with cardiovascular comorbidities in relation to disease severity, exacerbation, and mortality outcomes. EMBASE, Medline, Lilacs, Cochrane Library, and Science Direct databases were used. Observational studies that evaluated the effects of β-blockers on individuals with COPD and cardiovascular comorbidities, and related disease severity, exacerbations, or mortality outcomes were included. Studies that did not present important information about the sample and pharmacological treatment were excluded. Twenty studies were included. Relevance to patient care and clinical practice: The use of β-blockers in individuals with COPD and cardiovascular disease caused positive effects on mortality and exacerbations outcomes, compared with the results of individuals who did not use them. The severity of the disease caused a slight change in forced expiratory volume in 1 second. The odds ratio for mortality was 0.50 (95% confidence interval [CI], 0.39 to 0.63; p<0.00001), and for exacerbations, 0.76 (95% CI, 0.62 to 0.92; p=0.005), being favorable to the group that used β-blockers. Further studies are needed to study the effect of using a specific β-blocker in COPD associated with a specific cardiovascular comorbidity.
