ReviewPharmacological modulation of beta-adrenoceptor function in patients with coexisting chronic obstructive pulmonary disease and chronic heart failure.
Pharmacological modulation of beta-adrenoceptor function is one of the critical issues in the treatment of patients with concurrent chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF). A volume of published evidence sustains the role of long-acting beta(2)-agonists in the treatment of stable COPD, but beta-agonists seem to be detrimental when used for long term in CHF. beta(2)-agonists may exacerbate heart failure and, in any case, they induce adverse cardiac effects in COPD patients with pre-existing cardiovascular disease. ⋯ Although the literature is reassuring, there are currently no prospective long-term studies on the safety of beta-blockers in COPD. Therefore, although beta-blockers can be introduced in any medical setting for treating patients with concurrent COPD and CHF, it still seems appropriate to only use those beta-blockers that are more selective for the beta(1)-AR but without ISA at the lowest dose and to titrate them slowly with attention to lung function and symptoms, adding an inhaled antimuscarinic agent when bronchodilation is needed.
