[Effects of beta 1-adrenoblocker bisoprolol on endothelial dysfunction in patients with stable angina pectoris in combination with chronic obstructive pulmonary disease].

ABSTRACT

AIM: To study effects of a cardioselective beta-adrenoblocker bisoprolol on vascular wall endothelium and external respiration function in stable angina of effort combined with chronic obstructive pulmonary disease (COPD). MATERIAL AND METHODS: Endothelial function and external respiration were studied before and after 4-week treatment with bisoprolol in 36 patients with stable angina and COPD using assessment of endothelium-dependent vasodilatation (EDVD) and concentrations of nitric oxide metabolites. RESULTS: Significant improvement of endothelial function was achieved due to bisoprolol 4-week treatment which did not affect external respiration function. CONCLUSION: Bisoprolol is effective and safe drug in the treatment of stable angina combined with COPD. It can noticeably improve endothelial function.
