[Combined treatment with selective beta1 adrenoblockaders and beta2 adrenostimulants in patients with myocardial infarction associated with chronic obstructive lung diseases].

The effect of selective beta 1-adrenoblocker metoprolol, used alone or in combination with selective beta 2-adrenostimulant terbutaline, on hemodynamic and gas exchange parameters was examined in 30 patients with acute myocardial infarction (MI) and attendant chronic pulmonary obstructive diseases (CPOD). Severe gas exchange and intracardiac hemodynamic disorders, conducive to right-ventricular decompensation, were demonstrated in this category of patients. Selective beta 1-adrenoblockers can be used as part of combined treatment for MI under the monitoring of external respiration parameters in patients with mild bronchial obstruction and moderate hypoxemia, whereas in MI patients with severe respiratory insufficiency and gas exchange disorders, the treatment with beta 1-adrenoblockers can aggravate those. Combined use of metoprolol and brikanil produces a number of favorable ventilatory and hemodynamic effects, conducive to the stabilization of clinical condition in MI patients with attendant CPOD and limits the risk of complications.
