[Ventilation and blood gas indices in myocardial infarct patients in the subacute stage].

Some indices of ventilation and blood gases were studied in 36 patients. VC, TPC were established to be reduced but RV, RV/TPC, FEV1 were increased, moderate hyperventilation, disturbed steady alveolar ventilation and moderate hypoxemia. Those changes are associated with the post-capillary alveolar hypertension and the interstitial lund changes, preconditioned by it as a result of latent cardiac insufficiency of left ventricle and the following disorder of intrapulmonary circulation. The latent cardiogenic respiratory insufficiency in the patients with clinically non-complicated course of myocardial infarction, subacute stage, is of principle importance. It is, first of all, determined by the debatable problem of the necessity of cardiotonic treatment with cardiac glycosides, of the term of motor regime and necessity of respiratory exercises.
