[Hyperbaric oxygenation and antianginal preparations: the effect of a single combined use on the functional indices of the state of the heart in patients with angina pectoris].

Using electrocardiographic technique, the effect of a single hyperbaric oxygenation session (O2 pressure 1.5 atm, duration 40 min) in combination with antianginal drugs (nifedipine--20 mg, propranolol--40 mg, nitrong--6.5 mg, orally) on central hemodynamics and myocardial contractility has been studied in 35 patients with ischemic heart disease and angina pectoris of effort, NYHA functional class II-III. It has been shown that hyperbaric oxygenation reduced the degree of indirect hemodynamic effect of nifedipine, potentiated negative chronotropic and inotropic effects of propranolol and had no impact on the degree of hemodynamic effect of depot-glycerol trinitrate.
