[Therapeutic use of nitroglycerin in pulmonary edema and cardiac asthma in myocardial infarct patients].

The effect of sublingual medication with nitroglycerin taken in a dose of 0.5-1 mg was studied in 101 patients with myocardial infarction (77 had pulmonary edema and 34 had cardiac asthma). In patients with edema of the lungs nitroglycerin reduced dyspnoea, in some cases of cardiac asthma it arrested the attack.

[Discriminative analysis in detecting cardiac insufficiency in myocardial infarct on the basis of the values of stroke volume and blood lactic acid level].

In 203 patients with large focal and transmural myocardial infarctions the cardiac output was studied by means of the dye dilution method, as well as the content of the lactic (Barker and Summerson's technique) and pyruvic acids (Travina's technique). Along with the growth of cardiac insufficiency a fall was observed in the cardiac and stroke indices, and a growing content of the lactic and pyruvic acids and of the L/P factor. The stroke index and the blood lactate level proved to be the most informative values.
