[Characteristics of the action of nitroglycerin on the hemodynamics of patients with ischemic heart disease in relation to the content of SH groups of the blood serum and the tolerance for physical loading].

The authors examined 196 patients who had survived myocardial infarction and 21 persons without signs of myocardial ischemia. Nitroglycerin test with subsequent control of myocardial contractility, hemodynamics and blood serum content of SH-groups indicated that the level of SH-groups could serve as a prognostic criterion of efficacy of nitrates (inverse correlation).
