[Morphofunctional changes in the cardiovascular system in nitroglycerin poisoning].

The cardiovascular system was examined in acute, subacute and chronic intoxications with nitroglycerin. It was revealed that morphofunctional alterations were uniform in nature, being more demonstrable in chronic exposure during 6 months. Myocardial alterations were characterized by disturbed hemodynamics, dystrophy, focal myocarditis, changes in the activity of enzymes, and changes in the electrocardio- and rheovasographic readings. Prolonged intoxication produced more profound and stable alterations.
