Abstrakt: Distinct increase and then decrease in content of cyclic nucleotides was observed in dog myocardium ventricles and auricles within early periods of heart infarction (10 min-4 hrs). Within a day after ligation of artery the ratio cAMP/cGMP was considerably decreased as a result of activation of guanylate cyclase and cAMP-phosphodiesterase as well as due to a decrease in activity of adenylate cyclase. Acute ischemia of small area of the heart left ventricle caused impairment of cyclic nucleotide metabolism in all the heart muscle.
