摘要
A comparative analysis of functioning of Langendorff-isolated heart from intact rats, sham-operated rats, and rats with a model of myocardial infarction one day after ligation of the left coronary artery was carried out. No significant differences in inotropic and chronotropic functions of the heart were found in the groups of intact and sham-operated animals. In the group of rats with the myocardial infarction model, an increase in HR and a decrease in the maximum contraction and relaxation rates and left-ventricular developed pressure were shown in comparison with the groups of intact and sham-operated animals. At the same time, in the group of sham-operated animals, a decrease in coronary flow and temporal parameters of contraction was observed.
