[Changes in the vascular wall and ischemic damages to the myocardium in reversible episodes of heart muscle ischemia].

When no anaesthetic is used, even 3-5 short-term disturbances of the myocardium supply with blood (during a few days) are enough for its initial necrosis and for damage of its vascular bed. In acute experiments on rats rutin discovers the ability to resist such damages, but on the chronic model of stenocardia in dogs its therapeutic effect can be found only under conditions of limitation of the ischemic effect by purposefully chosen complex medicinal therapy.
