[Comparison of the blood plasma depressor prostaglandin content and the indicators of hemodynamics in dogs with experimental myocardial infarct and cardiogenic shock].
The quantitative composition of depressor prostaglandins PGE1 and PGA1 in the plasma of arterial and venous blood and blood from the great cardiac vein was studied in comparison with the values of hemodynamics in dogs with experimental myocardial infarction and cardiogenic shock. The content of prostaglandins in blood plasma was determined by the radioimmune method. The development of acute coronary insufficiency was attended with changes in the quantitative composition of the depressor PGE1 and PGA1 in the plasma of arterial and venous blood and blood from the great cardiac vein. In myocardial infarction and particularly in cardiogenic shock, intensification of PGE1 and PGA1 synthesis and an increase in the consumption of these PG by the myocardium occurred beginning with the first hours following occlusion of the coronary arteries, which suggests that PGE1 and PGA1 may probably take part in the normalization of the activity of the affected heart.
