[The lipid and phospholipid composition of the myocardium in hyperfunction caused by aortic coarctation].

It is shown that in the first 10-12 days of heart hyperfunction caused by subdiaphragmatic constriction of the aorta adaptational changes in lipid metabolism develop in the myocardium in addition to its hypertrophy. These changes are capable of leading to reduced viscosity of the myocardial membranes and activation of enzymatic processes providing for the intensified work of the heart.
