[Seasonal rearrangement of lipolytic processes and myocardial function in rabbits in hemodynamic overloading of the heart].

The interrelationship was investigated between the contractile function of the myocardium, the activity of some lipolytic enzymes in the body of rabbits and the blood content of free fatty acids under conditions of the hemodynamic heart overstrain in winter and summer. It was shown that winter is a less favourable season for the course of the above pathological process in the cardiac muscle as compared to summer.
