[Morphologic basis for several myocardial metabolic disorders in the presence of respiration uncoupled from phosphorylation].
It was experimentally established that the destruction of mitochondria due to a reduction of ATP production and to their compensatory hyperfunction under energy defecit is underlying some disorders in the myocardial metabolism caused by 2,4-DNP intoxication. Energy deficit results in K+ metabolism disorders and the related acetylcholine synthesis which predisopses the changes in the cardiac function and still further increases the myocardial requirements of energy. The bio-energy disorders develop in a vicious circle manner, and when the intoxication increases, it inevitably results in energy depletion and cardiac arrest.
