| In case of myocardial insufficiency and dilated cardiomyopathy, decreased expression of COX 4 results in an impaired CytOx activity. Higher enzymatic activity but equal oxygen consumption contribute to the pathophysiology of the myocardial insufficiency and appears as an indicator of oxidative stress. This kind of dysregulation should be in the focus for the development of diagnostic and therapy procedures | Myocardial insufficiency is related to reduced subunit 4 content of cytochrome c oxidase.
