From: Myocardial insufficiency is related to reduced subunit 4 content of cytochrome c oxidase
Protein content related to measurements of myocardial oxygen consumption in DCM group and control group (p = 0.643, n.s.) and simultaneous detection of CytOx activity in the presence of 20 μM reduced Cytochrome c (p < 0.001). Although the oxygen consumption rate is equal, the enzymatic activity is higher in the DCM group. The data indicates reduced efficiency in oxygen utilization as pathogenic factor for myocardial insufficiency and DCM, respectively
