Related to creatine phosphokinase: troponin

cre·a·tine ki·nase (CK),

an enzyme catalyzing the reversible transfer of phosphate from phosphocreatine to ADP, forming creatine and ATP; of importance in muscle contraction. Certain isozymes are elevated in plasma following myocardial infarctions.

While changes in plasma creatine phosphokinase, total protein (TP), and especially of plasma globulin, may reflect the severity of disease process in birds, and thus serve as basis for prognosis (Hawkey et al.
After 1 month of supplementation with 400 mg of Powergrape per day, scientists observed the following in athletes: Improvements in the antioxidant status of the body measured by ORAC and FRAP methods, and reduction of oxidative stress induced by physical exercise; reduction of cell damage in muscle and plasma during physical exercise, as suggested by the decrease of creatine phosphokinase (CpK), and the increase of hemoglobin concentrations in plasma; and increase of the global performance proven by a physical test.
All of this article's case study subjects had early and significantly elevated troponin, creatine phosphokinase (CPK), and CPKMB levels as well as abnormal ECG readings.
Other biochemical test results, including the creatine phosphokinase (CPK) level, were within normal limits.
RESULTS: Diet score was inversely correlated with entry values of cardiac troponin I (rho = -0.19, P < 0.001), creatine phosphokinase (rho = -0.09, P < 0.001), and creatine phosphokinase-MB (rho = -0.09, P < 0.001).
