Hearts treated with COC extract showed a significant recovery in cardiac contractile function, reduction in infarct size, and decrease in creatine kinase and lactate dehydrogenase activities.
In the study, the risk of myopathy was determined to be highest during the first 12 months of treatment; an older age, female gender, and concomitant use of a calcium channel blocker (Diltiazem in particular) were also associated with a greater risk of myopathy, which is defined as unexplained muscle weakness or pain and a serum creatine kinase level 10 times the upper limit of normal (JAMA 2004;292:2585-90).
Reduced activity of serum creatine kinase in rheumatoid arthritis: a phenomenon linked to the inflammatory response.
On admission total creatine kinase was 16907 IU/l, in keeping with the clinical picture of rhabdomyolysis.
Analyses showed elevated levels of C-reactive protein (CRP) (368 mg/L), creatine kinase (269 IU/L), and lactate dehydrogenase (1,149 IU/L).
An elevated level of serum creatine kinase, which is monitored as part of a standard cardiac panel, is the best indication of rhabdomyolysis.
These were analyzed by the Dade-Behring Stratus CS STAT near-patient instrument, which assays myoglobin; creatine kinase, myocardial bound (CK-MB); and troponin I (cTnI) from a blood sample in 15 to 20 minutes.
Measurements of strength loss, plasma creatine kinase (a muscle enzyme that is a marker for DOMS) and DOMS were made following the downhill run and all values were better for the pre-trained group.
Creatine kinase (CK-MB), in addition to helping to diagnose cardiac events, may predict a patient's risk of fatal complications during the first year after saphenous vein angioplasty, according to a report by Hong et al.
The analyst is not surprised with the creatine kinase fluctuations as patients become more active and finds it important that all biomarker/functional endpoints were improved from baseline at nine months.
DMD is caused by gene mutations that result in the absence of dystropin, a protein required to maintain muscle infrastructure, which leads to necrosis and leakage of the enzyme creatine kinase (CK; EC 2.7.3.2) (5).
