Gene Information

human ... CKM(1158)

Specificity

One unit will transfer 1.0 μmole of phosphate from creatine phosphate to ADP per minute at 37 °C (measured at 340 nm as one equimolar amount of NADH produced by coupled reaction).

Application

Creatine kinase MM fraction from human heart has been used in a study to investigate the importance of intraoperative and postoperative cardiac medical therapy in emergency coronary artery bypass grafting for acute myocardial infarction. Creatine kinase MM fraction from human heart has also been used in a study to investigate the circadian dependence of infarct size and left ventricular function after ST slevation myocardial infarction.

Biochem/physiol Actions

May be used as a control or calibrator in monitoring myocardial injury.

Warning

All human source materials have tested negative for HIV1, HIV2, HCV antibodies and HbsAg. No test guarantees a product to be non-infectious. Therefore, all material derived from human fluids or tissues should be considered as potentially infectious.

Unit Definition

One unit will transfer one micromole of phosphate from creatine phosphate to ADP per minute at 37 deg C.

Physical form

Lyophilized powder containing Tris-HCl, EDTA and N-acetyl cysteine.

The results of emergency coronary artery bypass grafting (CABG) for acute myocardial infarction (AMI) are less than satisfactory, and readmission for cardiac events is common. 105 patients underwent emergency CABG for AMI. We examined the long-term results of emergency CABG

This study evaluated the clinical value of myocardial contrast delayed enhancement (DE) with multidetector computed tomography (MDCT) for predicting clinical outcome after acute myocardial infarction (AMI). Although some studies have described the use of MDCT for assessment of myocardial viability

In rodents, infarct size after ischemia/reperfusion exhibits a circadian dependence on the time of coronary occlusion. It is not known if a similar circadian dependence of infarct size occurs in humans. To determine if humans exhibit a circadian dependence of
