An Analysis of the Creatine Kinase Isoenzyme and Cardiac Troponin T Levels in a Polymyositis Patient
نویسندگان
چکیده
From an extensive model developed to interpret physiological processes we are able to show that the observed elevated creatine kinase-myoglobin (CK-MB) and serum concentration of cardiac troponin T (cTnT) values for a particular patient are associated with the inflammatory disease, polymyositis, and not myocardial injury. This highlights that caution must be exercised in using elevated CK-MB and cTnT levels as evidence for myocardial damage in patients with chronic muscle degeneration such as polymyositis.

Background: Early diagnosis and proper treatment of patient with acute coronary syndrome (ACS) and ischemic heart disease are important in determining prognosis, preventing adverse effects, and may even save lives. In this study, the level of pregnancy-associated plasma protein-A (PAPP-A) in ACS patients was compared with the control group, in addition to cardiac Troponin (cTn) and creatine kin...

Introduction: Serum levels of cardiac troponin (CTnI) and creatine kinase (CK-MB) are two indicators of cardiac cell damage. The present study aimedto investigate the effect of different volumes of a high-intensity interval training (HIIT) course on serum CTnI and CK-MB levels in cardiac patients after myocardial infarction (MI). Materials and Methods: In this semi-experimental study with prete...

The measurement of serum creatine kinase (CK), which is used widely in the diagnosis and management of polymyositis and dermatomyositis lacks both sensitivity and specificity, leading to potential problems if the serum total CK concentration is interpreted as a direct measure of muscle disease activity. Furthermore, in those cases where the total CK is raised reliance on an analysis of the CK i...
