Ck Cardiac Marker. The criterion most commonly used for the diagnosis of acute. Creatine kinase is an enzyme that is often called cardiac enzyme. They can be useful in the early prediction or diagnosis of disease. Creatine kinase also known as creatine phosphokinase or phosphocreatine kinase is an enzyme expressed by various tissues and cell types.
It is a widely available marker but has low sensitivity and specificity for cardiac damage. In some noncardiac conditions such as trauma seizures hyperthyroidism and renal insufficiency ck levels may be elevated. However not all of the markers currently used are enzymes. Prior to the introduction of cardiac troponins the biochemical marker of choice for the diagnosis of acute mi was the ck mb isoenzyme. Creatine kinase ck is an enzyme found in the heart brain and skeletal muscle. Characteristics of various established cardiac markers are listed in table 8 1.
Characteristics of various established cardiac markers are listed in table 8 1.
Characteristics of various established cardiac markers are listed in table 8 1. Ck mb levels increase within 3 12 hours of onset of chest pain reach peak values within 24 hours and return to baseline after 48 72 hours. Characteristics of various established cardiac markers are listed in table 8 1. They can be useful in the early prediction or diagnosis of disease. In some noncardiac conditions such as trauma seizures hyperthyroidism and renal insufficiency ck levels may be elevated. Myocardial muscle creatine kinase ck mb is found mainly in the heart.
