The measurement of creatine kinase isoenzymes activities and mass in cardiac diseases

Objective:To investigate the usefulness of CK-MB activities and CK-MB mass in cardiac diseases or non-cardiac diseases.Methords:Patients with or without cardiac diseases were divided into cardiac troponin T（cTnT）negative（cTnT-） or cTnT positive（cTnT+） group. Results:in non-cardiac diseases group,there was no correlation between CK-MB and CK-MB mass（P＞0.05）,while in cardiac diseases group,CK-MB was correlated with CK-MB mass when TnT＞0.1（P＜0.01）and TnT＜0.1（P＜0.05）.Conclusion:There were both well sensitiveity to cardiac diseases on CK-MB mass and CK-MB activities;while CK-MB mass has better stability than CK-MB activities to different conditions.
