Depends: The elevation of ck-mb is in direct proportion to the size of the infarction. The highest i personally have ever seen was about 1000 but that is very unsual. Also, ck-mb will rise as a % of the total circulating ck. Normall ck-mb is less than 1.5% of total ck.

Family history, fatty diet, smoking, high blood pressure, diabetes and other disorders can all contribute to this process. ...Read moreSee 1 more doctor answer
Is sTNT also a predictive test? So for instance it was normal yesterday are the chances small you will have an Myocardial infarction today?
No: Troponin T is a protein in cardiac muscle. If there is damage to the heart muscle, it will be released into the bloodstream, and elevated levels can be measured in the blood. It is used to document the muscle damage that occurs in a heart attack, but it is not useful to predict chances of a future heart attack, since the levels are not elevated until damage has already occurred. ...Read moreSee 1 more doctor answer
Many: The location is a major factor: left main blockage is most likely to be fatal. Proximal left anterior descending is also often fatal.
