Hello!
Welcome to Ask a Doctor service!
Regarding your concern, I would explain that CK MB is an enzyme which is mainly found in the heart and brain. But, it can also be found in other muscles.
So, a slight increase in CK MB may be also related to physical exertion, especially when troponin levels are negative.
As long as troponin levels have resulted normal and there were no ECG changes, there is no reason to worry about any heart attack or any other kind of heart damage.
These CK MB levels are borderline and they may be attributed just to physical activity or a musculoskeletal pain.
Anyway, if you experience recurrent chest pain during physical exertion, I would recommend performing an exercise cardiac stress test in order to investigate for possible coronary artery disease.
Hope you will find this answer helpful!
I remain at your disposal for any further questions whenever you need!

Thank you for the reply. Could the low blood sugar have elevated the CK-MB? There was no physical exertion at the time. My heart rate was super high and I had chest pain along with a blood sugar of 34. Of course I get tachycardia whenever my blood sugar drops.

Hello again!
Regarding your concern, I would explain that there are many studies in the medical literature, which show that low blood sugar (hypoglycemia) can induce increase CK and CK MB levels, due to muscle damage from the low glucose levels, as such low glucose levels induce stress to the muscles, which need glucose to work properly.
So, I think that high CK MB can also be explained with the low blood sugar levels.
Hope you will find this information helpful!
Wishing all the best,
