[|Human|] my cardiac enzyme level was already high - 220 and in a couple weeks rose to 275 - they say no heart attack, stroke - ekg is fine MRI/CAT showed nothing and heart eco cardio showed nothing. what else could cause it to rise - and what is the danger if it continues to rise?
[|AI|]  Welcome to Chat Doctor.  The rare many other reasons he is cardiac enzymes could be elevated.  If your kidneys do not clear the enzymes from your body they will be elevated. Congestive heart failure can cause your cardiac enzymes to be elevated.  If you do not take in enough oxygen especially at night, and you have like obstructive sleep apnea, this can cause your heart to be starved of oxygen and therefore leaked cardiac enzymes.  If you want heart is working very hard due to hard breathing, on infection, this can raise your cardiac enzymes.  As long as you had a full workup, which it looks like you have, I would keep an eye on it and not worry about it.  If you however started to have shortness of breath with minimal activities, then you will need to show up to a cardiologist or the emergency department for further workup. Good luck
