I had one stent about 8-years back and no heart problem otherwise. I am using cholesterols lowering medicine regularly and my cholestoral level is well below normal with medicine. I am otherwise fit and no other symptoms. Two years back I randomly get checked my cardiac enzymes and though were very high (ck-mb 11.3 & cpk 6.67). As I did not have any other heart problems I just ignored that report. Two days back I again get checked my cardiac enzyme and these were again or still very high (ck-mb 15.3 & cpk 8.75). But I have no other heart problem or symptoms. I am not sure why my cardiac enzymes are high though I have no heart problem feeling. Is my high enzymes indicate cardiac problem?
