Well...: CK's can be mildly elevated for many reasons, often non-cardiac. Anormal troponin means you did not have tissues damage and a normal EKG does not always rule-out coronary disease. I recommend you see a cardiologist and further explore the reason for the chest pain, especially if you have any risk factors, like family history, smoking, diabetes, high blood pressure....
