We assessed the clinical, electrocardiographic (ECG) and angiographic characteristics of patients with acute coronary syndrome, increased troponin I (cTn-I) levels and normal creatine kinase levels. ⋯ Increased cTn-I levels in the presence of rest pain and normal creatine kinase is not a spurious finding, but may actually be a marker of advanced CAD. However, some of these patients may also have nonsignificant CAD.
