Abstract
BackgroundCardiac troponin is used as a marker for all types of myocardial infarction. MethodsAssays for high-sensitivity troponin T and I were performed before, immediately and 24h after a 40km bicycle ride in two middle aged individuals. ResultsThere was a significant increase in cardiac troponin immediately after exercise in both individuals. This was accompanied by a return to baseline levels within 24h. A CT angiogram was normal in one while the other had a significant occlusion in the mid-right coronary artery. After a stent placement, in this latter individual, there was no major increase in troponin after a second bicycle ride. ConclusionsUsing high sensitivity assays, at least one of these two subjects may have suffered a type 2 myocardial infarction had the increases in hs-cTnI were accompanied by other acceptable evidence of myocardial ischemia (symptoms, ECG, etc.).
