Summary

Troponin elevation can, among others, be due to myocardial infarction, acute inflammation or structural heart disease. Formation of macrocomplexes against troponin is an underestimated cause for persistent troponin elevation. Polyethlylene glycol precipitation (PEG) can differentiate macrotroponin from real troponin elevation, but cut-off values for PEG have not been established. PEG is analyzed in patients with acute coronary syndrome undergoing invasive coronary angiography and compared to healthy marathon runners who have undergone cardiological pre-participation screening and have rested for 24 hours.

Eligibility

Age: 18 Years+Healthy volunteers accepted
Inclusion Criteria:

* Age above 18 years
* Group with acute coronary syndrome (ACS): Diagnosis of ACS (ST-segment elevation or non-ST-segment elevation myocardial infarction according to the European Society of Cardiology Guidelines 2023 with at least one measurement of high sensitive troponin I or T above the 99th percentile of reference).
* Marathon runners: Participation in a marathon following cardiological pre-participation screening and medical clearance for competition. No clinical signs of cardiovascular or structural heart disease

Exclusion Criteria:

* Patients with acute coronary syndrome: Known macrotroponin, terminal renal disease (glomerular filtration rate below 10ml per minute), diagnosis of cancer, pregnancy
* Marathon runners: Coronary artery disease, structural heart disease, diagnosis of cancer, pregnancy
