Materials and methods: The serum PAPP-A, IMA, procalcitonin, and troponin I levels were measured in 100 patients with acute coronary syndrome admitted to the emergency department and 100 healthy control subjects. Results: Patients with acute coronary syndrome had significantly greater mean serum PAPP-A (patients, 10 +/- 10 mIU/L; control subjects, 6 +/- 10 mIU/L; P <= 0.001), procalcitonin (patients, 2 +/- 10 mu g/L; control subjects, 0.4 +/- 2 mu g/L; P <= 0.001), and troponin I levels (patients, 6 +/- 8 mu g/L; control subjects, 0.2 +/- 0.3 mu g/L; P <= 0.001) than control subjects. There was no difference in mean IMA levels between patients and control subjects. There were no significant correlations between PAPP-A levels and IMA, procalcitonin, or troponin I levels in patients with acute coronary syndrome. Conclusion: The PAPP-A, procalcitonin, and troponin I levels were increased in patients with acute coronary syndrome. Therefore, elevated PAPP-A and procalcitonin levels, in addition to troponin I levels, may be useful markers of myocardial injury on admission to the emergency department.en10.3906/sag-1311-55info:eu-repo/semantics/openAccessDiagnosisemergency departmentheartinfarctionPAPP-Atroponin IArticle45115916325790546Q3WOS:000347840000025Q4
