Abstract

Objectives The aim of this study is to determine the ideal early cardiac marker (myoglobin, IMA, and copeptin) by evaluating them in cardiac troponin (cTn) negative ST segment elevation myocardial infarction (STEMI) patients. Methods STEMI patients admitted to the emergency department with chest pain were enrolled in the study. Venous blood samples were obtained a short time after admission in order to measure cTnI, creatine kinase MB (CK-MB) mass, myoglobin, ischemia modified albumin (IMA) and copeptin levels. The patients demographics and electrocardiogram (ECG) results were recorded. Results Twenty six STEMI patients were enrolled in the study. Four of them had normal cTnI levels at admission. Although copeptin levels were elevated in all of the patients, myoglobin levels were not elevated in any of them, and IMA levels were elevated in just one patient. The sensitivity of cTn increased from 84% to 100% with copeptin, and from 84% to 88% with IMA. There was no increase in cTn sensitivity with myoglobin. Conclusions Copeptin levels were elevated earlier in STEMI patients than were IMA and myoglobin. These findings support the concomitant use of cTn and copeptin in the early phase of STEMI.

Özet

AmaçBu çalışmanın amacı kardiyak troponinin (cTn) henüz yükselmediği ST yükselmeli miyokart enfarktüsü (STYME) hastalarında hangi erken be-lirteçlerin öncelikli olarak yükseldiğini saptamak ve troponin ile birlikte çalışılacak ideal erken belirteçlerin tespit edilmesine katkı sağlamaktır. Gereç ve YöntemÇalışmaya acil servise göğüs ağrısı şikayeti ile başvuran STYME hasta-ları alındı. Hastalardan başvuru anında kan örneği alınarak cTnI, kütle kreatin kinaz MB (CKMB), miyoglobin, iskemik modifiye albümin (İMA) ve copeptin değerleri ölçüldü. Ayrıca hastaların demografik verileri ve elektrokardiyogram (EKG) bulguları kaydedildi.BulgularÇalışmaya katılan 26 STYME hastasının dördünde başvuru anında cTnI normal sınırlarda idi. Bu hastaların hepsinde copeptin düzeylerinin art-mış olduğu, bir tanesinde İMA’nın yükseldiği, miyoglobin düzeylerinin ise hiçbirinde yükselmediği gözlendi. cTn’nin duyarlılığının copeptin ile birlikte kullanıldığında %84’den %100’e çıktığı, bu değerin İMA için %88’e yükseldiği ancak miyoglobinle bir artış göstermediği tespit edilmiştir.SonuçSTYME’li hastalarda erken belirteçlerden copeptin’in, İMA ve miyoglo-bine göre erken dönemde yükseldiği saptanmıştır. Bu sonuç cTn ile birlikte erken dönemde copeptin kullanımını destekler niteliktedir.
