Abstract

The cardiac forms of troponin I and T are new generation biochemical markers of myocardial contraction process that indicate myocardial injury. They are used for the diagnosis of acute coronary syndrome which describes myocardial injury ranging from angina, to reversible ischemia, Q-wave myocardial infarction and definite tissue necrosis, and considered as the ‘gold standard’ for the diagnosis of myocardial infarction. There are many diagnostic kits for troponin assays and reference ranges differ from each other. These discrepancies are due to reference materials used in the assay calibration and antibodies used in immunoassays. There is no consensus of troponin results because values from one assay to another can differ by a factor of ten or more. In order to compare new generation troponin T and troponin I, troponin levels of 201 patients, admitted to emergency department and hospitalized in cardiology unit of Ibn-i Sina Hospital with chest pain, were measured simultaneously. There were no discordance between troponin I and T levels in 169 (%84) patients. Discordant 32 (%16) troponin I levels were above the cut-off value. Ten of these 32 patients (%5) were found to be associated with acute coronary syndrome. Our results showed that none of these tests are superior to each other for diagnosis of acute coronary syndrome and every test should be evaluated complementary to clinical parameters.

Özet

Kardiyak troponin I ve T miyokard kasılma işleminin bileşenleri olup, miyokard zedelenmesini gösteren yeni nesil biyokimyasal belirteçlerdir. Akut koroner sendrom olarak tarif edilen anginadan, tersinir iskemi, Q dalga miyokard enfarktüsü ve bariz doku nekrozuna kadar gidebilen miyokardiyal hasarın değerlendirilmesinde kullanılır ve miyokard enfarktüsü tanısında altın standart olarak kabul edilirler. Troponin tetkikleri için çeşitli tanı kitleri mevcut olup, referans aralıklarında farklar bulunmaktadır ki, bu farklar kalibrasyon materyali ve “immunoassay”lerde kullanılan antikorlar nedeniyle ortaya çıkmaktadır. Bulunan değerler bir testten diğerine 10 katı ya da daha fazla değişebildiğinden, halen testlerin kullanımı konusunda bir görüş birliğine varılamamıştır. Son dönemde geliştirilen troponin I ve T testlerini karşılaştırmak amacıyla, hastanemiz acil servisine göğüs ağrısı ile başvuran ve kardiyoloji servisinde aynı şikayetle izlenen 201 hastada troponin I ve troponin T düzeyleri eş zamanlı olarak ölçülmüştür. Çalışma sonucunda 201 hastanın 169’unda (%84) her iki test birbiriyle uyumlu olarak bulunmuştur. Uyumsuz olduğu saptanan 32 hastada (%16) troponin I eşik değerin üstünde, troponin T ise altında olarak ölçülmüştür. Klinik bilgileri incelenen 32 hastanın 10’u (%5) akut koroner sendroma uygun olarak bulunmuştur. Sonuçlarımız her iki testin akut koroner sendrom tanısında birbirine üstünlüğünün olmadığını göstermiştir ve her test, klinik parametreleri tamamlayıcı olarak değerlendirilmelidir.
