We conclude that troponin-I is a preferable prognostic marker of acute myocardial infarction in the first 48 hour because of the reverse correlation with left ventricular ejection fraction and higher specificity than that of miyoglobin.

Abstract

AIM: To evaluate the sensitivity, specificity, and kinetics of troponin-I, miyoglobin and CK-MB for determination of acute myocardial infarction and relation with prognostic indicators. MATERIAL AND METHOD: 46 patients with acute myocardial infarction (38 male, 8 female, median age 59,3±9,2 years) were included in this study. Venous blood samples were collected on admission, and at 12th, 24th and 48th hours after thrombolitic therapy. Coronary angiography was performed to all patients. RESULTS: Sensitivity and specificity on admission, 12th, 24th and 48th hours were calculated as %59.6-100, % 91.5-100, % 83-100, % 53.3-100 for total CK-MB, %94.9-58.3, % 100-94.1, % 100-100, % 100-69.6 for troponin-I and %97.3-57.7, % 100-69.6, % 100-45.7, % 100-32 for miyoglobin, respectively. There was a reverse correlation between troponin-I peak levels and left ventricular ejection fraction(r=0,42, p=0,005). CONCLUSION: Although the specificity of the total CK-MB was found to be higher than those of other markers in first 48 hours of acute myocardial infarction, the sensitivities of miyglobin and troponin-I were found to be highest in all stages of acute myocardial infarction. We conclude that troponin-I is a preferable prognostic marker of acute myocardial infarction in the first 48 hour because of the reverse correlation with left ventricular ejection fraction and higher specificity than that of miyoglobin.

Özet

AMAÇ: Akut miyokard infarktüsünde miyokard hasarının göstergelerinden olan troponin-I, miyoglobin ve CK-MB enzimlerinin duyarlılık, özgüllük ve kinetiği ile bu parametrelerin koroner arter hastalığının şiddeti, risk faktörleri ve komplikasyonlarla olan bağıntılarını araştırmayı amaçladık. GEREÇ VE YÖNTEM: Akut miyokard infarktüsü tanısıyla yatırılan 46 (38 erkek, 8 kadın, yaş ortalaması 59,3±9,2 yıl) hastadan kabulde, trombolitik tedaviden 90 dk sonra, 12., 24. ve 48. saatlerde venöz kan örnekleri alınarak total CK-MB, troponin I ve miyoglobin ölçümleri yapıldı. Tüm hastalara koroner angiografi yapıldı. BULGULAR: Kabulde, 12., 24. ve 48. saatlerde duyarlılık ve özgüllük değerleri sırasıyla total CK-MB için %59.6-100, % 91.5-100, % 83-100, % 53.3-100, troponin-I için %94.9-58.3, % 100-94.1, % 100-100, % 100-69.6 ve miyoglobin için %97.3-57.7, % 100-69.6, % 100-45.7, % 100-32 olarak hesaplandı. troponin-I piki ile sol ventr i kül ejeksiyon fraksiyonu arasında negatif korelasyon mevcuttu (r=0,42, p=0,005). SONUÇ: Akut miyokard infarktüsünün ilk 48 saatinde özgüllüğü en yüksek olan göstergenin total CK-MB, duyarlılığı en yüksek olanın ise miyoglobin ile troponin-I olduğu saptanmıştır. Sol ventrikül ejeksiyon fraksiyonuyla olan negatif korelasyonu ve miyoglobinden daha özgül olması nedeniyle troponin-I'nın ilk 48 saatte gelen hastaların prognostik değerlendiriminde tercih edilebileceğini düşünmekteyiz.
