Abstract

Backgrounds: Cardiac troponinis is a specific marker of myocardial injury, more spesific and sensitive than creatine kinase (CK). It has been suggested that troponin I specifity to detect myocardial injury may be greater than that of troponin T. Methods: Between September 2001- march 2002, in two hundred fifty patients, indicated for CABG troponin levels were measured. Troponin I in 125 patients, troponin T in 125 patients at 24 hours after CABG, CK and CK-MB in all patients at 6 and 24 hours were studied. After operation and at postoperative 24 hours, ECG were evaluated. ST-T segment changes, R progression, LBBB, RBBB, AF were enrolled. Results: Troponin I level was 18.52 ± 73.95 and troponin T level was 0.32 ± 0.029. Diagnosis of perioperative myocardial infarction was established in 3 patients from troponin I group and mean troponin I was 283.95 + 377.66. There was one patient with perioperative MI in troponin T group and troponinT was over 2 ng/mL. When the patients with ST segment changes, new Q waves, LBBB, RBBB,AF, aneurysmectomy an endarterectomy were excluded, troponin I level was 6.48 ± 9.38 (0.37-63.7) and troponin T level 0.24 ± 0.21 (0.01-1.4). Conclusions: Serum troponin levels are very important parameters to determine the myocardial injury. Troponin I over 6 and troponin T over 0.20 must sign the myocardial protection or surgical problems.

Özet

Amaç: Kardiyak troponin miyokard hasarım göstermede kreatin kinaz'dan (CK) daha sensitif ve spesifik bir biyokimyasal değerdir. Peroperatif miyokard infarktüsünün tanımlanmasında önemi belirlenmiş olup, troponin I troponin T'ye oranla daha spesifiktir. Çalışma koroner arter bypasstan sonra troponin I ve troponin T düzetlerini saptamak amacıyla gerçekleştirildi. Materyal ve Metod: Eylül 2001 - Mart 2002 tarihleri arasında randomize koroner arter bypass cerrahisi uygulanan 250 olguda troponin düzeyleri bakıldı. Olguların tümünde postoperatif 6. ve 24. saatlerde CK ve CK-MB, 24. saatte 125 olguda troponin I, 125 olguda troponin T düzeyleri ölçüldü. Operasyon çıkışında ve 24. saatte elektrokardiyografiler değerlendirildi. Sözü edilen ölçümlerle birlikte ST- T değişiklikleri, R progresyonu, LBBB , RBBB, atriyal fibrilasyon bulunup bulunmadığı kaydedildi. Bulgular: Troponin I 18.52 ± 73.95 (0.37- 719) ortalama değerlere sahipken, troponin T 0.32 ± 0.029 (0.01-2) olarak bulundu. Troponin I grubunda 3 olguda peroperatif MI tanısı konmuş olup troponin I ortalaması 283.95 ± 377.66'ya yükseldi. Troponin T grubunda ise l olgu peroperatuar MI geçirdi ve troponin T 2'nin üzerinde bulundu. ST segment değişikliği, Q dalgası varlığı, R progresyon bozukluğu LBBB, RBBB ve AF varlığı saptanan anevrizmektomi, endarterektomi uygulanan olgular ayrıldığında troponin 16.48 + 9.38 (0.37-63.70) troponin T 0.24 ± 0.21 (0.01-1.4) bulundu. Sonuç: Troponin miyokard hasarını belirlemede diğer parametreler kadar önemlidir. Troponin I nm 6 ve üzerine, troponin T nin 0.20 nin üzerine çıkması miyokard koruma ve cerrahi prosedürün gözden geçirilmesini düşündürmelidir.
