Abstract

Background: In this study, we aimed to investigate the effectsof thiol-disulfide homeostasis in patients undergoing on-pumpcoronary artery bypass grafting.Methods: Between January 2018 and October 2018, a totalof 51 patients (43 males, 8 females; mean age 61.8±8.7 years;range, 38 to 78 years) who underwent isolated on-pumpcoronary artery bypass grafting were included. Thiol-disulfidehomeostasis parameters were studied in the preoperative period(T1), 30 min after the removal of cross-clamp (T2), andpostoperative sixth h (T3). Hemodynamic parameters suchas atrial fibrillation and inotropic support requirement of thepatients were evaluated in the postoperative period.Results: There were significant differences in the measuredthiol-disulfide homeostasis parameters at different time pointsof surgery (p<0.001). Binary logistic regression analysis showedthat T2-disulfide/native thiol ratio was an independent predictorof the development of postoperative atrial fibrillation (p=0.042).There were positive and significant correlations between theT2-disulfide levels and cross-clamp time (r:0.307, p=0.029).Conclusion: Thiol-disulfide homeostasis in patients undergoingon-pump coronary artery bypass grafting changes toward todisulfide. Disulfide levels increase in parallel with prolongedischemia time. Decreased native thiol and increased disulfidelevels during ischemic period may be predictive of postoperativeatrial fibrillation.

Özet

Amaç: Bu çalışmada, on-pump koroner arter baypas greftleme yapılan hastalarda tiyol-disülfid homeostazının etkileri araştırıldı. Çalışma planı: Ocak 2018 - Ekim 2018 tarihleri arasında izole on-pump koroner arter baypas greftleme yapılan toplam 51 hasta (43 erkek, 8 kadın; ort. yaş 61.8±8.7 yıl; dağılım, 38-78 yıl) çalışmaya dahil edildi. Tiyol-disülfid homeostazı parametreleri ameliyat öncesi dönemde (T1), kros-klempin kaldırılmasından 30 dk. sonra (T2) ve ameliyat sonrası altıncı saatte (T3) çalışıldı. Ameliyat sonrası dönemde hastalarda atriyal fibrilasyon gelişimi ve inotropik ilaç gereksinimi gibi hemodinamik parametreler değerlendirildi. Bulgular: Ameliyatın farklı zaman noktalarında ölçülen tiyoldisülfid homeostazı parametreleri arasında önemli farklılıklar vardı (p<0.001). İkili lojistik regresyon analizinde T2-disülfid/ nativ tiyol oranının ameliyat sonrası atriyal fibrilasyon gelişimini öngören bağımsız bir değişken olduğu görüldü (p=0.042). T2-disülfid düzeyleri ile kros-klemp zamanı arasında pozitif ve anlamlı korelasyonlar vardı (r:0.307, p=0.029). Sonuç: On-pump koroner arter baypas greftleme yapılan hastalarda tiyol-disülfid homeostazı disülfide doğru değişmektedir. İskemi zamanının uzamasına paralel olarak disülfid düzeyleri artış gösterir. İskemik dönemde azalmış nativ tiyol ve artmış disülfid düzeyleri, ameliyat sonrası atriyal fibrilasyon gelişiminde öngördürücü olabilir.
