Abstract

Background: In this study, we aimed to investigate the newly introduced inflammatory biomarker, neutrophil/ lymphocyte ratio, as a mortality predictor following coronary artery bypass graft (CABG) surgery. Methods: Between December 2011 and April 2012, 210 consecutive patients who underwent isolated CABG surgery in our clinic were prospectively analyzed. The baseline characteristics of the patients and preoperative neutrophil/ lymphocyte ratio were determined. The postoperative follow-up was 86.1±38.9 days. The primary endpoint was all-cause mortality. Results: Eight patients (3.8%) died of whom four deaths occurred during the first 30 days of follow-up. Univariate analyses revealed a significant difference in the preoperative neutrophil/lymphocyte ratio between the groups in which mortality was seen and the group in which no mortality was observed (p=0.037). The Receiver operating characteristic (ROC) curve showed a threshold value of 2.81 for neutrophil/lymphocyte ratio (AUC=0.72, sensitivity: 75%, specificity: 67%). Logistic regression analysis of the variables with significant differences between two groups revealed that the neutrophil/lymphocyte ratio over its threshold value was an independent predictor for mortality (OR 6.47, 95% CI 1.18-35.38, p=0.031). Conclusion: Neutrophil/lymphocyte ratio, which can be easily calculated, can be used as an independent factor in predicting early mortality following CABG surgery.

Özet

Amaç: Bu çalışmada yeni geliştirilen bir enflamatuvar parametre olan nötrofil/lenfosit oranının koroner arter bay- pas greft (KABG) cerrahisi sonrası erken dönem mortalite prediktörü olarak etkisi araştırıldı. Ça­lış­ma pla­nı: Aralık 2011 - Nisan 2012 tarihleri arasında kliniğimizde izole KABG cerrahisi yapılan ardışık 210 hasta prospektif olarak incelendi. Hastaların başlangıç özellikleri ve ameliyat öncesi nötrofil/lenfosit oranları belirlendi. Ameliyat sonrası takip süresi 86.1±38.9 gün idi. Primer sonlanım noktası, tüm-nedenlere bağlı mortalite olarak belirlendi. Bul­gu­l ar: Dört hastada ameliyat sonrası ilk 30 günde olmak üzere, toplam sekiz hastada (%3.8) mortalite görüldü. Tek değişkenli analizlerde ameliyat öncesi nötrofil/lenfosit oranı, mortalite gelişen ve gelişmeyen gruplar arasında anlamlı derecede farklı olarak saptandı (p= 0.037). Alıcı işlem karakteristikleri (ROC) eğrisinde nötrofil/lenfosit oranı için eşik değeri 2.81 olarak belir- lendi (AUC= 0.72, duyarlılık: %75, özgüllük: %67). İki grup arasında anlamlı farka sahip olan değişkenler ile yapılan lojistik regresyon analizinde ise, nötrofil/lenfosit oranı için eşik değerinin üzerinde olması mortalite için bağımsız bir prediktör olarak saptandı (OR 6.47, %95 CI 1.18-35.38, p= 0.031). So­nuç: Kolay bir şekilde hesaplanabilen nötrofil/lenfosit oranı KABG cerrahisi sonrası erken dönem mortaliteyi öngörmede bağımsız bir faktör olarak kullanılabilir.
