Abstract

Purpose: In this study, we aimed to derive significant implications by evaluating the predictive value of the troponin/CK-MB ratio, which has not been studied in previous research.

Materials and Methods: We screened all COVID-19 patients admitted to the intensive care unit(ICU) between April 2020 and September 2022. All medical records, laboratory results, and in-hospital mortality were recorded.

Results: We included 182 patients in this study. The overall correct classification rate of the proposed model was 83.0%. The Nagelkerke R² value explained 55.8% of the variance in mortality. The most predictive variable was the troponin/CK-MB ratio. An increase of 1 unit in the troponin/CK-MB ratio elevated the mortality risk by 108.90 times. A cut-off value for the troponin/CK-MB ratio, identified as the most predictive laboratory parameter, was determined to be 0.00745.

Conclusion: The Troponin/CK-MB ratio has the potential to predict in-hospital mortality in COVID-19 patients. In the management of COVID-19 in the ICU, this ratio should be used to predict poor outcomes, assisting physicians in determining the optimal follow-up care for these patients

Kötü COVID-19 Sonuçlarının Güçlü Bir Öngörücüsü: Troponin/Kreatin Kinaz-MB Oranı

Abstract

Amaç: Bu çalışmada daha önce yapılan çalışmalarda çalışılmayan troponin/CK-MB oranının öngörüsünü değerlendirerek belirleyici çıkarımlar elde etmeyi amaçladık.

Araçlar ve Yöntem: Nisan 2020 ile Eylül 2022 tarihleri arasında yoğun bakım ünitesine (YBÜ) kabul edilen tüm COVID-19 hastalarını taradık. Tüm tıbbi kayıtlar, laboratuvar sonuçları ve hastane içi ölüm kaydedildi.

Bulgular: Bu çalışmaya 182 hastayı dahil ettik. Amaçlanan modelin genel doğru sınıflandırma oranı %83.0'dır. Nagelkerke R2 değeri incelendiğinde mortalitedeki varyansın %55.8'ini açıklamaktadır. En belirleyici değişken troponin/CK-MB oranıydı. Troponin/CK-MB oranındaki 1 birimlik artış ölüm riskini 108.90 kat artırdı. Troponin/CK-MB oranı için en belirleyici laboratuvar parametresi olan kesme değeri 0.00745 olarak belirlendi.

Sonuç: Troponin/CK-MB oranının hastane içi COVID-19 mortalitesini öngörmede potansiyel bir etkisi vardır. Yoğun bakımda COVİD-19 yönetiminde kötü sonuçları tahmin etmek için Troponin/CK-MB oranı kullanılmalıdır. Dolayısıyla hekimlerin COVID-19'un optimal takibini yönetmelerine yardımcı olabilir.
