Can frontal QRS-T angle predict mortality in patients with severe Crimean-Congo Hemorrhagic Fever?

Abstract

Purpose: This study aims to determine whether frontal QRS-T (fQRS-T) angle measurements assist in predicting prognosis in severe CCHF (Crimean-Congo Hemorrhagic Fever) patients.
 Material and Method: The study was conducted with 140 intensive care patients diagnosed with CCHF between 01.01.2012 and 2022. Demographic data and length of stay were recorded. In addition, laboratory data were recorded, including hemoglobin, troponin T, C-reactive protein, lymphocyte numbers, neutrophil, and platelet. fQRS-T angles were measured on electrocardiographic (ECG) data of the patients.
 Results: The mean fQRS-T angle was 53.9°±29.3° in non-survivors and 34.2°±17.3° in the survivors (p
