Laboratory parameters of inflammation were obtained in the 24 h following surgery. aNumber (percentage)—Chi-square test or Fisher’s exact test. bMedian (1st–3rd quartile)—Mann-Whitney U-test.
ECG, electrocardiogram; HR, heart rate; bpm, beats per minute; RAD, right axis deviation; Afib, atrial fibrillation; alt, alterations; CRP, C-reactive protein; WBC, white blood cells; Neutr, neutrophils.
