Inflammatory and echocardiographic characteristics and specific treatments in comparison between patients with unclear circulatory failure, dichotomized in either probable CovHF or SHF.

Variables are shown as median and IQR 25th–75th. Statistical difference between groups was calculated using Whitney-Man-U Test. SHF: Sepsis associated heart failure. CovHF: COVID-19 associated heart failure. CRP: C-reactive protein, PCT: Procalcitonin, TNF: Tumor-Necrosis Factor, H-Score for reactive hemophagocytic syndrome estimates the risk for having reactive hemophagocytic syndrome.
