COVID-19 pneumonia typically presents with high fever, cough, and shortness of breath and on thorax computed tomography (CT) peripheral ground glass opacities help the diagnosis. Although typical imaging findings for COVID-19 pneumonia are specified in thorax CT, these findings can be confused with other diseases. The aim of this study is to investigate the roles of radiological imaging and laboratory findings in the differential diagnosis of COVID-19 pneumonia and acute heart failure (AHF).
In the present study, 74 patients who admitted to the emergency department with respiratory distress during the pandemic period and received a diagnosis of COVID-19 pneumonia and AHF were included. Laboratory data and radiological findings of the patients, at the time of admission, were evaluated.
On admission, there was no difference in age, gender between two groups. However, COVID-19 exposure history was found significantly higher in COVID-19 pneumonia patients group (p<0.001). Fever, cough, and fatigue were found significantly higher in the COVID-19 pneumonia patients group (p<0.001). There was difference of lesions distribution between the two groups, centrally distributed lesions were found significantly higher in acute heart failure patients (p<0.001). Pleural effusion and cardiomegaly were found significantly higher in AHF patients (p<0.001, p<0.001). Counts of the white blood cells and lymphocytes were found significantly lower in COVID-19 pneumonia patients (p= 0.003, p= 0.009). COVID-19 pneumonia patients had significantly higher levels of CRP, ferritin, LDH and CK compared with AHF patients (p<0.001, p<0.001, p= 0.002, p= 0.013). However the level of NT-proBNP was found significantly higher in the AHF patients group (p<0.001).
We believe that laboratory data and thorax CT findings can provide beneficial clinical information in differentiating COVID-19 pneumonia from AHF during the pandemic.
