Abstract

Introduction: In COVID-19 patients, the determination of the relationship between elevated D-dimer level and prognosis and the determination of thrombosis formation in the early stages of the disease are very important. The aim of this study was to investigate the prognostic role of D-dimer levels based on presentation in patients hospitalized with the diagnosis of COVID-19.

Method: The study was conducted on patients hospitalized with the diagnosis of laboratory-confirmed COVID-19 between March 11 and April 20, 2020. Patients with diseases that could have caused an increase in D-dimer were excluded from the study.

Results: The evaluation was made across a total of 1,669 patients, comprising 782 (46.9 %) females and 887 (53.1 %) males. The effects of D-dimer, CRP, ferritin, and troponin on mortality were evaluated with Enter Logistic Regression Analysis, and the model was found to be significant, with an explanatory coefficient of the model at a very good level of 91.3 %. The D-dimer scores were determined to be higher in patients who did not survive. The risk of mortality was seen to be 7.325-fold higher in cases with D-dimer measurement ≥0.5.

Conclusion: The study results showed that the D-dimer test was an independent risk factor showing mortality in COVID-19 patients (Tab. 6, Ref. 27). Text in PDF www.elis.sk Keywords: D-dimer, SARS-CoV-2, mortality.
