Background: The aim of this study was to see if the CHA2DS2-VASc score (Cardiac failure or dysfunction, Hypertension, Age ≥ 75 [Doubled], Diabetes, Stroke [Doubled]—Vascular disease, Age 65–74 and Sex category [Female] score) could have potential clinical relevance in predicting the outcome of hospitalization time, need for ICU hospitalization, survival time, in-hospital mortality, and mortality at 3 and 6 months after discharge home. Materials: A retrospective analysis of 2183 patients with COVID-19 hospitalized at the COVID-19 Centre of the University Hospital in Wrocław, Poland, between February 2020 and June 2021, was performed. All medical records were collected as part of the COronavirus in LOwer Silesia—the COLOS registry project. The CHA2DS2-VASc score was applied for all subjects, and the patients were observed from admission to hospital until the day of discharge or death. Further information on patient deaths was prospectively collected following the 90 and 180 days after admission. The new risk stratification derived from differences in survival curves and long-term follow-up of our patients was obtained. Primary outcomes measured included in-hospital mortality and 3-month and 6-month all-cause mortality, whereas secondary outcomes included termination of hospitalization from causes other than death (home discharges/transfer to another facility or deterioration/referral to rehabilitation) and non-fatal adverse events during hospitalization. Results: It was shown that gender had no effect on mortality. Significantly shorter hospitalization time was observed in the group of patients with low CHA2DS2-VASc scores. Among secondary outcomes, CHA2DS2-VASc score revealed predictive value in both genders for cardiogenic (5.79% vs. 0.69%; p p p p p 2DS2-VASc score in predicting the severity of the course of COVID-19. Conclusions: Routine use of this scale in clinical practice may suggest the legitimacy of extending its application to the assessment of not only the risk of thromboembolic events in the COVID-19 cohort.
