ABSTRACT
BACKGROUND: COVID-19 is associated with vascular thrombosis in critical patients. However, warfarin has not been adequately studied in patients with COVID-19. This study aimed to evaluate whether the use of warfarin, a potent oral anticoagulant, was of clinical benefit in patients with COVID-19. METHODS: This was a retrospective cohort study of COVID-19 patients diagnosed at 3 different centers in Turkey between April 2020 and April 2021. Patients were grouped by whether they were taking warfarin or not. Propensity score matching analysis was used to compare the dif ferences between the groups in mortality, hospitalization, and admission to the intensive care unit. RESULTS: A propensity score analysis was performed on 128 patients in the warfarin group and 372 patients in the control group. After matching, 84 pairs of patients were compared. The patients in the control group were more likely to be admitted to the intensive care unit (33.3% vs. 14.3%, respectively; P=.007) and had longer hospital stays than the warfarin group (7.1 vs. 14.1 days; P=.005). The warfarin group had a lower death rate compared to the control group (7.1% vs. 27.4%, respectively; P=.001), and surviving patients were sig nificantly more likely to be in the warfarin group than the control group (56.1% vs. 20.7%, respectively; P=.001). In patients on warfarin, there was a lower incidence of in-hospital death (log-rank test P=.005). CONCLUSIONS: Warfarin therapy could provide clinical benefits in patients with COVID-19. The current data highlight the importance of potent anticoagulation in the treatment of COVID-19.

PURPOSE: Although coronavirus disease 2019 (COVID-19) primarily affects the pulmonary system, the involvement of the heart has become a well-known issue. Pulmonary CT plays an additive role in the diagnosis and prognosis of the disease. We aimed to investigate the association of echocardiographic indices with pulmonary CT scores and mortality in COVID-19 patients. MATERIALS AND METHODS: A total of 123 patients diagnosed with COVID-19 were included in this study. The British Society of Thoracic Imaging (BSTI) score and echocardiographic parameters were calculated, and echocardiographic indices were compared between BSTI score grades. RESULTS: During in-hospital follow-up, 36 of 123 patients (29.3%) had died. BSTI score, IVS, LVPWd, RV mid-diameter, RV basal diameter, RV longitudinal diameter, sPAP, and RVMPI were higher, and RVFAC, TAPSE, and RVS were lower in the non-survivor group than in the survivor group. There were statistically significant changes between BSTI scores in terms of LVPWd, RV mid diameter, RV basal diameter, RV longitudinal diameter, sPAP, RVFAC, RVMPI, and TAPSE. BSTI score was positively correlated with sPAP and RV basal diameter and negatively correlated with TAPSE and RVFAC. Multivariate logistic regression analysis demonstrated that sPAP (OR â= â1.071, p â= â0.002) and RV basal diameter (OR â= â1.184, p â= â0.005) were independent predictors of high BSTI scores (grade 4 and 5). Furthermore, age, sPAP, and a high BSTI score (grade 5) were independent predictors of in-hospital mortality in COVID-19 patients. CONCLUSION: Echocardiographic indices were correlated with BSTI scores, and patients with higher BSTI scores had more cardiac involvement in COVID-19.
