Associations between whole blood viscosity and SARS-CoV-2-linked death IcahnMountSinai SARSCoV2 COVID19 BloodViscosity Death Mortality
By Shanet Susan AlexJul 21 2022Reviewed by Aimee Molineux In a recent study published in the Journal of the American College of Cardiology, researchers depicted the link between coronavirus disease 2019 -associated mortality and whole blood viscosity .
According to existing reports on COVID-19 patients, WBV levels substantially heighten during the acute and recovery phases of the illness. Elevated plasma viscosity, a critical element of WBV, has also been linked to worse outcomes and thrombotic events in many studies involving acute COVID-19 patients.
Results The authors discovered that heightened estimated low-shear BV and estimated high-shear BV were associated with elevated in-hospital death among 5,621 hospitalized acute COVID-19 patients. The scientists did not find a similar correlation between WBV and COVID-19-linked mortality in the Asian population. With only 6% of COVID-19 patients hospitalized in the study coming from an Asian background, there may be a lack of enough occurrences to detect a statistical discrepancy. Furthermore, the researchers speculate that Asians may have innate defense pathways against the impact of blood hyperviscosity given that they had the lowest rate of thromboembolic disease.
