Possible mechanism of anti‐inflammatory effects of low molecular weight heparin (LMWH) in patients with coronavirus disease 2019 (COVID‐19). Under conventional antiviral treatment regimens, LMWH improves hypercoagulability, inhibits IL‐6 release, and attenuates IL‐6 biological activity. It has potential antiviral effects and helps delay or block inflammatory cytokine storms. LMWH can increases the lymphocyte% in the patients. The multiple effects of LMWH encourages its application for the treatment of patients with COVID‐19. HSPG, heparin sulfate proteoglycan; SARS‐CoV‐2, severe acute respiratory syndrome‐coronavirus 2.
