Low-dose aspirin might prevent or delay the onset of pre-eclampsia, including HELLP syndrome.[45]US Preventive Services Task Force.

The putative protective effect of low-dose aspirin for the prevention of pre-eclampsia has been investigated in many trials in different populations. The results of the most recent trials, including more than 30,000 women, revealed small-to-moderate reduction in the relative risk of pre-eclampsia and its complications.[47]Duley L, Meher S, Hunter KE, et al. Antiplatelet agents for preventing pre-eclampsia and its complications. Cochrane Database Syst Rev. 2019 Oct 30;2019(10):CD004659.

Inherited thrombophilias have not been established as a cause of placenta-mediated pregnancy complications, including pre-eclampsia, and anticoagulation of patients with an inherited thrombophilia to prevent pre-eclampsia is not recommended outside clinical trials.[51]Rodger MA, Paidas M, McLintock C, et al.
