Previously, we demonstrated in HF‐rEF rats that hindlimb arterial injection of the TxA2‐R antagonist daltroban reduced the sympathetic and cardiovascular responses to 1 Hz dynamic skeletal muscle stretch (Butenas, Rollins, et al., 2021), but not static hindlimb skeletal muscle stretch (Butenas et al., 2020). Here, TBXA2R is linked to hydrops fetalis.
