An acute sensitization of mechanically activated channels produced by contraction‐induced elevations in COX metabolites (Hayes et al., 2006; McCord et al., 2008), as well as a small role for TxA2‐R in the metaboreflex component of the EPR in HF‐rEF rats is also possible (Leal et al., 2011). Here, TBXA2R is linked to hydrops fetalis.
