Angiotensin receptor blockers (ARBs) would alter balance of APs and differences would be magnified in vitro by incubation of plasma samples with recombinant human ACE2 (rhACE2). Six cats with cardiomyopathy (CM), 8 healthy cats. Prospective open label trial. Plasma equilibrium concentrations of APs were measured in healthy cats as well as in CM cats that first received no RAASi drugs (CM ) and then after 14 days of PO telmisartan (CM ). Plasma APs also were measured after in vitro incubation with rhACE2. No significant differences were found between healthy and CM groups. Concentrations of several APs, including angiotensin I (AT1) and angiotensin II (AT2) were significantly different between CM and CM groups. Incubation with rhACE2 decreased AT1 and AT2 in both groups. The geometric mean concentration of Ang1-7 was significantly higher in CM (4.9 pg/mL; 95% confidence interval [CI], 3.7-6.4 pg/mL) vs CM (3.2 pg/mL; 95% CI, 2.2-4.7 pg/mL; P = .01) and in CM  + ACE2 (5.0 pg/mL; 95% CI, 3.9-6.4 pg/mL) vs CM  + ACE2 (3.0 pg/mL; 95% CI, 1.7-5.5 pg/mL; P = .01). The most favorable theoretical AP profile that maximized Ang1-7 and other alternative APs was CM  + ACE2. Balance between traditional and alternative APs can be favorably shifted using ARBs and in vitro incubation with rhACE2. These data shed light on new AP-targeting strategies in cats with CM.
