AGT and myocardial ischemia: Evidence is now available that the formation of angiotensin (1–3, 8, 9, 12, 20) [Ang (1–7) elicited by the activation of ACE2 (39)] has beneficial effects in the heart (39, 41, 42), counteracting the harmful effects of Ang II (43) and re-establishing impulse conduction during myocardial ischemia (42) as well as after cell swelling (44).
