  • Abstract
    Transmural differences in the heart have long been known and their importance in normal heart function emphasized. Angiotensin II is a potent effector that is regularly targeted in heart failure treatments. We used the whole-cell patch clamp to investigate the effects of angiotensin II on NaK-ATPase activity in the canine left ventricle and we show that transmural gradients in NaK-ATPase activity and contractile force are established by a corresponding gradient in angiotensin II concentration.
