Silencing of the Na + /H + exchanger 1(NHE-1) prevents cardiac structural and functional remodeling induced by angiotensin II.

Chronic activation of the renin angiotensin system (RAS) favors several cardiac diseases, among which myocardial hypertrophy occupies an outstanding place. In this context, the hyperactivity of the cardiac Na+/H+ (NHE-1) exchanger plays a key role. The pathologic remodeling of the myocardium constitutes an independent risk factor for morbidity and mortality with continuously increasing healthcare cost. Therefore, the development of better therapeutic strategies emerges as highly mandatory.
