Protection of the ischemic and reperfused myocardium by sodium-hydrogen exchange inhibitor / 中国药理学通报

ABSTRACT

During ischemia, the intracellular acidosis stimulates the Na +/H + exchanger. The increase in intracellular sodium secondary to increased Na +/H + exchange is reversed through exchange for calcium, resulting in calcium overload of the cells and producing cell injury and necrosis. NHE1 inhibitors exert a protective effect on myocardium subject to ischemia and reperfusion via reduction of Na +/H + exchange, attenuation of intracellular calcium accumulation and other mechanisms.
