Scarborough, Keita Uchida, Maria Vogel, Noa Erlitzki, Meghana Iyer, Sai Aung Phyo, Alexey Bogush, Izhak Kehat &. WebDuring myocardial ischemia, a large reduction of tissue pH develops, and tissue pH returns to normal after reperfusion. In recent studies, we evaluated the role of pH in ischemia/reperfusion injury to cultured cardiac myocytes and perfused papillary muscles. Acidosis (pH ≤ 7.0) protected profoundly against cell death during ischemia.
