  • Title: Correlation between biochemical and contractile changes after myocardial ischemia and revascularization.
    Author: Puri PS.
    Journal: Recent Adv Stud Cardiac Struct Metab; 1975; 7():161-9. PubMed ID: 1226430.
    Abstract:
    Regional contractility measured as myocardial fiber shortening ceased 15-30 sec after coronary occlusion; myocardial ATP content was unaltered at this time. Contractility returned promptly if occlusion was released within 45 min. With occlusion of 1-3 hr, delayed recovery of contractility was observed 2 weeks after reperfusion; the extent of recovery diminshed with increasing period of occlusion. Concomitantly, there was parallel recovery of synthesis of ATP and creatine phosphate (CP) in reperfused myocardium.
