Before During preconditioning, exposure to a non-lethal harmful stimulus triggers a body-wide increase of survival and pro-regenerative programmes that enable the organism to better withstand the deleterious effects of subsequent injuries. Heart and circulatory physiology, The discovery of preconditioning (PC) has arguably been the single most important development in the field of ischemic biology in the past 20 years.

Background Several studies have shown that both early and late effects of ischemic preconditioning (IPC) protect against myocardial injury after ischemic reperfusion. The strategy was described by Przyklenk [ 1] in 1993. Examples include ischemic preconditioning, exercise, dietary energy restriction and exposures to low doses of certain phytochemicals. 2016 Jul;6(7):160102. doi: 10.1098/rsob.160102. It is shown, for the first time, that the heart was capable of recognizing and rapidly adapting to stress, thereby becoming more resistant to subsequent injury and protecting against irreversible ischemic injury independent of an antecedent period of brief myocardial ischemia. This article reviews the pathophysiology and molecular basis of myocardial PC, with particular emphasis on the late phase of this cardioprotective adaptation. Ischemic tolerance to memory impairment associated with hippocampal neuronal damage after transient cerebral ischemia in rats.

HHS Vulnerability Disclosure, Help Disclaimer, National Library of Medicine (2005). Bowman, M. T. (1994). The NO hypothesis of late PC puts forth a comprehensive paradigm that can explain both the initiation and the mediation of this complex phenomenon, and has potential clinical reverberations, since NO donors are widely used clinically and could be used to protect the ischemic myocardium in patients.
