Strategies for myocardial protection in cardiac surgery are directed at the
prevention of procedure-induced ischemia/reperfusion injury as well as met
abolic resuscitation in acute ischemic syndromes. Postreperfusion myocardia
l dysfunction remains a significant clinical problem, most importantly in c
ertain high-risk patient groups. The large body of experimental evidence de
monstrating a significant role for sodium-hydrogen exchange activation in m
yocardial ischemia/reperfusion injury suggests that the ability to pharmaco
logically inhibit the exchanger presents a promising new approach to curren
t myocardial preservation techniques.
