Key result
Low-dose insulin (30 U/L) exerted significant cardioprotective effects comparable to GIK in a canine model of myocardial ischemia/reperfusion injury.
Why the study?
Does physiologically tolerable low-dose insulin reduce myocardial ischemia/reperfusion injury in a canine model?
Does physiologically tolerable low-dose insulin reduce myocardial ischemia/reperfusion injury in a canine model?
Low-dose insulin alone provides cardioprotection comparable to GIK during ischemia/reperfusion in dogs by creating metabolic postconditioning, avoiding the detrimental effects of glucose alone.

May support low-dose insulin for metabolic postconditioning in reperfusion; leaves open translation to human ischemia/reperfusion injury.
Zhang et al. (2006) studied Myocardial ischemia/reperfusion injury. Low-dose insulin vs. Vehicle, glucose-insulin-potassium (GIK), or glucose-potassium (GK) was evaluated on Cardioprotective effects (cardiac function, coronary blood flow, infarct size, and myocardial apoptosis). Low-dose insulin (30 U/L) exerted significant cardioprotective effects comparable to GIK in a canine model of myocardial ischemia/reperfusion injury.
