Key result
Diazoxide and ischemic preconditioning significantly reduced infarct size in isolated rabbit hearts compared to control (p < 0.05), an effect reversed by the blocker 5-HD.
Why the study?
Does modulation of the mitochondrial ATP-sensitive potassium channel affect infarct size and cardioprotection in isolated rabbit hearts subjected to ischemia-reperfusion?
Population
Isolated perfused rabbit hearts (n=28)
Comparison
Ischemic preconditioning, selective… vs Control group with no interventions
Design
Preclinical
Follow-up
1 hour of ischemia and 1 hour of reperfusion

Hypothesis-generating for mitoKATP channel targeting in cardioprotection; leaves open translation to human ischemia-reperfusion injury.
Does modulation of the mitochondrial ATP-sensitive potassium channel affect infarct size and cardioprotection in isolated rabbit hearts subjected to ischemia-reperfusion?
p-value: p=<0.05
The mitochondrial ATP-sensitive potassium channel plays a dominant role in ischemic preconditioning and represents a potential target for cardioprotection.
Nakai et al. (2001) studied Myocardial ischemia (n=28). Diazoxide or Ischemic preconditioning vs. Control (no interventions) was evaluated on Infarct size (p=<0.05). Diazoxide and ischemic preconditioning significantly reduced infarct size in isolated rabbit hearts compared to control (p < 0.05), an effect reversed by the blocker 5-HD.
