Implication

Emphasizes need for myocardial quiescence during early reperfusion to enable ATP recovery; leaves open translation to clinical antiarrhythmic strategies.

Structured PICO

How do ischemia and reoxygenation affect glycolytic reactions and adenosinetriphosphate levels in heart muscle?

P
Population
Heart muscle (preclinical model, exact species not specified in abstract)
I
Intervention
15-minute myocardial ischemia followed by reperfusion with oxygenated blood (with or without 15 mmoles KCl) or deoxygenated buffered salt solution
O
Outcome
Myocardial concentrations of glycogen, hexosemonophosphate, lactic acid, and adenosinetriphosphate (ATP)surrogate

Myocardial ischemia rapidly depletes glycogen and ATP, and successful ATP recovery during reperfusion is dependent on preventing cardiac activity.
