Key result
Ischemic preconditioning reduced myocardial infarct size to 10% of the risk area compared to 41% in controls, whereas adenosine preconditioning only reduced it to 25%.

Rabbit model suggests ischemic preconditioning exceeds adenosine effects; hypothesis-generating and leaves clinical translation open.
Does ischemic or adenosine preconditioning reduce myocardial infarct size in a rabbit model of ischemia-reperfusion?
Absolute Event Rate: 10% vs 41%
Adenosine preconditioning reduces myocardial infarct size but does not fully replicate the protective effects of ischemic preconditioning in a rabbit model.
Lasley et al. (1995) studied Myocardial infarction. Ischemic preconditioning or adenosine preconditioning vs. Control was evaluated on Myocardial infarct size (% of risk area). Ischemic preconditioning reduced myocardial infarct size to 10% of the risk area compared to 41% in controls, whereas adenosine preconditioning only reduced it to 25%.
