Is cardioprotection by postconditioning in conscious rats limited to coronary occlusions < 45 min?
Both early and late ischemic preconditioning as well as ischemic postconditioning confer protection in conscious rats; however, unlike early preconditioning, postconditioning protects only against coronary occlusions <45 min. In the conscious rat, the cardioprotection afforded by postconditioning is limited to mild to moderate myocardial injury.
We identify moderate to poor agreement between nonprocedural and procedural outcomes of trauma triage in this population.
