Fig. 2. Myocardial infarct size expressed as a percentage of left ventricular area at risk in dogs receiving no preconditioning stimuli (CON), celecoxib (CELE), aspirin (ASA), or acetaminophen (ACET) in the presence or absence of anesthetic preconditioning (APC), ischemic preconditioning (IPC), or pharmacologic preconditioning (PPC). * Significantly (P < 0.05) different from CON. † Significantly (P < 0.05) different from APC alone. § Significantly (P < 0.05) different from IPC alone. ¶ Significantly (P < 0.05) different from PPC alone.
