The role of protein kinase C and phosphoinositide 3-kinase pathways in these effects was also examined. Methods The effect of P2Y(12) receptor inhibition by prasugrel (3-10 mg/kg, po) on infarct size after 30-min coronary artery occlusion and 120-min reperfusion or on arrhythmias after 7-min coronary occlusion and 7-min reperfusion was evaluated. Results In the control group, 31.25 +/- 3.01% of the risk zone infarcted. At both prasugrel doses, infarct size was significantly smaller than that in the control group: 5.03 +/- 0.81% for 3 mg/kg (p < 0.0001), and 8.78 +/- 2.04% for 10 mg/kg (p < 0.0001). The protein kinase C antagonist chelerythrine abolished the anti-infarct effect of prasugrel at 24.77 +/- 1.73% as did the phosphoinositide 3-kinase antagonist wortmannin abolished the anti-infarct effect of prasugrel at 27.45 +/- 2.74%. Ten mg/kg prasugrel reduced the duration of VT (p = 0.0152 vs control), and wortmannin, but not chelerythrine, reversed the effect of prasugrel on arrhythmias (p = 0.0295). Conclusion The selective P2Y(12) inhibitor prasugrel provides effective protection against myocardial infarction and ischemia-induced ventricular arrhythmias in rats. As in ischemic postconditioning, protein kinase C and phosphoinositide 3-kinase signaling pathways play a role in this protection.
