Abstract:
Myocardial ischemia and ischemia/reperfusion activate several protein kinase pathways. Protein kinase activation potentially regulates the onset of myocardial cell injury and the reduction of this injury by ischemic and pharmacologic preconditioning. The primary protein kinase pathways that are potentially activated by myocardial ischemia/reperfusion include: the MAP kinases, ERK 1/2, JNK 1/2, p38 MAPKalpha/beta; the cell survival kinase, Akt; and the sodium-hydrogen exchanger (NHE) kinase, p90RSK. The literature does not support a role for ischemia/reperfusion in the activation of the tyrosine kinases, Src and Lck, or the translocation and activation of PKC. This review will detail the role of these protein kinases in the onset of myocardial cell death by necrosis and apoptosis and the reduction of this injury by preconditioning.

Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
