A critical review of the most up-to-date research on purines and myocardial protection. The role of purines in reversible `myocardial stunning' and irreversible (myocardial infarction) ischemic injury, ventricular arrhythmias, and ischemic preconditioning is discussed in detail, by experts. All reviews address recent and rather controversial issues on purines and myocardial protection. Mechanisms of cardioprotection of exogenous versus endogenous purines are discussed in detail. The contribution of internationally recognized experts in the field of purines and cardiovascular physiology and in myocardial protection makes this a unique and interesting book for clinicians, basic scientists and students.
