The possibility that an innate mechanism of myocardial protection might be inducible in the human heart has generated considerable excitement and enthusiastic research. The potential to enhance myocardial resistance to ischemic injury in patients suffering the consequences of coronary artery disease has led to studies with more direct clinical relevance. However, in common with many other areas of clinical interest based on advances in basic scientific understanding, early enthusiasm may be disproportionate to ultimate therapeutic significance. There can be little doubt that our understanding of the mechanisms underlying the pathogenesis of ischemia-reperfusion injury has been enhanced significantly by the plethora of research stimulated by interest in endogenous myocardial protection. Direct extrapolation of observations in the laboratory to the cardiology clinic or operating theater is tempting but should be avoided. The results of recent clinical experiments that suggest that preconditioning can protect against ischemia, although encouraging, should be interpreted cautiously, with particular attention to the limitations of the end points available. A reasoned evaluation of recent research should prevent unrealistic expectations and allow improved design of future trials so that this potent adaptive phenomenon can be exploited to its maximum potential.
