The present project investigated the effect of glucose, high dose insulin and normoglycemia (GIN) therapy in patients undergoing coronary revascularization surgery. A reduction in myocardial injury as measured by cardiac troponin I was the primary end point. Cardiac function based on hemodynamics and vasoactive drug requirements as well as clinical outcome were evaluated. Hormones and metabolites and cardiac metabolism were investigated concurrently as potential mechanisms of GIN therapy. The major findings of the present study are that GIN therapy reduced post-operative myocardial injury and myocardial dysfunction leading to a decrease in major complications following coronary artery bypass grafting surgery. The mechanism of the overall improvement in cardiac function and decreased morbidity following CABG with GIN therapy is likely to be multi-factorial, but from the present results, is influenced by improved myocardial metabolism. GIN therapy is thus an effective diet for the ischemic heart.
