5. Study Description

Brief Summary
Open-heart surgery causes injury of the heart muscle. Although this is usually mild, temporary and reversible, if it is severe it can endanger life and require additional high cost care. During surgery, techniques are used to protect the heart from injury, but these remain imperfect. This study assesses the effect of facilitating sugar metabolism (a more efficient fuel) by the heart muscle using the drug Perhexiline given before the operation. This treatment has a sound experimental basis for improving outcome. If this improvement is confirmed surgical results could be improved. The investigators will be studying heart function, heart muscle energy stores and chemicals which quantify the amount of heart muscle injury. The investigators' hypothesis is that Perhexiline will improve the protection of the heart by decreasing damage that may occur during heart surgery.
