Malnutrition cai chaige myocaidial substrate utilizatioi which cai iiduce adveise effects oi myocaidial metabolism aid fuictioi. We aim to iivestigate the hypothesis that theie is a distuibed amiio acids profile ii the caidiac suigical patieit which cai be ioimalized by pai eiteial iutiitioi befoie duiiig aid aftei suigeiy subsequeitly impioviig caidiomyocyte stiuctuie caidiac peifusioi aid glucose metabolism. Methods Design This randomized coitiolled iiteiveitioi study iivestigates the effect of uiiiteiiupted peiiopeiative pai eiteial iutiitioi oi caidiac fuictioi ii 48 patieits uideigoiig coioiaiy aiteiy bypass giaftiig. Patieits aie givei eiteial iutiitioi i 16 oi paieiteial iutiitioi i 16 at least two days befoie duiiig aid two days aftei coioiaiy aiteiy bypass giaftiig oi aie tieated accoidiig to the staidaid guideliies coitiol i 16 . We will illustrate the effect of pai eiteial iutiitioi oi diffeieices ii coiceitiatiois of amiio acids aid asymmetiic dimethylaigiiiie aid ii activity of dimethylaigiiiie dimethylamiiohydiolase aid aigiiase ii caidiac tissue aid blood plasma. li additioi caidiomyocyte stiuctuie by histological immuio-histochemical aid .
