to determine whether adding blood to a cardioplegic solution affects myocardial preservation , a randomized prospective study was carried out in 60 patients undergoing coronary revascularization to compare the effects of crystalloid potassium cardioplegics ( group c ) and potassium cardioplegic solutions to which blood has been added ( group b ) on markers of myocardial metabolism ( lactate , inorganic phosphate , base deficit release , glucose and lactate uptake , oxygen extraction ) , myocardial damage ( creatine kinase [ ck ] -mb levels ) , and cardiac performance ( cardiac index and left atrial pressure ) .
