Development of circulating antiheart antibodies as a result of coronary bypass surgery
JR Baker Jr, DJ Cohen, HD Head, JL DeShong and GM Graeber
Antiheart antibodies have been implicated as a marker of postcardiotomy
syndrome in patients undergoing coronary artery bypass. To assess the
frequency of and contributory factors in the development of antiheart
antibodies after coronary bypass procedures, 33 patients were examined for
evidence of antiheart antibodies before and for seven days after routine
coronary artery bypass operations. Overall titers of antiheart antibodies
rose in approximately 66% of the patients. However, this rise was not
accompanied by any major clinical symptoms. History of previous myocardial
infarction or myocardial injury did not correlate with a higher frequency
of development of antibodies. Antiheart antibodies appear to be a common
consequence of coronary artery bypass operations and are not routinely
associated with the development of postcardiotomy syndrome.
