Development of Circulating Antiheart Antibodies as a Result of Coronary Bypass Surgery

摘要

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.
