ENZYMES AND DEATH

BLOOD TESTS AFTER HEART BYPASS SURGERY CAN PREDICT DEATH, ELIZABETH TRACEY REPORTS

Measuring two enzymes found in the blood when heart muscle cells are damaged or die helps predict survival in people whove had bypass surgery, a study in the Journal of the American Medical Association found. Edward Kasper, chief of clinical cardiology at Johns Hopkins, says this study points to how well blood is circulated during the surgery.

KASPER: In order to do most cardiac surgery operations you have to be on bypass so that the heart is flaccid and not moving. A machine takes over the function of the lungs and the heart. The better we can do that function, and every year we get better and better at it, the better the outcome will be for patients who have to undergo surgery, and I think this evidence of cell death, which is really what the enzymes are measuring, is directly related to the adequacy of the perfusion at the time of the operation. :33

Kasper says people should clearly select a very experienced center when having bypass to assure their best chance for a good outcome. At Johns Hopkins, Im Elizabeth Tracey.
