No Link Between Heart Surgery And Mental Decline, Study Says

A study says heart-lung machines may not be to blame for the loss in mental sharpness that many heart bypass patients suffer after surgery.

The decline had been attributed to machines used in the operating room. But Dutch researchers checked to see what happened to patients put on a different type of machine -- one that does not require stopping the heart. They found no differences in the mental decline, after a year, between users of either type of equipment.

The researchers say it's possible that the equipment they used also caused a decline. But they say anesthesia or the trauma of surgery might affect mental functioning.

The study is in the Journal of the American Medical Association.
