Restricting Blood Flow May Help Heart Bypas...(archers measured the blood levels of tro...),Health

"If you can have a noninvasive technique that can reduce by 43 percent the amount of injury sustained by the heart during bypass surgery, then you can improve the morbidity and mortality of patients," Hausenloy said.

More study is needed to see if the technique actually improves clinical outcomes, Hausenloy said. "If this can be shown, it may warrant a change in clinical practice in all patients undergoing bypass surgery," he added.

Another heart expert agrees that if this concept is workable, it could represent a major advance in heart-bypass surgery.

"Revascularization, with angioplasty or bypass surgery, carries risk of heart muscle damage, measured in the study by troponin release," said Dr. Henry Purcell, of the Royal Brompton Hospital in London, and co-author of an accompanying editorial in the journal. "We need to minimize these risks in cardiac and non-cardiac surgery."

"We clearly need more data, and the current team is designing outcome studies to see if this protection translates into clinical benefits," Purcell said.

In another report in the same issue of the journal, South Korean researchers showed that use of the painkiller celecoxib (Celebrex) after implanting a stent to open blocked arteries in people with coronary artery disease is safe and might reduce the need for repeat procedures.

Dr Hyo-Soo Kim, of Seoul National University Hospital, and colleagues studied 274 patients, all of whom were given 100 milligrams of aspirin and 75 milligrams of Plavix -- a drug designed to prevent blood clots -- a day. In addition, 136 were randomly assigned to receive celecoxib before and after the procedure.

"These data suggest that the adjunctive use of celecoxib for six months
