Damage caused during heart attacks 'more severe than previously thought'

"Researchers from Michigan State University have revealed that damage caused during cardiac arrest can be more severe than previously thought. They found that cholesterol crystals released in the bloodstream during a cardiac attack or stroke can wreck artery linings much further away from the site of the attack, thus putting the patients at greater risk than previously thought. Lead researcher George Abela, a physician in Michigan State University's College of Human Medicine and chief of the Department of Medicine's cardiology section tested carotid arteries in a laboratory by injecting cholesterol crystals into them. The study was presented at the American Heart Association's Scientific Sessions meeting in New Orleans" - NewKerala
