Swedish scientists say they've identified the genes that may protect against the development of the artery-blocking disease known as atherosclerosis. Bad cholesterol can build up in the blood and cause atherosclerosis, which is a major risk factor for heart attack and stroke. But researchers working with mice say they've identified a network of 37 genes that works to lower these cholesterol levels in the blood and helps reduce the plaque buildup that leads to atherosclerosis.
