By identifying the early stages of thickening of the blood vessel walls that precede artery narrowing, researchers believe it may be possible to intervene and reduce the risks of heart attack and other coronary events. But, as abd-elmoniem explains: "we currently have no reliable way to non-invasively image coronary artery disease in its early stages, when the disease can be treated with lifestyle. viagra no prescription
