Plaque on CT scan is strong predictor of heart disease, worse long-term outcomes (USA)
The presence of plaque on an abdominal CT scan is a strong predictor of coronary artery disease and mortality, according to a Henry Ford Hospital study. Researchers found that patients are nearly 60 percent at risk of having coronary artery disease when the CT scan showed very high levels of abdominal aortic calcium, commonly known as plaque. High levels of the abdominal aortic calcium also increased their risk of dying, researchers say. Conversely, researchers found that the lack of abdominal aortic calcium, or AAC, was associated with a low risk of coronary artery disease, a chronic, progressive form of heart disease that results from a buildup of plaque in the arteries found on the surface of the heart. The study is being presented Sunday, March 14 at the 59th annual American College of Cardiology Scientific Sessions in Atlanta.
