CT Evaluation of Cardiovascular Risk Markers in Obese Patients

Obesity is a chronic metabolic disorder : it leads to coronary heart disease and early atherosclerosis. Coronary artery calcium measured by CT is known as a robust predictor to predict risk for cardiac events in symptomatic and asymptomatic individuals. Furthermore, recent studies show that other CT risk factor exists, independent of calcium scoring, such as epicardial fat, intrathoracic fat and visceral fat. The aim of this prospective study is to evaluate these new cardiovascular risk markers in obese patients, using standard dose CT and low dose CT with adaptative statistical iterative reconstruction.
