Obesity Clinical Trial
Official title:
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.
In this prospective single-center study, obese patients of our clinical nutrition service,
hospitalized for nutritional assessement, are included.
All unenhanced coroCT examinations are performed on the same 64-Row CT scanner (discovery CT
750 HD scanner, GE Healthcare), using prospective ECG-triggerring. The investigation
protocol began with a standard-dose acquisition followed immediately by a low-dose
acquisition, recorded over strictly identical segments (identical first and last sections).
After these two examinations, estimated dose values are less than the diagnostic scan
reference level for a coroCT.
