which directly surrounds major epicardial coronary arteries,
is known to be a rich source of free fatty acids and numbers of bioactive adipocytokines that plays important role in the development of atherosclerosis.
Multi-detector computed tomography (MDCT) allows simultaneous assessment of coronary artery calcium,
coronary artery stenosis,
coronary plaque characteristics,
and also epicardial fat volume (EFV),
without increased radiation exposure nor additional cost.
Although several studies using MDCT have shown a relationship between EFV and coronary artery calcium,
it is unknown whether elevated EFV...
Methods and Materials
We retrospectively reviewed clinical and imaging data of 87 patients with coronary artery calcification identified during either baseline or follow-up cardiac MDCT examinations.
Clinical cardiovascular risk factors were extracted by medical record review at the times of cardiac MDCT examinations.
The 10-year CHD risk based on the Framingham risk score was calculated for each patient.
Image acquisition was performed using a Brilliance 64-slice CT scanner (Philips Medical Systems,
The Netherlands) or a dual source 128-slice CT (Somatom Definition FLASH; Siemens Healthcare,
Patient characteristics in baseline are listed in Table 1.

There was no significant association between EFVi andcoronary calcium score.
Changes in the coronary calcium score are not accompanied by changes in EFVi.
Baseline EFVi does not predict rapid progression of calcium score.
