Obesity
-
Body mass index (BMI) may not accurately or adequately reflect body composition or its role in the development of cardiovascular disease (CVD). Ectopic adipose depots may provide a more refined representation of the role of adiposity in CVD. Thus, the association of pericardial and intra-thoracic fat with coronary artery calcium (CAC) was examined. ⋯ Contrary to previous reports, pericardial fat was not associated with the presence, severity or progression of CAC. However, a significant association between intrathoracic fat and both the presence and severity of CAC was demonstrated. Studies measuring fat in the thoracic cavity may consider defining intrathoracic fat as a separate entity from pericardial fat.
