Comparison of epicardial adipose tissue (EAT) thickness and anthropometric measurements in metabolic syndrome (MS) cases above and under the age of 65.

EAT is a new index of cardiac and visceral obesity. Waist circumference (WC) measurement is not fully reliable in the determination of visceral adipose tissue (VAT), especially in elderly individuals. Studies on the reflection of the intra-abdominal fat mass by the EAT mass surrounding the heart were performed. Our purpose in this study was to determine the relation between the MS criteria and EAT in MS cases and especially to compare anthropometric measures between non-geriatric patients under the age of 65, and geriatric ones over the age of 65 years. The study was performed during the years 2008 and 2009 on 120 cases; 66.7% of them were under the age of 65 and 33.3% of the cases were 65-year old or older. All of the patients were diagnosed as MS by the International Diabetes Federation (IDF) criteria. They were randomized as per the application order and included to the study. Each subject underwent transthoracic two-dimensional (2D) guided M-mode echocardiogram. We measured epicardial fat thickness on the 1/3 section close to the ventricle basis adjacent to the free wall of right ventricle from both the parasternal long axis (LA) and parasternal short axis (SA) views. Multiple regression analysis showed that WC, systolic blood pressure (SBP) and age were the strongest independent variables correlated with EAT (p<0.001). We also determined a significant correlation between low-density lipoprotein-cholesterol (LDL-C) and EAT (p<0.05). Our data show that EAT-measurement by echocardiography is an efficient method in determination of visceral adiposity and shall be taken into consideration especially when advanced age groups are in question.
