Epicardial adipose tissue and insulin resistance in obese subjects

Iacobellis, Gianluca, Leonetti, Frida·2005·The Journal of Clinical Endocrinology & Metabolism

Abstract

CONTEXT: Epicardial adipose tissue has been recently recognized as a source of bioactive molecules as well as free fatty acids, adiponectin, and inflammatory cytokines. Epicardial fat reflects intraabdominal visceral fat, and the echocardiographic assessment of this tissue is an easy and reliable marker of visceral adiposity. OBJECTIVE: In this study we evaluated whether epicardial adipose tissue is related to insulin sensitivity and glucose metabolism in obese subjects. PATIENTS: Thirty obese subjects (20 women and 10 men; mean age, 40.8 +/- 11.5 yr; body mass index, 43 +/- 9.1 kg/m2) were included in this study. No subject was taking drugs or had a history or evidence of metabolic, cardiovascular, respiratory, or hepatic disease. MAIN OUTCOME MEASURES: Each subject underwent a transthoracic echocardiogram to evaluate epicardial adipose tissue thickness, a euglycemic hyperinsulinemic clamp to estimate insulin sensitivity, and an oral glucose tolerance test to evaluate glucose tolerance. RESULTS: The thickness of the epicardial adipose tissue on the right ventricle varied between 4 and 17.4 mm. Echocardiographic epicardial adipose tissue was significantly correlated with whole-body glucose uptake index from the clamp and with all indices of insulin resistance and glucose intolerance measured, except the 120-min plasma glucose level after an oral glucose tolerance test. CONCLUSIONS: Our study showed that the epicardial fat is significantly related to obesity-related insulin resistance. This finding could be of potential interest in clinical practice and research of obesity-related risk stratification.

  • In non-diabetic people, impaired fasting glucose or obesity-related reduction of insulin sensitivity are associated with increased epicardial fat.

    “In non-diabetic people, impaired fasting glucose, or obesity-related reduction of insulin sensitivity, as assessed by euglycemic hyperinsulinemic clamp and other markers of insulin resistance, are associated with increased epicardial fat [19,55].”
  • EAT can be easily measured with standard ultrasound and independently reflects intra-abdominal visceral fat and myocardial triglyceride content.

    “Epicardial adipose tissue can be easily measured with standard ultrasound and independently reflects intra-abdominal visceral fat and myocardial triglyceride content [7–10].”
  • EAT is a modifiable and measurable cardiovascular risk factor that is thicker in subjects with diabetes, owing to its strong correlation with visceral adiposity and insulin resistance.

    “EAT has shown to be a modifiable and measurable cardiovascular risk factor that is thicker in subjects with diabetes, owing to its strong correlation with visceral adiposity and insulin resistance [7–9].”
  • The amount of epicardial fat parallels the amount of visceral adipose tissue and is correlated with the severity of LVH.

    “Iacobellis and colleagues (152, 155) have argued that the amount of epicardial fat parallels the amount of visceral adipose tissue and that the amount of epicardial fat is correlated with the severity of LVH.”

  • Myocardial triglyceride content is significantly increased in obese compared with normal-weight subjects.

    “One study used MRI spectroscopy to quantify triglyceride content in human myocardium and found it to be significantly increased in obese compared with normal-weight subjects (152).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
