Epicardial adipose tissue thickness is associated with the severity and extent of atherosclerotic coronary artery disease. We prospectively investigated whether epicardial adipose tissue thickness is related to coronary artery disease extent and complexity as denoted by Gensini and Syntax scores, and whether the thickness predicts critical disease. After performing coronary angiography in 183 patients who had angina or acute myocardial infarction, we divided them into 3 groups: normal coronary arteries, noncritical disease (>= 1 coronary lesion with < 70% stenosis), and critical disease (>= 1 coronary lesion with >= 70% stenosis). We used transthoracic echocardiography to measure epicardial adipose tissue thickness, then calculated Gensini and Syntax scores by reviewing the angiograms. Mean thicknesses were 4.3 +/- 0.9, 5.2 +/- 1.5, and 7.5 +/- 1.9 mm in patients with normal coronary arteries, noncritical disease, and critical disease, respectively (P < 0.001). At progressive thicknesses (< 5, 5-7, and > 7 mm), mean Gensini scores were 4.1 +/- 5.5, 19.8 +/- 15.6, and 64.9 +/- 32.4, and mean Syntax scores were 4.7 +/- 5.9, 16.6 +/- 8.5, and 31.7 +/- 8.7, respectively (both P < 0.001). Thickness had strong and positive correlations with both scores (Gensini, r = 0.82, P < 0.001; and Syntax, r = 0.825, P < 0.001). The cutoff thickness value to predict critical disease was 5.75 mm (area under the curve, 0.875; 95% confidence interval, 0.825-0.926; P < 0.001). Epicardial adipose tissue thickness is independently related to coronary artery disease extent and complexity as denoted by Gensini and Syntax scores, and it predicts critical coronary artery disease.
