ABSTRACT
AIM:
Betatrophin, a recently identified circulating adipokine, affects lipid and glucose metabolism. However, association between plasma betatrophin levels and atherosclerotic diseases, such as coronary artery disease (CAD) and peripheral artery disease (PAD), has not been elucidated.METHODS:
We investigated plasma betatrophin levels in 457 patients undergoing elective coronary angiography who also had ankle-brachial index (ABI) test for PAD screening.RESULTS:
Of the 457 study patients, CAD was present in 241 patients (53%) (1-vessel [1-VD], n=99; 2-vessel [2-VD], n=71; 3-vessel disease [3-VD], n=71). Compared to 216 patients without CAD, 241 with CAD had higher betatrophin levels (median 1120 vs. 909 pg/mL, pï¼0.001). A stepwise increase in betatrophin levels was found depending on the number of ï¼50% stenotic coronary vessels 909 in CAD(-), 962 in 1-VD, 1097 in 2-VD, and 1393 pg/ml in 3-VD (pï¼0.001). Betatrophin levels correlated with the number of ï¼25% stenotic segments (r=0.24, pï¼0.001). PAD (ABIï¼0.9) was found in 41 patients (9%). Plasma betatrophin levels were also significantly higher in 41 patients with PAD than in 416 without PAD (1354 vs. 981 pg/mL, pï¼0.001). In the multivariate analysis, betatrophin levels were not a factor for CAD, but they were a significant factor for 3-VD and PAD independent of atherosclerotic risk factors. The odds ratios for 3-VD and PAD were 1.06 (95%CI=1.01-1.11) and 1.07 (95%CI=1.01-1.13) for a 100-pg/mL increase in betatrophin levels, respectively (pï¼0.05).CONCLUSION:
Plasma betatrophin levels were associated with the presence and severity of CAD and PAD, suggesting betatrophin has a role in atherosclerosis.Key words
