Effect of duodenal‐jejunal bypass (DJB) on cardiac function and myocardial glucose uptake. (a–e) Sequential evaluations of (a) left ventricular end diastolic diameter (LVEDD), (b) left ventricular end systolic diameter (LVESD), (c) ejection fraction (EF), (d) fractional shortening (FS) and (e) the ratio peak velocities of early filling/peak early diastolic velocities of (E/e′) at 8 weeks after surgery. (f) Result of hemodynamic measurement indicated by left ventricular end diastolic pressure (LVEDP). (g) Representative transverse axis images of the heart showing ¹⁸F‐FDG distribution in the first (g1), second (g2), and third (g3) rounds of PET scan, the yellow cross indicates the position of heart. (h) Representative three‐dimensional reconstruction of the third round of fluorine‐18 labeled fluorodeoxyglucose scan, the green square indicates the position of the heart. The first round was carried out regularly after fluorine‐18 labeled fluorodeoxyglucose injection, whereas the second round was carried out after an intravenous glucose load, and the third round was carried out after an intragastric glucose load. (i) The statistical results of standard uptake value (SUV). Data are expressed as mean ± standard deviation for n = 10 per groups. **P < 0.01 sham versus control; ^# P < 0.05, ^## P < 0.01 DJB versus sham; ^& P < 0.05, ^&& P < 0.01 DJB versus control.
