FABP4 and atrial fibrillation: Any change was detected in SAT SVC regarding AF (Figure 6A‐C), After analysing FABP4 secretion by EAT explants from 10 patients (75 ± 7 years old, BMI: 27.87 ± 3.30 kg/m2, 20% with CAD, 30% with T2DM, 70% hypertensive, 50% with HF and 40% with AF), we observed a similar secretion levels between EAT and SAT (Figure S1).
