In inguinal adipose tissue, leptin (M: 100 ± 26.3, F: 138.8 ± 21.7, AF: 142.9 ± 27.2 % M), adiponectin (M: 100 ± 21.0, F: 130.4 ± 9.5, AF: 103.7 ± 15.3 % M), IL1β (M: 100 ± 23.4, F: 59.0 ± 15.2, AF: 82.0 ± 14.7 % M), IL6 (M: 100 ± 20.8, F: 74.1 ± 16.3, AF: 94.1 ± 17.6 % M), and TNFα (M: 100 ± 13.2, F: 79.0 ± 9.1, AF: 97.9 ± 11.5 % M) mRNA levels did not differ between groups. This evidence concerns the gene TNF and atrial fibrillation.
