When we compared the plasma CTRP3 concentrations in the AF patients according to the cardiac rhythm at admission, no significant difference was found between the patients with sinus rhythm (n = 40) and patients with AF (n = 35) (375.0 ± 110.3 ng/ml vs. 357.7 ± 99.9 ng/ml, p = 0.482). The gene discussed is C1QTNF3; the disease is atrial fibrillation.
