Patients with elevated CRP levels experienced higher frequencies of atrial fibrillation (57.5 vs. 41.3%, p < 0.001), hypertension (64.9 vs. 60.6%, p = 0.01), and diabetes mellitus (26.2 vs. 16.8%, p = 0.003), as well as leukocyte counts (10.46 ± 6.79 G/l vs. 9.79 vs. 3.39 G/l, p < 0.001). The gene discussed is CRP; the disease is atrial fibrillation.
