Objective To explore the relationship between chemerin levels and permanent atrial fibrillation in patients with hypertension. Methods A total of 160 patients with hypertension were enrolled in this study. All the patients were classified as AF(n=72) or NAF(n=88) based on the permanent atrial fibrillation or not. And 140 healthy people were collected as a control group(CON). Triglycerides, total cholesterol, low density lipoprotein cholesterol and C-reactive protein were measured by automatic biochemical detector. Serum chemerin levels were determined by enzyme-linked immunosorbent assay(ELISA). Results Serum chemerin levels were higher in AF patients than those in NAF patients(180.45±15.23 ng/mL vs 162.36±13.44 ng/mL,P<0.05). They were both higher than that of the CON patients(142.36±11.83 ng/mL,P<0.05). Multivariate logistic regression demonstrated that chemerin level was independently associated with the permanent atrial fibrillation in patients with hypertension(OR 1.112, 95% CI 1.023～1.302;P<0.001). Conclusion Serum chemerin is an independent risk factor for permanent atrial fibrillation with hypertension. The results suggest that chemerin might be a useful biomarker for predicting the permanent atrial fibrillation with hypertension.
