| Objective To investigate the current epidemiological characteristics and relevant factors of atrial fibrillation(Af) in Taiyuan, and contribute to further studies of the cause and the control strategies.Methods Using the method of cluster sampling, 9 309 permanent residents over the age of 20 were selected from 6 community committees in Taiyuan, we performed a cardiovascular epidemiological study which was mainly on Af.Results①The total crude prevalence rate of Af was 0.90%.There was an increasing trend with age , and the prevalence rate was higher in men than women (1.00%, 0.86%, p>0.05); Prevalence of Af by age distribution of the general trend was gradually increased with age increasing, from 70 to 79 age group reached the highest (2.43%), significantly higher than other age groups (p<0.001).②Non valvular Af patients was significantly higher than valve and idiopathic Af (0.73%, 0.11%, 0.06%, p<0.001); The paroxysmal, persistent and permanent Af had no significant difference in prevalence rate (0.28%, 0.30%, 0.32%, p>0.05), but the total prevalence rate of persistent and permanent Af 0.62% (chronic atrial fibrillation) was significantly higher than paroxysmal Af 0.28% (p<0.001).③Compared with paroxysmal Af and chronic Af, the usage ofβ-blockers and aspirin were more in the former than the latter (p<0.05), but digitalis was in the opposite. The ratios of patients who did not receive antiarrhythmic and antithrombotic embolization therapy were 38.1% and 41.7% respectively.Compared the two groups of statins, diuretics, and ACEI/ARB were no statistical difference significance (p>0.05). The overall results showed that more than 73% of people never taken warfarin, even aspirin, had only 25% of patients were often taken, digitalis andβblocker medication situation were far from ideal, the two drugs were only 48.7% and 28.5%.④The prevalence rate of stroke in patients with Af was significantly higher than non-AF group (10.7%, 2.1%, p<0.001). The patients with Af who accepted the treatment of antithrombotic embolization had the lower prevalence rate of stroke than the patients who did not accept the treatmet (4.1%, 20.0%, p<0.05).⑤Single independent variable logistic regression analysis showed that age, region, physical exercise, smoking, history of hypertension, diabetes, coronary heart disease, valvular history, history of heart failure, stroke history, body mass index (BMI), systolic blood pressure (SBP), pulse pressure, uric acid (UA), white blood cell (WBC), intermediate cells (MXD), neutrophils (NEUT), prothrombin time (PT) and mean corpuscular volume (MCV) were associated with Af. ⑥The relevant factors which had statistical significance(p<0.05)in univariate analysis used multivariate logistic regression analysis and the results showed that: age, the disease history of hypertension,coronary heart disease,heart failure and valvular disease,obesity and uric acid, all of the above associated with Af of OR values were 1.067, 1.700, 2.703, 3.067, 16.114, 1.698and1.068, respectively.Conclusions①The total community population prevalence of Af inTaiyuan was in a high level, the age, gender, and classification epidemiological characteristics were similar to reports at home and abroad.②The treatment of atrial fibrillation in the region was not ideal, should strengthen the control of Af.③Except age, cardiac history, smoking and other major risk factors, uric acid may also be newly discovered risk factors of Af. |
