Background Atrial fibrillation(AF)is a common clinical arrhythmia characterized by high prevalence,high disability rate,and high treatment costs,severely affecting patients'quality of life.Currently,there is no large-scale epidemiological survey on the prevalence of AF in the Xinjiang Corps region.Objective To further understand the prevalence,associated risk factors,and standardized treatment status of AF in the Shihezi area of the Xinjiang Corps,this study aims to provide reliable data support for the prevention,management,and treatment of AF in this region.Methods A cross-sectional age-stratified random sampling survey was conducted from May 2021 to June 2023 among 63 079 permanent residents aged 18 years and above in 18 pastoral and agricultural groups and urban areas of the Shihezi area of the Xinjiang Corps.A questionnaire was used to collect baseline data,epidemiological information,awareness,and treatment status of AF.Patients were divided into an AF group(n=737)and a non-AF group(n=62 342).Multifactorial Logistic regression analysis was used to explore the influencing factors of AF occurrence.Results A total of 63 079 residents from the Shihezi area of the Eighth Division of the Xinjiang Corps were included,with an average age of(54.9±15.3)years.A total of 737 AF patients were identified,with a prevalence rate of 1.17%,and an age-adjusted prevalence rate of 1.12%.The awareness rate of AF in the screened population was only 1.62%(1 021/63 079),of which the awareness rate among diagnosed AF patients was 52.78%(389/737).The prevalence rates of AF in the 18-39,40-49,50-59,60-69,70-79,and≥80 years age groups were 0.05%(5/9 964),0.32%(29/9 076),0.62%(135/21 686),1.28%(151/11 810),3.05%(207/6 776),and 5.57%(210/3 767),respectively.The prevalence rates of AF in males and females were 1.60%(441/27 591)and 0.83%(296/35 488),respectively.The prevalence rates of AF among Han,Hui,Uyghur,Kazakh,and other ethnic groups were 1.20%(720/60 014),0.70%(7/1 007),0.62%(7/1 130),1.67%(2/120),and 1.41%(1/171),respectively.The prevalence rates of AF in urban and pastoral and agricultural areas were 0.79%(350/44 504)and 2.08%(387/18 575),respectively.There were statistically significant differences in age,gender,age group distribution,residential area,and education level between the AF and non-AF groups(P<0.05).The prevalence of smoking,alcohol consumption,hypertension,coronary heart disease,type 2 diabetes,hyperlipidemia,chronic heart failure,cerebrovascular diseases,valvular heart disease,chronic pulmonary disease,sleep apnea syndrome,thyroid dysfunction,peripheral vascular disease,and tumors was higher in the AF group than in the non-AF group(P<0.05).Multifactorial Logistic regression analysis showed that age,gender,alcohol consumption,hypertension,valvular heart disease,chronic heart failure,thyroid dysfunction,sleep apnea syndrome,and tumors were influencing factors for the occurrence of AF(P<0.05).There were 85 newly diagnosed cases of AF(11.53%),257 paroxysmal AF cases(34.87%),178 persistent AF cases(21.16%),and 217 permanent AF cases(29.44%);360 cases received oral anticoagulant therapy,and 23 cases underwent radiofrequency ablation or one-stop treatment for AF,with a treatment rate of 51.96%in this region.Among AF patients,the rates of standardized treatment,non-standardized treatment,and no treatment were 360 cases(48.85%),21 cases(2.85%),and 356 cases(48.30%),respectively.The standardized treatment rates for newly diagnosed AF,paroxysmal AF,persistent AF,and permanent AF were 11.11%,28.89%,24.72%,and 35.28%,respectively.There was a statistically significant difference in the standardized treatment rates among different types of AF(χ2=18.918,P=0.004).Conclusion The prevalence rate of atrial fibrillation in Shihezi area of Xinjiang Corps is basically the same as that of the whole country,and the risk factors are similar to domestic and foreign studies.However,the awareness rate of atrial fibrillation and the standardized treatment rate of atrial fibrillation in the population are obviously low,and the situation is not optimistic.
