[The prevalence and distributing feature of atrial fibrillation in Xinjiang Uygur Autonomous Region Kazaks adult population].

OBJECTIVE: To investigate the prevalence and distributing feature of atrial fibrillation (AF) in Xinjiang Kazaks adult population. METHODS: Four-stage selected random samples aged 30-89 years from Tacheng, Yili and Aletai were analyzed. An epidemical study of AF was performed including inquiring medical history, recording electrocardiogram and auscultation. RESULTS: A total of 22 514 adults were surveyed. The prevalence of AF in Xinjiang Kazaks adult population was 0.37%, which was increasing with aging. The prevalence was higher in men than in women (0.5% vs 0.2%, P < 0.01). In AF patients, 23 was valvular AF. Ischemic stroke was the most frequent type and the stroke rate in the patients with AF was significantly higher than that without AF (6.0% vs 1.2%, P < 0.01). CONCLUSIONS: The prevalence of AF in Xinjiang Kazaks adult population is lower than the reported national prevalence but patients with AF in this population would not like to take the necessary medicine. Therefore, the control of AF need to be reinforced.

[Electrocardiogram Minnesota codings from 30 000 adult cases with Kazakh ethnicity in Xinjiang, China].

OBJECTIVE: To observe the abnormal Minnesota code (MC) distribution and interrelated characteristic on electrocardiograms (ECGs) of the adult Kazakh population. METHODS: Resting ECGs and blood press of randomly sampled 30 000 adult Kazakh people in three Northern regions of Xinjiang were continuously examined and analyzed, using Minnesota code recommended by WHO as the classification of ECG. RESULTS: The overall rate of abnormal ECG findings was 248.60 per thousand, and the main abnormality in males was 146.83 per thousand, compared to 157.71 per thousand in females. The prevalence rates of abnormal ST-T changes, the total arrhythmia and atrial fibrillation (AF) were 100.03 per thousand, 71.17 per thousand and 2.83 per thousand respectively. There were statistically significant differences among the main abnormities from the three regions. CONCLUSION: The ECGs abnormalities of adult Kazakh people were high. There was significant relation found between the main abnormalities and hypertension. The prevalence of AF was different from the domestically reported literature that calls for further study.
