[Analysis of etiology of the patients with hypertension from the People's Hospital of Xinjiang Uygur Autonomous Region].

Objective: To analyze the etiology of the patients with hypertension from the People's Hospital of Xinjiang Uigur Autonomous Region, and to investigate the distribution of hypertension in gender and different ages.

Methods: From September 1997 to December 2005, the data of 4642 patients with hypertension was retrospective studied.

Results: (1) Of all the patients, 85.24% were essential hypertension (EH) and 14.76% were secondary hypertension (SH). Higher prevalence of sleep apnea syndrome (42.92%) and anxiety (15.04%) was found in secondary hypertension. The highest prevalence of primary aldosteronism (12.12%) was found in endocrine hypertension. (2) The male patients with hypertension were more than the female ones, and the incidence of EH, sleep apnea syndrome (SAS) and primary aldosteronism was higher in male patients than female ones, and the following was less than female: anxiety, pheochromocytoma and renovascular hypertension. (3) Among the patients with SH, 21.9% were found in youth, and 9.85% in aged.

Conclusion: For the young, SH should be excluded, especially SAS and anxiety should be screened and differentiated. The highest prevalence of endocrine hypertension is primary aldosteronism in young and middle-aged male. The prevalence of pheochromocytoma in female is higher than that of male.
