To analyze etiology of hospitalized hypertensive patients in the department of hypertension from 1999 to 2008.
This retrospective study was performed to analyze the etiology of hospitalized hypertensive patients in department of hypertension and to show the distribution change of hypertension from 1999 to 2008.
(1) There were 5867 (75.1%) patients with essential hypertension and 1942 (24.9%) patients with secondary hypertension (SH). (2) The prevalence rate of SH increased significantly during the 10 years (χ(2) = 387.621, P < 0.001) and was higher in 2008 than in 1999 (39.3% vs. 9.5%, P < 0.05). The prevalence of obstructive sleep apnea syndrome (OSAS) and primary aldosteronism (PA) in 2008 increased 38.3 and 1.8 times respectively than in 1999 (χ(2) = 304.025, P < 0.001; χ(2) = 42.845, P < 0.001) and other SH remained unchanged. (3) The prevalence of PA complicated with OSAS increased significantly in recent five years (χ(2) = 26.376, P < 0.001). Incidence of OSAS was 23.9% in PA patients and incidence of PA was 6.7% in OSAS patients.
With the insights gained on hypertension mechanism and the development of new diagnostic technology, percent of diagnosed SH increased remarkably in recent years in hospitalized hypertensive patients in our department of hypertension. OSAS and PA are the leading causes of SH.
