RESUMEN
Objective To investigate the prevalence of target organ damage and analyze etiology in elderly hospitalized patients with hypertension.Methods A total of 1270 elderly inpatients aged 60 to 91 years from 2008 to 2012 were enrolled.This retrospective study was performed to analyze the etiology and the prevalence of target organ damage in hospitalized hypertensive patients.Results Among elderly hypertensive patients,secondary hypertension accounted for 14.2 ％ (180/1 270) while essential hypertension accounted for 85.8％ (1 090/1 270).In secondary hypertension,renovascular hypertension of atherosclerosis (67.8％) and primary aldosteronism (23.3％) had the higher prevalence rate.Among 1 090 hospitalized patients with essential hypertension,the prevalence of patients with ≥ 1 complications was 88.3 ％.The prevalence of cerebrovascular disease,coronary heart disease and chronic renal failure were 30.2 ％,26.7 ％ and 10.5 ％,respectively.The occurrence rate of the increased carotid intima-media thickness and left type hypertrophy were 66.6 ％ and 24.0 ％,respectively.The prevalence rate of cerebrovascular disease,coronary artery disease and chronic renal failure were increased with aging (P＜0.05).Compared with female,male patients had a higher prevalence rate of chronic renal failure (P＜0.05).Conclusions Secondary hypertension is mainly renovascular hypertension and primary aldosteronism in elderly patients with hypertension.And damage of target organ in elderly patients with primary hypertension is more common,highest with cerebral apoplexy among three target organs such as heart,brain and kidney disease.
