Brief summary
To investigate the prevalence of primary aldosteronism (PA) in Chinese patients with newly diagnosed hypertension.
Detailed description
This is a nationwide sampling study. To investigate the prevalence of primary aldosteronism (PA) in Chinese patients with hypertension, we will conduct a case detection of PA in Chinese hypertensive patients from 10 centers of China (including Beijing, Chongqing, Shanghai, Guangzhou, et al.); furthermore, a case confirmation of PA (captopril challenge test and saline infusion test) will be performed if the result of case detection is positive. This study will be completed in two years.
Interventions
Plasma aldosterone concentration tests, Direct renin concentration tests
Captopril challenge test, Saline infusion test
