Clinical Study


This is a prospective study involving 240 hypertensive patients who underwent primary aldosteronism screening. Every patient will undertake four confirmatory tests to compare the diagnostic accuracy of the oral sodium loading test with captopril challenge testing (CCT) and Seated saline infusion test (SSST) using the fludrocortisone suppression testing (FST) as the reference standard, and to investigate the optimal cutoff of oral sodium loading test.
