Evaluation of Patients Performed with Saline Infusion Test with a Pre-Diagnosis of Primary Hyperaldosteronism

Background: Primary hyperaldosteronism (PHA) is a primarily treatable cause of arterial hypertension characterized by low plasma renin and high aldosterone levels. The prevalence of secondary hypertension as a common endocrine cause is 5-13%. The plasma aldosterone/renin ratio (ARR) is the best available method for PHA screening. One or more confirmatory tests may be required to confirm or exclude patients' diagnoses. One frequently used confirmatory test is the saline infusion test (SİT). We aimed to screen the patients who underwent SİT with the preliminary diagnosis of PHA and to compare the results of the patients diagnosed with essential hypertension (EH) and PHA. Material and Methods: Seventy-seven patients with a history of drug-resistant hypertension or unexplained spontaneous or diuretic-induced hypokalemia or adrenal incidentaloma, or a family history of early-onset hypertension or cerebrovascular accident at a young age (0.05). Basal plasma aldosterone (p
