摘要
ObjectiveTo investigate the prevalence of primary aldosteronism (PA) among participants with hypertension, evaluate the concordance of PA classification between adrenal computed tomography and adrenal venous sampling, and compare the outcomes of surgery and medication for unilateral PA.MethodsA prospective study was conducted among all inpatients with hypertension (n = 7594) at the National Center for Cardiovascular Diseases, China, from May 2016 to April 2018.ResultsOf the 7594 participants, 8.12% (n = 617) with plasma aldosterone-renin ratio ≥3.7 were possible PA cases. Three hundred sixty-seven cases with plasma aldosterone-renin ratio ≥3.7 and plasma aldosterone concentration ≥10 ng/dL were confirmed using the recumbent saline infusion test (69.20%, 182 of 263) or the captopril challenge test (66.5%, 69 of 104, P > .05). The prevalence of PA was 3.31% (n = 251). Of the 251 patients with PA, all of them had multiple comorbidities, and 49.40% (n = 124) had spontaneous hypokalemia. The concordance of PA classification between adrenal computed tomography and adrenal venous sampling was only 47.11%. The patients’ blood pressure declined to normal ranges in the adrenalectomy (85.71%, 30 of 35) and spironolactone (63.04%; 29 of 46) groups (P < .05). Furthermore, hypokalemia was normalized in the adrenalectomy (100.00%; 26 of 26) and spironolactone (94.74%; 18 of 19) groups.ConclusionIt is necessary to incorporate PA screening into routine practice for those with hypertension in the Chinese population. This will assist in ensuring that the best therapeutic schedule based on PA subtypes is devised. Additionally, as a result, it may contribute to restoring the blood pressure levels and reducing the prevalence of comorbidities in these patients with PA.
