  1. Guideline recommendations for screening of patients for primary aldosteronism. (Funder et al. 2016): *- Sustained BP > 150/100 mmHg without treatment, > 140/90 mmHg on 3 antihypertensive drugs or < 140/90 mmHg but requiring at least 4 antihypertensive drugs. In one study, 33.9% of patients with obstructive sleep apnea were found to have PA (Di Murro et al. 2010)
