Screening for primary aldosteronism in primary care

Primary aldosteronism (PA) is common among patients with hypokalemia and hypertension. Patients with PA are at an increased risk of chronic disease if undiagnosed or untreated. Expert consensus recommends screening for PA in high-risk populations. Most antihypertensive medications can be continued during the work-up for PA. An elevated aldosterone-to-renin ratio is suggestive of PA.
