Primary aldosteronism (PA) may account for as much as 6-20% of cases of refractory hypertension referred to hypertension clinics. Because antihypertensive agents affect the physiologic renin-angiotensin-aldosterone system, screening diagnostic tests for PA are generally performed after antihypertensive agents are discontinued. However, such tests can be dangerous for patients with severe hypertension or other cardiovascular complications. However, a reliable cutoff value for the aldosterone-to-renin ratio (ARR) has not been established, especially for Asians, including the Japanese.
