Non-ADPKD patients ́ antihypertensive treatment before this present study were: angiotensin II-receptor blockers (n = 5), ACE-inhibitors (n = 4), calcium-antagonists (n = 4), loop diuretics (n = 2) and beta-adrenergic blockers (n = 3). Here, ACE is linked to autosomal dominant polycystic kidney disease.
