Aldosterone antagonists are the mainstay of therapy in patients with hypertension due to primary aldosteronism. However, in our experience, these patients are sometimes placed on angiotensin-converting enzyme (ACE) inhibitors in accordance with guidelines applying to the general hypertensive population. We believe this practice is inappropriate because of the inability of ACE inhibitors to lower blood pressure in patients with low renin levels. Furthermore, pleiotropic effects of ACE inhibitors are unlikely to provide significant benefits in the absence of blood pressure reduction. Therefore, ACE inhibitors should be discouraged for the majority of patients with primary aldosteronism, even in the face of renal or cardiac disease.
Key Words: aldosteronism, angiotensin-converting enzyme inhibitors, hypertension
