However, the suggested daily intake of potassium might be lower in patients who are prone to developing hyperkalemia such as those with impaired renal excretion of potassium from CKD, CHF, adrenal insufficiency, and medications use (angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARB), potassium-sparing diuretics, trimethoprim, cyclosporine, heparin, etc.)These patients need to be monitored frequently. This evidence concerns the gene ACE and congestive heart failure.
