Overview
If left untreated, hypoaldosteronism leads to hyperkalemia which can alter the function of cardiac conduction pathways. Depending upon the severity of hypoaldosteronism, hyperkalemia can be a life threatening condition. When serum potassium rises above ≥ 9 mEq/L, hyperkalemia may lead to ventricular fibrillation, PEA and even cardiac arrest. Common complications of hypoaldosteronism include hyperkalemia, metabolic acidosis, hypotension, hypovolemia and hyponatremia. Depending on the extent of the hyperkalemia and underlying renal or adrenal condition at the time of diagnosis, the prognosis of hypoaldosteronism may vary. Prognosis of hypoaldosteronism is generally good for patients who receive treatment.
Natural History, Complications, and Prognosis
Natural History
- If left untreated, hypoaldosteronism can progress to hyperkalemia and hyponatremia with hypo or hyper volemia.[1][2]
Prognosis
- Depending on the extent of the hyperkalemia and underlying renal or adrenal condition at the time of diagnosis, the prognosis of hypoaldosteronism may vary.[3][4][5]
- Prognosis is generally good for patients of hypoaldosteronism who receive treatment.
- Untreated patients risk having hyperkalemia which is associated with cardiac arrhythmias that can be fatal.
- Patient having underlying renal insufficiency or diabetic nephropathy generally progresses to end stage stage renal disease. Drugs such as ACEi and ARBs which are the mainstay of treatment with diabetes and renal dysfunction are avoided in hypoaldosteronism since these may lead to hyperkalemia.
