Do abnormal serum potassium levels increase the risk of short-term mortality in patients with acute heart failure following myocardial infarction?
In patients requiring loop diuretics for acute heart failure post-MI, serum potassium levels outside the narrow range of 3.9-4.5 mmol/L are associated with a substantially increased risk of 90-day mortality.
