Serum potassium levels and long-term post-discharge mortality in acute myocardial infarction Academic Article uri icon


  • Imbalances in potassium homeostasis are significantly associated with cardiovascular disease events and mortality [1, 2]. Data linking hypokalemia with arrhythmia and cardiac arrest in acute myocardial infarction (AMI) have led experts to recommend maintaining potassium levels between 4 and 5.5 mEq/L [2, 3] or even to administer potassium when AMI is suspected [4]. However, Goyal et al.[1] recently reported that the lowest in-hospital mortality was observed in those with postadmission serum potassium levels between 3.5 and 4.5 mEq/L. The goal of the current study was to evaluate the relationship between post- admission potassium levels and post-discharge long-term mortality among patients with AMI. In this observational study, patients who had been admitted in a tertiary medical center for AMI between 2002 and 2004 and discharged alive were studied [5]. Exclusion criteria …
