Prognostic relevance of magnesium alterations in patients with a myocardial infarction and left ventricular dysfunction: insights from the EPHESUS trial.

Aims: Magnesium changes are common in myocardial infarction (MI) complicated with left ventricular systolic dysfunction (LVSD) and/or heart failure (HF). The relation between serum magnesium and clinical outcomes is insufficiently elucidated in this population.

Methods And Results: The EPHESUS trial randomized 6632 patients to either eplerenone or placebo.

Serum sodium and eplerenone use in patients with a myocardial infarction and left ventricular dysfunction or heart failure: insights from the EPHESUS trial.

Background: Sodium changes are common in myocardial infarction (MI) complicated with left ventricular systolic dysfunction (LVSD) and/or heart failure (HF). Sodium handling is fine-tuned in the distal nephron, were eplerenone exhibits some of its pleotropic effects. Little is known about the effect of eplerenone on serum sodium and the prognostic relevance of sodium alterations in patients with MI complicated with LVSD and/or HF.
