đ Featured Research Articles
Article 1: Serum magnesium and outcomes in heart failure with reduced ejection fraction: the GALACTIC-HF trial.
Journal: European heart journal
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40886161
Summary: The GALACTIC-Heart Failure trial, a randomized controlled trial investigating omecamtiv mecarbil versus placebo in heart failure patients with left ventricular ejection fraction of thirty-five percent or less, was used to assess the prognostic significance of serum magnesium concentrations. The study found that both low and high magnesium levels were associated with an increased risk of the primary outcome, a composite of cardiovascular death or heart failure events. These findings suggest that maintaining optimal serum magnesium concentrations may be important for improving outcomes in patients with heart failure with reduced ejection fraction.
