Area of Science:

  • Cardiovascular Medicine
  • Biochemistry

Background:

  • Ischemic heart disease (IHD) remains a leading cause of mortality worldwide.
  • Magnesium plays a crucial role in cardiovascular function and energy metabolism.
  • Theoretical pathways suggest magnesium's cardioprotective effects against ischemia.

Purpose of the Study:

  • To review the existing evidence on magnesium's efficacy in managing acute myocardial infarction (MI).
  • To reconcile the theoretical benefits of magnesium with observed clinical outcomes in IHD.

Main Methods:

  • Systematic review of clinical trials and observational studies.
  • Analysis of studies evaluating magnesium supplementation or administration in patients with acute MI.
  • Assessment of study design, patient populations, and reported outcomes.

Main Results:

  • Numerous studies have investigated magnesium's role in acute MI.
  • The results from these studies are inconsistent, showing varied effects on patient outcomes.
  • Lack of definitive evidence supporting routine magnesium use in acute MI management.

Conclusions:

  • Despite theoretical plausibility, clinical evidence for magnesium's benefit in acute MI is inconclusive.
  • Further high-quality research is needed to clarify magnesium's role in ischemic heart disease.
  • Current guidelines do not recommend magnesium for routine use in acute MI.
