Abstract

BACKGROUND: Sudden cardiac death (SCD) is one of the main causes of cardiovascular mortality and accounts for 15-20% of deaths worldwide. The current stratification strategy using depressed left ventricular ejection fraction is insufficient to stratify the risk of SCD, especially in the general population. In recent years, there has been increasing evidence showing the antiarrhythmic properties of magnesium. In this systematic review, the authors aim to determine circulating magnesium as a potential risk stratification tool for SCD. METHODS: This systematic review was based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and was conducted in July 2021 with sources from Google Scholar, PubMed, Science Direct, EBSCO Medline, and ProQuest. RESULTS: A total of six studies were included in this review. Three studies conducted in the general population consistently showed lower risk of SCD in populations with high circulating magnesium. There was no association between circulating magnesium level and risk of SCD in intensive cardiac care unit (ICCU) patients, whilst the results were conflicting in congestive heart failure (CHF) patients. CONCLUSION: High circulating magnesium might have the potential to be utilized as a risk stratification tool for SCD, especially in the general population. However, further study is needed to support this evidence.

Key Findings

A total of six studies were included in this review. Three studies conducted in the general population consistently showed lower risk of SCD in populations with high circulating magnesium. There was no association between circulating magnesium level and risk of SCD in intensive cardiac care unit (ICCU) patients, whilst the results were conflicting in congestive heart failure (CHF) patients.
