Magnesium's Mixed Blessing in Cardiac Care

Research indicates that magnesium infusion post-myocardial infarction (MI) has mixed results, with recent studies lacking significant mortality benefits compared to earlier trials. The effectiveness of magnesium may depend on the patient population, as sicker patients might require different interventions. However, magnesium has shown promise in managing rapid atrial fibrillation (AFib), aiding in both rate and rhythm control, and providing faster responses to treatment. Additionally, magnesium supports the repletion of other electrolytes, such as potassium, underscoring its multifaceted role in patient care.
