Background and Objective: Myocardial infarction and its complications, such as arrhythmia, may have magnesium as an underlying cause. Adding magnesium to your diet can help your heart's metabolism, which in turn reduces the risk of calcium buildup and cell death. Researching the association between arrhythmias and serum magnesium levels in patients suffering from acute myocardial infarction was the primary goal of the study.

Method: A total of 50 instances of acute myocardial infarction were randomly selected from patients hospitalised to Department of General Medicine, Sambhram Institute of Medical Sciences and Research, BEML Nagar, Kolar Gold Fields, Karnataka, India. This study was conducted between the periods of over a 12 month period, from April 2017 to March 2018.

Results: One of the leading causes of death and disability globally is coronary artery disease. Arrhythmias and other consequences of coronary artery disease are leading causes of mortality. Compared to patients with normal magnesium levels, those with low magnesium levels after an acute myocardial infarction were more likely to develop ventricular arrhythmias, according to this study. Potentially lowering the occurrence of arrhythmias, magnesium replacement treatment may be administered to individuals with acute myocardial infarction who exhibit low serum magnesium levels. Patients' magnesium levels differ significantly between those with and without arrhythmias.

Conclusion: Patients experiencing arrhythmias are more likely to have low magnesium levels following an acute myocardial infarction. Acute myocardial infarction patients with low magnesium levels may benefit from magnesium therapy.
