Evaluation of serum magnesium levels in patients with acute myocardial infarction

Abstract

Aim: To evaluate the serum magnesium levels in patients with acute myocardial infarction. Material and method: The present prospective observational study was conducted in the department of Medicine among 50 patients with acute myocardial infarction. Patients who presented to the hospital within 24 hours of onset of symptoms and diagnosed with acute myocardial infarction were included in the study. Blood samples collection were taken within 24 hours of onset of symptoms. All patients were evaluated for their ECG and cardiac enzymes and serum magnesium level by taking 5 cc venous blood sample in a disposable syringe and sent to biochemistry laboratory for analysis in fluoride bulb and plain bulb respectively. Results: Smoking was reported in 82% of the subjects whereas hypertension and diabetes mellitus in 64% and 46% of the subjects respectively. Sixteen percent, 24% and 60% of the subject’s time of presentation was 3-6 hours, 6-12 hours and 12-18 hours respectively. On day 5, only six percent (3) of the subjects with arrhythmia were having serum magnesium level (mg/dL) <1.6 while 14% of the subjects with arrhythmia reported 1.7-2.4 serum magnesium level (mg/dL). There was an increase in serum magnesium from Day-1 to Day-5 with statistically significant difference.
