Significance of serum magnesium and electrolyte levels in acute myocardial infarction in first six hours.
Pak J Cardiol Jan ;17(1):25-9.

Introduction: In this study, serum magnesium and Na+ and K+ levels were studied in 88 patients of acute myocardial infarction (AMI) having their first episode and 37 healthy controlled subjects. All the AMI patients met the criteria of JSCC (2000). They were carefully selected by strict inclusion and exclusion criteria. Patients of AMI were divided into three groups on the basis of their age. Methods:- All the patients were selected from the Emergency Department of Punjab Institute of Cardiology, Lahore. Prior to the starting of specific therapy streptokinase, a detailed history and general physical examination was performed and after meeting the AMI criteria for diagnosis consent proforma was filled, blood samples were collected in each case at the time of admission in the Emergency Ward. Results:- At the time of admission, serum magnesium levels were highly significantly lower (P < 0.001) as compared with the control group. Serum potassium levels were non significant (P > 0.05) in patients of AMI under the age of 60 years. While above the age of 60 years the serum potassium levels were significantly lower in the patients of AMI (P<0.05). Conclusion: - It was concluded from this study that there was statistically significant hypomagnesemia (P<0.001) in the patients of AMI at the time of admission. It was also noted that there was significant hypokalemia in AMI patients (P<0.05) over the age of 60 years.
