Acute myocardial infarction; hypomagnesemia in patients

ABSTRACT

This descriptive case series study evaluates the frequency of hypomagnesemia in patients with acute myocardial infarction. This multidisciplinary conducted at Liaquat University Hospital Hyderabad and a private hospital Hyderabad from May 2010 to October 2010. All patients diagnosed as acute myocardial infarction were further evaluated for type of myocardial infarction and serum magnesium level. Out of 100 diabetic patients, 77 were males and 23 patients were females. The mean age and standard deviation of patients of male and female was 54.78 +/- 8.82 [SD] and 53.64 +/- 10.82 [SD], respectively. The mean +/- SD for serum magnesium in overall subjects was 1.24 +/- 0.48. Regarding the type of AMI inferior wall in 22 [29%], lateral wall in 17 [22%], anteroseptal in 12 [16%], anterolateral -V1 in 07[09%], right ventricular in 10 [13%] and posterior wall in 07 [09%]. The mean duration of acute MI in male and female population was 8.71 +/- 6.73 hours and 17.70 +/- 14.57 hours [p<0.01] where as the mean duration of acute MI in hypomagnesemic and normomagnesemic patient was 5.16 +/- 2.49 hours and 26.60 +/- 8.27 [p = 0.02] respectively. The mean serum magnesium level in male as well as female population was 1.32 +/- 0.21 mg/dl and 1.46 +/- 0.53 mg/dl p = 0.05, respectively. Regarding the hypomagnesemia in male and female population was 34[75.6%] and 16[53.3%] p=0.04, respectively. The hypomagnesemia was more predominant in inferior 18[36.0%] and lateral 16 [32.0%] wall MI. The hypomagnesemia was observed in patients with acute myocardial infarction with statistical significance:
