Abstract

Background: To establish between hypomagnesemia and predicts excessive morbidity,
particularly ventricular tachyarrythmias in patients with acute myocardial infarction (AMI).
Method and Materials: A case control study was designed over one year period in 200 patients
with AMI (100 patients with ventricular tachyarrythmias and 100 patients without arrythmias)
whose admitted to a coronary care unite of khatam hospital of zahedan. For all of them serum
magnesium concentration was measured first and 12 hours later during 24h after AMI the patient’s
rhythm was continously recorded. The main study parameters were occurance of ventricular
tachyarythmias and lts relationship with hypomagnesemia.
Results: From 100 patients with AMI and ventricular tachyarrythmias mean ages were
57/2±12/9 (p=0/36) and first serum magnesium was 1/9 ± 0/46 (p=0/051) and second serum
magnesium was 2± 0/32 (p=0/003) and %55 of patients were male that from those patients due to
first serum magnesium 39 patients were hypomagnesemic, OR=2/4 and due to second serum
magnesium 36 patients were hypomagnesemic, OR= 10/7 and from 100 patients with AMI without
ventricular tachyarrythmias mean ages were 58/9 ± 12/3 (p=0/36) and first serum magnesium 2±
0/28 (p=0/051) and second serum magnesium 2/1± 0/18 (p=0/003) and %45 of patients were male
that from those patients due to first serum magnesium 21 patients were hypomagnesemic and due to
second serum mognesium only 5 patient were hypomagnesemic.
Conclusions: In this study we conclude that hypomagnesemia due to first serum magnesium can
increase 2/4 fold ventricular tachyarrythmias and due to second serum magnesium can Increase
10/7 fold.Thus hypomagnesemia can be a major risck factor for ventricular tachyarrythmias after
AMI and immediate diagnosis and treatment of hypomanesemid can reduce morbidity and mortality
after AMI. Thus we recommended that for any patients with AMI serum magnesium must be
measured at admission to CCU and initiate proper treatment for hypomagnesemia
