[Intravenous magnesium in acute myocardial infarct].

Unlabelled: The effects of magnesium (Mg) on the incidence of arrhythmias and on mortality were evaluated in 61 patients with documented acute myocardial infarction (AMI), in a randomized, double blind placebo controlled study. During the first 24 hours 31 patients received infusion of 1000 ml isotonic saline with 17 g MgSO4 and 30 ones received only equal volumes of saline as placebo. The baseline characteristics of the population including serum Mg and potassium were similar in the two groups.
