The outcomes measured at 30 days included death from cardiovascular causes, ventricular dysrhythmias, nonfatal MI, recurrent chest pain, and recurrent cocaine use.
Of the 256 who were contacted directly, none had sustained ventricular dysrhythmias. Only 1.6% (95% confidence interval [CI], 0.1%-3.1%) of subjects had subsequent nonfatal MI--all of whom had at least 2 cardiac risk factors and subsequent cocaine use.
However, treatment is obviously necessary in patients with symptomatic and/or life-threatening atrial and ventricular dysrhythmias. In addition, dysrhythmias are important risk factors for cardio-embolic stroke.
It has beep shown to be effective in both atrial and ventricular dysrhythmias and clear indications for its use have been established.
The most frequent indications were |resistant' atrial fibrillation (24%), malignant ventricular dysrhythmias (22%), and paroxysmal atrial fibrillation (20%) in 49 patients aged between 70 and 92 years (mean: 80 years).
It has generally been accepted that hypomagnesemia results in increased supraventricular and ventricular dysrhythmias and incidence of Torsade's de Pointes [19].
Eight patients developed serious ventricular dysrhythmias (sustained ventricular tachycardia and ventricular fibrillation) after admission; all responded to routine measures.
Clinical factors such as acute myocardial infarction and cardiomyopathy that contribute to ventricular remodeling and dilatation increase the frequency of ventricular dysrhythmias (Effat, 1995).
