[Early mortality among patients with supraventircular tachyarrhythmia after acute myocardail infarction]

ABSTRACT

In this study the frequency of early term mortality [1 months] was evaluated among patients with early supraventricular tachyarrhythmia [<72 hours] during the first acute myocardial infarction [AMI]. In this prospective descriptive study, we studied 315 patients with the first S-T elevation AMI. Various factors including age, gender, risk factors and types of supraventricular tachyarrhythmias [within first 72 hours of CCU admission] were assessed based on medical records. Early cardiovascular mortality [30 days sudden cardiac death or acute coronary syndrome complicated with death] was probed through out-patient clinic. Among 300 patients, 208 individuals [69.3%] had one tachyarrhythmia with 8.1% mortality, 78 patients [26%] had two tachyarrhythmia with 12.8% mortality and the rest 11[3.7%] had three tachyarrhythmia with 45% mortality. Mortality among patients with and without atrial tachycardia [AT] was 36% and 9.4%, respectively [p<0.05], but in patients with and without atrial fibrillation [AF] was 20% and 9%, respectively [p>0.05]. Mortality among patients with and without atrial premature contraction [APCs] was 8% and 14%, respectively, [p>0.05] while among patients with and without sinus tachycardia [ST] was 15% and 5%, respectively. [p<0.05]. Early mortality [within 30 days] was more frequent among patients with S-T elevation myocardial infarction complicated with sinus tachycardia, atrial tachycardia and multiple simultaneously supraventricular tachyarrhythmia
