Incidence, time course, and predictors of early malignant ventricular arrhythmias after non-ST- segment elevation myocardial infarction in patients with early invasive treatment

This issue is very important because it is still hard to predict these life-treatening arrhythmias in individual patients with myocardial infarction, especially if good reperfusion is acheived. It still remains uncertain, when considering the pathophysiology of these arrhythmias in patients with myocardial infarction, whether these are really caused by reperfusion (coronary intervention, medicamentous, spontaneous) or ischaemia?5 Further investigations should be directed towards discovering predictors of malignant ventricular arrhythmias after reperfusion in both NSTEMI and STEMI, as well as redefining VT/VF as reperfusion arrhythmias according to pathophysiological and clinical criteria. Finally, we agree that the problem of VT/VF in patients with myocardial infarction and mechanically achieved good reperfusion becomes of lesser significance after the first 24 h, which is important from an economic point of view.
