Reperfusion arrhytmias in patients with acute stemi treated with primary PCI

After therapy induced or spontaneous opening of a coronary artery in acute myocardial infarction, complex humoral and cellular reactions ensue, causing among other effects reperfusion arrhythmias. Most reperfusion arrhythmias are generally innocuous, but when reperfusion arrhythmias cause hemodynamic instability or subjective discomfort, therapy identical to that for identical arrhythmias of different origin should be introduced. Authors prospectively investigated 82 patients who suffered acute STEMI and were treated with primary PCI. Frequency and treatment of reperfusion arrhythmias that occurred 24 hours after primary PCI, as well as, MACE (angina pectoris, re-IM, re-PCI or CABG, CVI, death) in one year period of follow-up have been observed. Investigated reperfusion arrhythmias were sinus bradycardia, accelerated idioventricular rhythm, frequent premature ventricular complexes (PVC), non-sustained and sustained ventricular tachycardia(NS-VT, S-VT), high-degree atrioventricular and ventricular fibrillation (VF). Results confirm predictive value of NS-VT, PVC, S-VT and VF in acute STEMI patients treated with primary PCI. According to these results, NS-VT is the best indicator of successful reperfusion among reperfusion arrhythmias, while S-VT and VF represent direct complications of ischemic myocardial lesion and can not be classified as reperfusion arrhythmias.
