Objective. The most important step in the treatment of ST elevation myocardial infarction is to sustain myocardial blood supply as soon as possible. The two main treatment methods used today to provide myocardial reperfusion are thrombolytic therapy and percutaneous coronary intervention. In our study, reperfusion arrhythmias were investigated as if they are indicators of coronary artery patency or ongoing ischemia after revascularization. Methods. 151 patients with a diagnosis of acute ST elevation myocardial infarction were investigated. 54 patients underwent primary percutaneous coronary intervention and 97 patients were treated with thrombolytic therapy. The frequency of reperfusion arrythmias following revascularization procedures in the first 48 hours after admission was examined. The relation between reperfusion arrhythmias, ST segment regression, coronary artery patency, and infarct related artery documented by angiography were analyzed. Results. There was no statistically significant difference between the two groups in the frequency of reperfusion arrhythmias (P = 0.355). Although angiographic vessel patency was higher in patients undergoing percutaneous coronary intervention, there was no significant difference between the patency rates of each group with and without reperfusion arrythmias. Conclusion. Our study suggests that recorded arrhythmias following different revascularization procedures in acute ST elevation myocardial infarction may not always indicate vessel patency and reperfusion. Ongoing vascular occlusion and ischemia may lead to various arrhythmias which may not be distinguished from reperfusion arrhythmias.

Aim: The objective of this study was to compare the periprocedural and clinical outcomes after carotid artery stenting (CAS) with proximal protection devices versus with distal protection devices. Material and methods: Patients with internal carotid artery (ICA) stenosis undergoing CAS with cerebral embolic protection were randomly assigned to proximal balloon occlusion or distal filter protection. Adverse events were defined as death, major stroke, minor stroke, transient ischemic attack (TIA) and myocardial infarction (MI). Periprocedural and 30-day adverse events and ICA vasospasm rates were compared between the two embolic protection groups. Results: Eighty-eight consecutive patients were randomized: 48 patients with proximal protection (mean age 68.8 +/- 13.6, 66\% male) and 40 patients with a distal protection device (mean age 65.4 +/- 12.3
