Risk stratification for complex ventricular arrhythmia complicating ST-segment elevation myocardial infarction.

Objectives: The primary aim of the study was to evaluate risk factors for ventricular fibrillation/sustained ventricular tachycardia (VF/VT) and to develop the risk score for prediction of VF/VT in patients with ST-segment elevation myocardial infarction (STEMI) treated invasively. The secondary aim was to assess the effect of VF/VT on mortality depending on timing of arrhythmia.

Patients And Methods: We analyzed 4363 consecutive patients with STEMI treated invasively.

The risk of stroke in patients with acute myocardial infarction treated invasively.

Background: To assess the incidence, clinical significance, and independent risk factors of stroke in patients with acute myocardial infarction (AMI) treated invasively.

Materials And Methods: We analyzed 2520 consecutive patients with AMI admitted between 2003 and 2007. Data on long-term follow-up were screened to identify patients who had stroke.
