Treatment of arrhythmias after myocardial infarction - indications for implantable cardioverter-defibrillator
Journal Title: Postępy Nauk Medycznych - Year 2010, Vol 23, Issue 8
Abstract
The most common mechanism of sudden cardiac death (SCD) is ventricular fibrillation (VF). Patients with myocardial infarction are particularly at risk of sudden cardiac death. Indications for implantable cardioverter-defibrillator (ICD) can be classified as primary and secondary prevention.Secondary prevention applies to patients who have experienced hemodynamically unstable, sustained ventricular tachycardia (nsVT) or ventricular fibrillation. Ventricular arrhytmias occurring within 48 hours of myocardial infarction associated with reversible changes in ischemic myocardial tissue are not an indication for implantable cardioverter-defibrillator. Patients with left ventricular dysfunction, low ejection fraction are at risk of SCD. They are good candidates for implantation ICD in primary prevention, 40 days after MI.70% of ICD after myocardial infarction were implanted in Bielański Hospital in primary prevention in 2009. During the annual follow-up (± 3 months) in 17% of that group of patients sVT or VF were occurred. Effectiveness of the ICD was 100%.Key words: cardioverter-defibrillator, secondary prevention, primary prevention, myocardial infarction, ventricular fibrillation
