CARISMA : Cardiac Arrhythmias and Risk Stratification After MyoCardial Infarction

Incidence and Prediction of Life-threatening Cardiac Arrhythmias in Patients With Depressed Left Ventricular Function After Acute Myocardial Infarction

The purpose of this study is to assess the incidence of tachy- and bradyarrhythmic episodes in patients with acute myocardial infarction with depressed ventricular function and to determine the predictive value of several invasive and non-invasive risk markers for life-threatening arrhythmia

Inclusion Criteria:

• Acute myocardial infarction (< 21 days)
• Ejection fraction <= 40 % or wall motion index <= 1.3

Exclusion Criteria:

• Implantable loop recorder can't be implanted within 3 weeks after MI
• NYHA class IV
• Planned or previous ICD implantation
• Planned CABG
• Severe valvular disease
• Pregnancy
• Life expectancy < 1 year for non-cardiac cause
