The assessment of left ventricular ejection fraction (LVEF)
Brief summary
compare measurements of left ventricular volumes and LVEF obtained by 2DE, 3DE, and CMR after a ST elevation myocardial infarction (STEMI) complicated by systolic left ventricular dysfunction
Detailed description
The assessment of left ventricular ejection fraction (LVEF) is a critical step after a myocardial infarction because it determines the prognosis and the therapeutic management (indication of implantable cardioverter-defibrillators). Three-dimensional echocardiography (3DE) and cardiac magnetic resonance (CMR) are accurate and reproducible techniques to quantify left ventricular volumes and LVEF. However, all the large randomized trials which evaluated the role of the implantable cardioverter-defibrillators (ICD) on survival in primary prevention were based on LVEF values obtained by older techniques like bi-dimensional echocardiography (2DE), angiography or radionuclide scanning. From now, no study has compared the measurements of left ventricular volumes and LVEF obtained by further current techniques after an acute myocardial infarction (AMI) particularly after 1 month when ICD could be indicated.
