説明
<p>Background:In patients with myocardial infarction (MI), microvascular obstruction (MVO) determined by cardiac magnetic resonance imaging (CMR) is associated with left ventricular (LV) remodeling and worse prognosis.</p><p>Methods and Results:In 71 patients with ST-segment elevation MI (STEMI) treated by primary percutaneous coronary intervention (PCI), speckle tracking echocardiography (STE) and CMR were performed early after PCI. All patients underwent CMR at 6 months after hospital discharge to assess the occurrence of LV remodeling. The values of 3-dimensional (3D)-circumferential strain (CS), area change ratio (ACR), and 2-dimensional (2D)-CS were significantly different for the transmural extent of infarct, whereas the values of 3D- and 2D- longitudinal strain (LS) were not significantly different. In transmural infarct segments, the values of 3D-CS and ACR were significantly lower in segments with MVO than in those without MVO. At 6-month follow-up, LV remodeling was observed in 22 patients. In multivariable logistic regression models, global 3D-CS and ACR were significant determinants of LV remodeling rather than the number of MVO segments.</p><p>Conclusions:Regional 3D-CS and ACR reflected the transmural extent of infarct and were significantly associated with the presence of MVO. In addition, global 3D-CS and ACR were preferable to the extent of MVO in the prediction of LV remodeling.</p>
