心脏磁共振在评估急性心肌梗死后心室重构中作用的研究进展

Cardiac magnetic resonance in the evaluation of ventricular remodeling after acute myocardial infarction

心肌梗死后心肌细胞坏死和梗死区扩张引起室壁应力增加,导致心室不良重构,是心力衰竭发生的主要原因。早期评估心肌梗死患者心室重构对预防心力衰竭的发生有重要价值。心脏磁共振具有空间分辨率高、视野大等优势,可多方位、多角度、多参数成像,准确显示心脏形态及功能,已成为评估心肌梗死面积大小和心室重构的影像学方法。本文就心脏磁共振在评估急性心肌梗死后心室重构中作用的研究进展作一综述。

The increase of ventricular wall stress induced by the loss of cardiomyocytes and infarcted area expansion after myocardial infarction results in poor ventricular remodeling, which is the main cause of heart failure. Early detection of ventricular remodeling in patients with myocardial infarction plays an important role in preventing the occurrence of heart failure. Cardiac magnetic resonance has the advantages of high spatial resolution and large field of vision, and can accurately show the shape and function of the heart by multi-directional, multi-angle and multi-parameter imaging, therefore it has become the main imaging method to evaluate the size of myocardial infarction and ventricular remodeling. This paper reviews the research progress of the application of cardiac magnetic resonance in the evaluation of ventricular remodeling after acute myocardial infarction.
