Prevalence of heart failure with preserved left ventricular ejection fraction amounts to 50% of all cases with heart failure. Diagnosis assessment requires evidence of left ventricular diastolic dysfunction. Currently, echocardiography is the method of choice for diastolic function testing in clinical practice. Various applications are in use and recommended criteria are followed for classifying the severity of dysfunction. Cardiovascular magnetic resonance (CMR) offers a variety of alternative applications for evaluation of diastolic function, some superior to echocardiography in accuracy and reproducibility, some being complementary. In this article, the role of the available CMR applications for diastolic function testing in clinical practice and research is reviewed and compared to echocardiography.
射血分数保留的心力衰竭在所有心力衰竭病例中占比达50%。诊断评估需要左心室舒张功能障碍的证据。目前,超声心动图是临床实践中舒张功能检测的首选方法。有多种应用方式且遵循推荐标准对功能障碍的严重程度进行分类。心血管磁共振(CMR)为舒张功能评估提供了多种替代应用,有些在准确性和可重复性方面优于超声心动图,有些则具有互补性。本文对临床实践和研究中现有的CMR舒张功能检测应用的作用进行了综述,并与超声心动图进行了比较。
