Traditional echocardiographic parameters for the assessment of suspected cardiac amyloidosis (CA) are of limited diagnostic accuracy. We sought to explore differences and the discriminative value of phasic left atrial strain (LAS) reductions and of regional longitudinal left ventricular (LV) strain alterations (relative apical sparing; RELAPS) in CA and other causes of LV wall thickening (LVH).

阶段性左心房应变分析鉴别厚厚心脏病变患者的心脏淀粉样变性

用于评估疑似心脏淀粉样变性 (CA) 的传统超声心动图参数的诊断准确性有限。我们试图探索在 CA 和 LV 壁增厚 (LVH) 的其他原因中，相位性左心房应变 (LAS) 降低和区域纵向左心室 (LV) 应变改变（相对心尖保留；RELAPS）的差异和鉴别价值。
