The aim of this study was to evaluate in patients with microvascular angina and heart failure with preserved ejection fraction, the speckle‐tracking echocardiography, and longitudinal myocardial strain to evaluate the possible presence of alterations in heart failure with preserved ejection fraction patients compared with a control population. We also investigated the correlation between the longitudinal strain analysis and the TIMI frame count after coronary angiography.

保留射血分数的心力衰竭患者的纵向应变分析与冠状动脉微血管功能障碍之间的相关性。

这项研究的目的是评估射血分数保留的微血管性心绞痛和心力衰竭患者，散斑跟踪超声心动图和纵向心肌应变，以评估射血分数保留的患者与对照组相比是否存在心力衰竭的改变人口。我们还研究了冠状动脉造影后纵向应变分析与TIMI框架计数之间的相关性。
