本研究使用二维应变超声心动图评估冠状动脉狭窄≥70%对静息时局部舒张变形的影响。在行冠状动脉造影24h内,对患者前瞻性施行二维超声心动图成像。在3个主要血管分布区域测量以下指标:纵向收缩期(SRs)、舒张早期(SRe)和舒张晚期应变率,收缩期、
This study used two-dimensional strain echocardiography to assess the effect of ≥70% coronary stenosis on local diastolic deformation at rest. Within 24 hours of coronary angiography, patients were prospectively performed two-dimensional echocardiography. The following indices were measured in three major vascular regions: longitudinal systolic (SRs), early diastolic (SRe) and late diastolic strain rate, systolic,
