Assessment of left ventricular myocardial function before and after percutaneous coronary intervention in patients with angina pectoris using two-dimensional longitudinal strain echocardiography
超声斑点追踪二维纵向应变评价心绞痛患者冠状动脉介入治疗术前后左心室心肌收缩功能

Objective To explore the characteristics of two-dimensional strain of left ventricular myocardial function before and after percutaneous coronary intervention(PCI) in the patients with angina pectoris (AP) by speckle tracking echocardiography. Methods A total of 32 patients with AP and 30 healthy volunteers were involved. High frame rate two-dimensional images were recorded from the apical four-chamber view,two-chamber view and long-axis view of the left ventricle,respectively. The peak systolic longitudina...
