Abstract:
Objective:Three-dimensional speckle tracking echocardiography (3D-STE) was used to evaluate the left ventricular function in patients with triple vessel coronary artery disease without myocardial infarction.Methods:60 patients with three vessel disease of coronary heart disease without myocardial infarction treated in the Second Affiliated Hospital of Dalian Medical University from June 2018 to December 2020 were selected. They were divided into two groups according to the results of coronary angiography. There were 31 cases in group B, and the stenosis rate of all triple vessel coronary artery was 50%-<75%; 29 cases in group C, the stenosis rate of all triple vessel coronary artery was ≥75%; Thirty healthy subjects were recruited as the group A. We measured left ventricular (LV) end-diastolic and end-systolic volume (LVEDV, LVESV) and LV ejection fraction (LVEF) using real-time dynamic three-dimensional echocardiography. The LV strain parameters were acquired by 3D-STE, including global longitudinal strain (GLS), global area strain, global radial strain (GRS) and global circumferential strain (GCS). The correlation between 3D-STE parameters and N-terminal proBNP (NT-proBNP), left ventricular end-diastolic pressure (LVEDP) were analyzed by Pearson linear correlation analysis.Results:The LVEDV and LVESV in group A and B were significantly lower than those in group C (all P<0.05), and the absolute values of LVEF, GLS, GRS, GCS and GAS were higher than those in group C (all P<0.05). There were no significant difference in LVEDV, LVESV and LVEF between group B and group A (all P>0.05), while the absolute values of GLS, GCS and GAS in group B were significantly lower than those in group A (all P<0.05). The absolute values of GLS, GRS, GCS and GAS in group C were negatively correlated with NT-proBNP and LVEDP (all P<0.05). The absolute value of GLS in group B was negatively correlated with NT-proBNP ( P<0.05), and the absolute value of GLS, GRS, GCS and GAS was negatively correlated with LVEDP (all P<0.05). Conclusions:Our study shows that 3D-STE can evaluate the LV function in patients with triple vessel coronary artery disease without myocardial infarction through multiple strain parameters.
