Objective: To analyze the clinical value of the noninvasive left ventricular pressure-strain ring (LV-PSL) in the evaluation of left ventricular pressure-strain ring (LV-PSL) after treatment of patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: 90 patients with STEMI who were treated from October 2018 to September 2019 were selected as the observation group

and 90 healthy examinees from the physical examination center in the same period were selected as the comparison group

and the left heart function index

left ventricular reconstruction index and left ventricular overall longitudinal response rate (GLS) were detected and compared

the left ventricular myocardial work function index (GLS) was measured by LV-PSL examination

the left ventricular myocardial work function index was compared between the two groups

and the left ventricular remodeling index

left ventricular remodeling index

GLS

Left ventricular myocardial work indicators

Spearman correlation analysis of left ventricular myocardial work indicators and GLS

left ventricular ejection fraction (LVEF) correlation. Results: The left ventricular end-systolic volume (LVESV)

left ventricular end-diastolic volume (LVEDV)

and global invalid work (GWW) in the observation group were higher than those in the control group before and 3 days after operation. Work efficiency (GWE)

overall work index (GWI)

and overall effective work (GCW) were all lower than those in the control group

P＜0.05 (all differences were statistically significant). Before operation

the LVEF

GLS

GWE

GCW and GWI of observation group were higher than those before operation 3 days after operation

P<0.05 (the differences were all statistically significant). The preoperative and postoperative 3dLVEDV

LVESV

and GWW of the multivessel coronary stenosis group were higher than those of the single coronary stenosis group

and the preoperative and postoperative 3dLVEF

GLS

GWE

GCW

and GWI of the multivessel coronary stenosis group were lower than those of the single coronary stenosis group. Coronary artery stenosis group

P<0.05 (all differences were statistically significant). GWW was negatively correlated with GLS and LVEF

and GWE

GCW and GWI were positively correlated with GLS and LVEF

P<0.05 (all differences were statistically significant). Conclusion: Lv-PSL parameters in STEMI patients have a certain correlation with GLS and LVEF

and LV-PSL examination can accurately assess the left heart function and left ventricular remodeling of patients through LV-PSL examination

which has certain clinical value.
