AIM To investigate the value of ultrasound ventricle end-diastolic wall stress for predicting acute myocardial infarction (AMI) patients’ adverse cardiovascular outcomes.
METHODS A retrospective analysis was conducted in 160 AMI cases in Beijing Fengtai Integrated Traditional Chinese and Western Medicine Hospital from June 2017 to August 2019. All the patients were treated with PCI surgery. EDWS, ESWS, LVEF, Galectin-3, and peak troponin of all patients were tested after surgery. The patients were divided into group A (without adverse cardiovascular outcomes) and group B (with adverse cardiovascular outcomes) based on adverse cardiovascular outcomes. The ROC curve was used to value the sensitivity and specificity of EDWS, ESWS, LVEF, Galectin-3, and peak troponin for predicting adverse cardiovascular outcomes. The results were compared between the two groups.
RESULTS There were 37 patients who had adverse cardiovascular outcomes such as cardiac mortality, recurrent MI, and revascularization. LVEF of group B was lower than that of group A (P<0.05). EDWS, ESWS, Galectin-3, and peak troponin of group B were (16±3)MPa, (67±7)MPa, (18±6)ug/L and (94±11) μg/L, which were higher than those of group A (all P<0.01). EDWS, ESWS, LVEF, Galectin-3, and peak troponin all had high efficiency for predicting adverse cardiovascular outcomes. The AUC of EDWS was the biggest and the cut-off amount was 15.17. The sensitivity of EDWS was 94.31% and the specificity was 85.38%.
CONCLUSION EDWS has higher efficiency to predict the adverse cardiovascular outcomes for acute myocardial infarction patients, with high sensitivity and specificity. Its diagnostic value is worthy of clinical reference.
