The area under the ROC curve was 94.7%, as verified by bootstrapping.<h4>Conclusion</h4>MCV, D-dimer level, CRP level, LVEF, A-wave velocity, pericardial effusion, and anterior wall infarction were independently related to the occurrence of LVT in STEMI at the acute stage. The gene discussed is CRP; the disease is pericardial effusion.
