RÉSUMÉ

Objective:To explore the risk factors of left ventricular thrombosis (LVT) after acute myocardial infarction.Methods:A retrospective analysis was conducted on the clinical data of 300 patients with acute myocardial infarction admitted to the Xuhui District Central Hospital in Shanghai from January 2019 to January 2022. Based on the results of echocardiography, the patients were divided into LVT group (27 cases) and non LVT group (273 cases). Single factor analysis and multivariate logistic regression analysis were used to screen for the influencing factors of LVT formation after acute myocardial infarction. The value of predicting LVT formation was analyzed through receiver operating characteristic (ROC) curve analysis of each indicator.Results:There was no significant difference between the two groups in gender, age, body mass index (BMI), smoking history, drinking history, hypertension, diabetes, duration of chest pain<12 h, white blood cell count (WBC), platelet count (PLT), myocardial creatine kinase isoenzyme (CK-MB), creatinine, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) (all P>0.05), The differences in neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), C-reactive protein (CRP), brain natriuretic peptide (BNP) levels, left ventricular ejection fraction (LVEF), and left ventricular end diastolic diameter (LVDD) between the two groups of patients were statistically significant (all P<0.05); The area under the curve predicted by NLR, PLR, CRP, BNP, LVEF, and LVDD for LVT formation after acute myocardial infarction were 0.707, 0.771, 0.859, 0.754, 0.875, and 0.796 (all P<0.05), respectively. The predicted critical values for LVT formation were 3.571, 121.761, 45.215 mg/L, 415.196 pg/ml, 51.271%, and 43.364 mm, respectively; The results of multivariate analysis showed that PLR≥121.761, CRP≥45.215 mg/L, BNP≥415.196 pg/ml, LVEF≤51.271%, and LVDD≥43.364 mm were independent risk factors for LVT formation after acute myocardial infarction (all P<0.05). Conclusions:PLR, CRP, BNP, LVEF, and LVDD are independent risk factors for LVT formation after acute myocardial infarction.
