Résumé
Objective To explore the prognostic value of ventricular wall motion score (WMS) and left ventricular ejection fraction (LVEF) in patients with acute myocardial infarction (AMI) combined with heart failure (HF) in the recent 12 months Methods We selected hospitalized AMI patients in our department from Jan. 2014 to Nov. 2014. Cardiac ultrasound was performed to detect WMS and LVEF within 48 hours and during the 6?month follow?up period and the occurrence of HF was recorded. Results Totally 127 AMI patients were recruited, including 20 cases combined with HF. The WMS was higher in HF group than those in non?HF group (23.55 ± 3.73 vs 20.11 ± 3.13, P<0.01), while the LVEF in HF group was lower than those in non?HF group (48.77 ± 8.08 vs 56.99 ± 5.17, P<0.01). Multiple logistic regression analysis revealed that WMS and LVEF were both independent predictors of HF in the recent 12 months (P < 0.05). The prediction effect of WMS ROC curve area was 0.81 (P < 0.01) , and LVEF 0.76 (P < 0.05). WMS and LVEF combined assessment area under ROC curve was 0.82 (P < 0.01). Conclusion WMS and LVEF are independent predictors of HF in patients with AMI in the recent 12 months and the combined application of WMS and LVEF can significantly improve the prediction effect.
