Objective: The left atrial volume (LAV) is an important prognostic factor in cardiovascular disease. However, in acute myocardial infarction (AMI), the factors affecting the changes in LAV index (ΔLAVi) has not been established yet.
Methods: In one hundred eight subjects (M:F = 74:34; mean age, 62 ± 13 years) with AMI transthoracic echocardiogram was followed up at baseline and 20 months after AMI. The clinical and echocardiographic parameters related to ΔLAVi were analysed.
Results: The mean ΔLAVi was 7.94 ± 9.10 mL/m2. ΔLAVi is related to the history of hypertension (r=0.197, p=0.040), fasting blood glucose (FBG) at baseline (r=0.310, p=0.001), E-wave velocity at baseline (r=-0.209, p=0.030), the change of E/E’ (r=0.246, p=0.011) and the change of LVEF (ΔEF) (r=-0.214, p=0.026). Based on multivariate analysis, FBG, E wave velocity at baseline and ΔEF were closely related to ΔLAVi (Table).
Conclusions: LA remodeling after AMI is related to clinical and hemodynamic parameters such as FBG, diastolic function and systolic function.
