Figure 4 Adjusted survival curves of patients with left atrial (LA) volume index 
32 ml/m2 and with LA volume index >32 ml/m2 were constructed using variables entered into the Cox model: age, gender, Killip class 2, primary reperfusion, diabetes, systemic hypertension, paroxysmal atrial fibrillation, previous myocardial infarction, left ventricular ejection fraction, moderate and severe mitral regurgitation, and restrictive left ventricular filling pattern. p = 0.02.
