APLN and anterolateral myocardial infarction: The formula for calculating the total point of the nomogram is as follows: 1.0304 ∗ (apelin change rate) + 9.5522 ∗(apelin) + 0.9600 ∗ (age) + 1.9201 ∗ I (pathological Q wave) +2.4603 ∗ I (myocardial infarction history) + 2.0949 ∗ I (anterior wall myocardial infarction) + 0.5206 ∗ I (Killip's classification > I) + 1.0043 ∗ (uric acid) + 0.6826 ∗ (total cholesterol) + 0.9756 ∗ (cTnI) + 0.9332 ∗ (left atrial diameter).
