Kaplan-Meier survival curve demonstrates the discriminative prognostic value of AAPSE in cardiac biopsy proven AL amyloidosis. Cut-off (AAPSE ≤7.6 mm) was calculated by ROC analyses (AUC =0.80; CI: 0.68 to 0.89; p < 0.0001) and Youden’s-J statistic to predict all-cause death or heart transplantation within 6 months from index examination (n = 68)
