Kaplan-Meier survival curve of LV Score. Patients were divided into four groups with LV Score of 0, 1, 2, and 3, respectively, with 1 for patchy LV LGE, 2 for extensive LV LGE, and 1 for LV GLS ≥−11.85% (median value). Patients categorized by LV Score differed significantly in survival probability (100.0%, 75.0%, 73.7%, and 34.9% at the 21th month respectively, log-rank P<0.001). LV, left ventricular; GLS, global longitudinal strain.
