1, for patients with primary end points and event-free patients; 2, for patients with secondary end points and event-free patients. AUC, area under the curve; GCS, global circumferential strain; GLS, global longitudinal strain; RRS, regional radial strain of hypertrophic segments; RCS, regional circumferential strain of hypertrophic segments.
