The Diagnostic and Prognostic Value of Cardiac Magnetic Resonance Strain Analysis in Heart Failure with Preserved Ejection Fraction

Figure 1

(a) ROC curve of LA individual strains; (b) ROC curve of RV individual strains; (c) ROC curve of LV individual strains; (d) ROC curve of the combined analysis of LV strains. Abbreviation: HFpEF, heart failure with preserved ejection fraction; AUC, area under curve; GRS, global radial strain; GCS, global circumferential strain; GLS, global longitudinal strain; LA, left atrium; LV, left ventricle; RV, right ventricle.
