Fig 4. Comparative receiver-operating curves of guideline and new echocardiographic parameters for HFpEF diagnosis.

Fig 4

The new echocardiographic parameters (Panel B) showed higher AUC compared to all current guideline parameters (Panel A). A combined index of 3 from 5 parameters with the highest AUC (SR_CT, sPAP, GS, DI, LAVi min) identified HFpEF better than the actual guideline index and all parameters alone, including the new ones. LAVi, left atrium volume indexed; E/E’, ratio between early diastolic mitral inflow to mitral annular early diastolic tissue velocities; LVMi, left ventricle mass indexed; sPAP, systolic pulmonary arterial pressure; GS, global strain; SR_CT, LA contractile strain rate; DI, distensibility index; S_R, LA reservoir strain.
