Figure 2. Longitudinal and Circumferential Strain Lower in HFpEF Patients
HFpEF, heart failure with preserved ejection fraction; HHD, hypertensive heart disease; LVEF, left ventricular ejection fraction.
*P < .0001 compared with controls and between HHD and HFpEF overall for longitudinal strain and circumferential strain. **LVEF-adjusted P < .001 compared with controls. ***P = .0002 compared with controls.
