Time-Dependent Regional Myocardial Strains in Patients with Heart Failure with a Preserved Ejection Fraction

Figure 5

(a)–(f) Average circumferential strain over one cardiac cycle for control (black) versus HFpEF patients (red). Strains at each of the regions of the heart both endocardium (endo) and epicardium (epi) are displayed: base endo, epi (a, b), mid endo, epi (c, d), and apex endo, epi (e, f).
