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

Table 4

Average peak rotation in the base, mid, and apical regions of the heart for both the endocardium (endo) and epicardium (epi) for control patients versus HFpEF patients.

Myocardium layer,; myocardium level	Control peak; rotation (degrees)	HFpEF peak; rotation (degrees)	Absolute difference between; control and HFpEF (degrees)	value
Base, endo	1.16 ± 3.36	1.51 ± 6.07	0.35	<0.001
Base, epi	0.83 ± 2.58	1.39 ± 5.62	0.56	<0.001
Mid, endo	1.83 ± 5.06	1.66 ± 7.54	0.18	0.479
Mid, epi	1.31 ± 3.44	0.79 ± 5.12	0.52	0.167
Apex, endo	3.94 ± 9.16	2.05 ± 6.40	1.89	<0.001
Apex, epi	2.73 ± 6.50	2.25 ± 6.25	0.48	0.147
