ECV (%)	25.5 ± 3.1	25.0 ± 2.7	24.6 ± 3.2	26.3 ± 3.1	<0.001	1.0	<0.001
Stress MBF (mL/g/min)	1.72 ± 0.59	1.96 ± 0.61	1.89 ± 0.62	1.51 ± 0.50	<0.001	1.0	<0.001
Rest MBF(mL/g/min)	0.72 ± 0.22	0.78 ± 0.27	0.71 ± 0.19	0.70 ± 0.22	0.070	0.170	1.0

Values of native T1, ECV, and stress MBF were not significantly different between HFpEF and HFmrEF. T1 and ECV were significantly higher in HFrEF, and stress MBF significantly lower, when compared with HFmrEF.
