Quantitative MCE at rest (A-C) and during vasodilator stress (E–G) for microvascular blood flow (MBF), microvascular blood volume (MBV) and microvascular flux rate according to presence or absence of fibrosis > 2% by late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging (CMR). (D and H) Relation between percent fibrosis by LGE and MBF at rest or stress. (I-K) Quantitative MCE during vasodilator stress according to the presence or absence of a history of anginal chest pain (CP). (E–G) Relation between left ventricular outflow tract (LVOT) gradient at rest and MBF at rest or during vasodilator stress
