Heart failure with preserved ejection fraction (HFpEF) was considered as a heterogeneous disease with multi-organ and multi-system design, which is related to various complications, such as hypertension, obesity and arteriosclerosis. Ambulatory arterial stiffness index (AASI) is associated with arteriosclerosis and hypertension. There is no report on whether AASI is associated with left ventricular diastolic dysfunction in patients with HFpEF.

Heart failure with preserved ejection fraction (HFpEF) is related to various complications, such as hypertension, obesity and arteriosclerosis. Ambulatory arterial stiffness index (AASI) is associated with arteriosclerosis and hypertension. AASI is especially associated with left ventricular diastolic dysfunction in patients with hypertension. Patients with HFpEF have obvious left ventricular diastolic insufficiency. However, there is still no research investigating the the relationship between AASI and left ventricular diastolic dysfunction in patients with HFpEF.
