Relationship Between Adipose Tissue Distribution and Arterial Stiffness in HFpEF

Chongqing Medical University50 enrolled

Overview

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. Studies have found that hypertension and obesity are respectively associated with increased arterial stiffness. However, there is still no research investigating the the relationship between lipids distribution and arterial stiffness in HFpEF patients.

Before the 21st century, Heart failure with preserved ejection fraction (HFpEF) was considered as a disease with simple diastolic dysfunction, but after the 21st century, 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. Other studies have found that hypertension and obesity are respectively associated with increased arterial stiffness. However, there is still no research investigating the the relationship between lipids distribution and arterial stiffness in HFpEF patients.
