About

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 blood pressure and arterial stiffness in HFpEF patients with different levels of obesity.

Full description

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 blood pressure and arterial stiffness in HFpEF patients with different levels of obesity.
