The Relationship Between Epicardial Fat Tissue and Cardiac Function in HFpEF Patients

Completed

• Conditions: Heart Failure With Preserved Ejection Fraction

• Registration Number: NCT05068934
• Lead Sponsor: Dongying Zhang

Brief Summary

Heart failure with preserved ejection fraction (HFpEF) refers to a group of symptoms and signs of heart failure, normal or near-normal left ventricular systolic function (EF\>50%), and ventricular muscle diastolic dysfunction and A clinical syndrome characterized by decreased compliance and increased stiffness. The pathogenesis of HFpEF is related to impaired lipid metabolism and inflammation. Epicardial adipose tissue (Epicardial Adipose tissue, EAT) is a kind of visceral adipose tissue. Related studies have shown that extracardiac Membrane fat is related to inflammation markers, cardiometabolic risk and cardiovascular disease.However, there is still no research investigating the the relationship between epicardial fat thickness and Cardiac Function in HFpEF patients.

Detailed Description

Heart failure with preserved ejection fraction (HFpEF) refers to a group of symptoms and signs of heart failure, normal or near-normal left ventricular systolic function (EF\>50%), and ventricular muscle diastolic dysfunction and A clinical syndrome characterized by decreased compliance and increased stiffness. The pathogenesis of HFpEF is related to impaired lipid metabolism and inflammation. Epicardial adipose tissue (Epicardial Adipose tissue, EAT) is a kind of visceral adipose tissue, which is composed of adipose tissue deposited between the myocardium and the visceral layer of the pericardium. It is closely adjacent to the coronary arteries and myocardium. Related studies have shown that extracardiac Membrane fat is related to inflammation markers, cardiometabolic risk and cardiovascular disease.However, there is still no research investigating the the relationship between epicardial fat thickness and Cardiac Function in HFpEF patients. This study intends to observe the relationship between epicardial fat thickness and left and right functions in patients with HFpEF, and evaluate whether epicardial fat thickness can be used as an indicator of left and right dysfunction.
