Investigating the impact of heart fat on heart function in patients with heart failure

The Role of Epicardial Adiposity in Heart Failure With Preserved Ejection Fraction

Observational University of Leicester · NCT06768437

This study is trying to see how fat around the heart affects heart function in people with heart failure, including those who are obese and those who are not.

What this trial studies

This observational study aims to recruit 130 patients diagnosed with heart failure with preserved ejection fraction (HFpEF), both obese and non-obese, to explore the relationship between epicardial adipose tissue (fat around the heart) and heart function. Participants will undergo CT and MRI scans, along with blood tests, to assess how excess fat may contribute to cardiac dysfunction in HFpEF. The study seeks to provide insights into the mechanisms by which adiposity affects heart health, potentially leading to new treatment strategies for this condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older diagnosed with HFpEF, regardless of their obesity status.

Not a fit: Patients with severe primary valvular heart disease or those with a left ventricular ejection fraction below 45% may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new treatments aimed at reducing fat levels around the heart, improving outcomes for patients with HFpEF.

How similar studies have performed: While there have been studies on obesity and heart failure, this specific approach focusing on epicardial adipose tissue in a diverse cohort is relatively novel.

Eligibility criteria
