ARTICLE HIGHLIGHTS
Research background

Obesity has become a serious public health issue, significantly elevating the risk of various complications. It is a well-established contributor to Heart failure with preserved ejection fraction (HFpEF). Evaluating HFpEF in obesity is crucial. Epicardial adipose tissue (EAT) has emerged as a valuable tool for validating prognostic biomarkers and guiding treatment targets. Hence, assessing EAT is of paramount importance. Cardiovascular magnetic resonance (CMR) imaging is acknowledged as the gold standard for analyzing cardiac function and morphology. We hope to use CMR to assess EAT as a bioimaging marker to evaluate HFpEF in obese patients.

Research motivation

The aim of this study was to clarify the utility of using CMR-measured EAT as a diagnostic biomarker for assessing HFpEF in obese patients.

Research objectives

This study aims to employ CMR to examine EAT in the obese population with and without HFpEF, considering the association with co-morbidities, biomarkers, contractility parameters, and myocardial function assessed by CMR.

Research methods

The study was designed as a case-control, prospective clinical study. Obese patients were divided into two groups for a case-control study based on whether or not they had heart failure with HFpEF. The two groups were defined as HFpEF+ and HFpEF-. LV geometry, global systolic function, EAT volumes and EAT mass of all subjects were obtained using cine magnetic resonance sequences. The novelty of this study is to investigate EAT metrics (including volume or mass) in obese patients using CMR to determine whether or not EAT metrics are associated with HFpEF and whether EAT metrics appear to be a biomarker for predicting HFpEF in the obese population.

Research results

Forty-five patients of HFpEF- group and seventeen patients of HFpEF+ group were included. LV mass index (g/m2) of HFpEF+ group was higher than HFpEF- group (P < 0.05). In HFpEF+ group, EAT volumes, EAT volume index, EAT mass, EAT mass index and EAT/ left atrial (LA) left-right (LR) diameter ratio were higher compared to HFpEF- group. In multivariate analysis, higher EAT/LA LR diameter ratio was independently associated with higher odds ratio (OR = 4.597) of HFpEF.

Research conclusions

There was a strong correlation between increased EAT volumes and HFpEF in the obese. EAT/LA LR diameter ratio is highly associated with HFpEF in the obese.

Research perspectives

Given the significant findings, there may be some diagnostic utility in CMR for assessing the obese for HFpEF.
