Abstract

Objectives This study determined the impact of excess epicardial adipose tissue (EAT) in patients with the obese phenotype of heart failure with preserved ejection fraction (HFpEF).Background Patients with HFpEF and an elevated body mass index differ from nonobese patients, but beyond generalized obesity, fat distribution may be more important. Increases in EAT are associated with excess visceral adiposity, inflammation, and cardiac fibrosis, and EAT has been speculated to play an important role in the pathophysiology of HFpEF, but no study has directly evaluated this question.Methods Patients with HFpEF and obesity (n = 169) underwent invasive hemodynamic exercise testing with expired gas analysis and echocardiography. Increased EAT was defined by echocardiography (EAT thickness ≥9 mm).Results Compared with obese patients without increased EAT (HFpEF EAT-, n = 92), obese patients with HFpEF with increased EAT (HFpEF EAT+; n = 77) displayed a higher left ventricular eccentricity index, indicating increased pericardial restraint, but similar resting biventricular structure and function. In contrast, hemodynamics were more abnormal in patients with HFpEF EAT+, with higher right atrial, pulmonary artery, and pulmonary capillary wedge pressures at rest and during exercise compared with those of patients with HFpEF EAT-. Peak oxygen consumption (VO 2) was reduced in both groups but was 20% lower in patients with HFpEF EAT+ (p < 0.01).Conclusions Among patients with the obese phenotype of HFpEF, the presence of increased EAT is associated with more profound hemodynamic derangements at rest and exercise, including greater elevation in cardiac filling pressures, more severe pulmonary hypertension, and greater pericardial restraint, culminating in poorer exercise capacity. Further study is needed to understand the biology and treatment of excessive EAT in patients with HFpEF.

  • EAT mass may drive an abnormal ventricular distensibility determining a constrictive pattern responsible of pressure equalization across ventricles in different physiologic states, particularly during exercise and in patients with obesity and with or without diabetes.

    “Occupying a fixed pericardial space, the EAT mass may drive an abnormal ventricular distensibility determining a constrictive pattern responsible of pressure equalization across ventricles in different physiologic states, particularly during exercise and in patients with obesity and with or without diabetes [85,86].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
