INTRODUCTION: More than half of heart failure patients have normal- appearing contraction as reflected by the percent of blood ejected with each heartbeat, the ejection fraction (EF). This syndrome, known as heart failure with preserved ejection fraction (HFpEF), confers substantial morbidity and mortality and has few effective treatments. It historically affected elderly individuals with hypertension and thickened hearts, but most HFpEF patients now have obesity, often severe, that is associated with worse clinical outcomes. Underlying cellular abnormalities in human HFpEF heart muscle and any potential impacts of coexisting severe obesity remain largely un- known. …
