Abstract:AimsHeart failure (HF) with supranormal ejection fraction (HFsnEF) represents a distinct clinical entity characterized by limited treatment options and an unfavourable prognosis. Revealing its phenotypic diversity is crucial for understanding disease mechanism and optimizing patient management. We aim to identify phenotypic subgroups in HFsnEF using unsupervised clustering analysis.MethodsConsecutive hospitalized patients with a diagnosis of HF and a left ventricular ejection fraction ≥65% at baseline echocard… Show more
