Identification of novel pheno-groups in heart failure with preserved ejection fraction using machine learning.

<h4>Objective</h4>Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome. We aimed to derive HFpEF phenotype-based groups ('phenogroups') based on clinical and echocardiogram data using machine learning, and to compare clinical characteristics, proteomics and outcomes acr...
