WebJan 1, 2024 · NMF identified three HFpEF transcriptomic subgroups with distinctive pathways and clinical correlates, including a group closest to HFrEF with higher mortality, and a mostly female group with smaller hearts and pro-inflammatory signaling. These groupings remained after sex adjustment. WebHeart failure with preserved ejection fraction (HFpEF) is a complex syndrome with preserved systolic function but diastolic stiffening that contributes to filling abnormalities. The culmination of these changes is left ventricular (LV) hypertrophy, decreased cardiac reserve, and pulmonary edema ( Norman et al., 2011; Borlaug, 2014 ).
