Unravelling the Pathogenesis of Heart Failure with Preserved Ejection Fraction: The Pivotal Role of Autophagy and Endoplasmic Reticulum Stress.
Review in European cardiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Heart failure with preserved ejection fraction (HFpEF) accounts for nearly half of all heart failure cases and is associated with high morbidity and mortality. Despite its prevalence, effective therapies remain elusive due to its complex and multifactorial pathophysiology, including systemic inflammation, microvascular dysfunction, myocardial fibrosis and diastolic dysfunction. Recent evidence has highlighted the central role of cellular stress responses (particularly autophagy and endoplasmic reticulum stress) in the progression of HFpEF. This review examines current evidence on the roles of autophagy and endoplasmic reticulum stress in HFpEF, focusing on their interplay and associated biomarkers, including light chain 3 (LC3), Beclin-1, GRP78 and CHOP. Dysregulated autophagy and endoplasmic reticulum stress have been shown to promote vascular senescence, inflammation, fibrosis and further remodelling in HFpEF. The targeting of autophagy and endoplasmic reticulum stress offers new diagnostic and therapeutic avenues. Future research should prioritise biomarker development and personalised therapies to shift HFpEF management from symptom control to molecular targeting.
