Integrated Myocardial and Plasma Lipidome Across the Human Obesity-Heart Failure Spectrum.
Article in Research square, 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) has become the dominant heart failure phenotype, with many patients impacted by marked obesity. Lipid dyshomeostasis is thought to contribute, but human myocardial lipidomic data remain lacking. We performed untargeted lipidomics (>1,000 species) of ventricular samples for non-failing (NF) controls (n=40), HFpEF (n=29), and HFrEF (n=13) patients, integrating results with myocardial transcriptomics, ultrastructure, and plasma lipidomics, across a broad obesity spectrum. Multiple lipid classes increased in HFpEF myocardium including phospholipids, sphingolipids, neutral lipids, and free fatty acids, but acylcarnitines declined. HFrEF had far fewer lipid changes, and cardiolipin and phosphatidylethanolamine depletion. Lipids were minimally altered in NF hearts from obese individuals. Plasma lipidomics identified few inter-group disparities. Heart lipidomics from major animal HFpEF models (high fat diet+L-NAME, ZSF-1 rat, obese-DOCA-salt pig) all differed from human HFpEF. Thus, human HFpEF myocardium has distinctive cardiac lipid accumulation not found with obesity alone or HFrEF, nor mirrored by common preclinical HFpEF models.
