Metabolomic Analysis of the Effects of Canagliflozin on HFpEF Rats and Its Underlying Mechanism
Article in Endocrine, metabolic & immune disorders drug targets, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundHeart failure with preserved ejection fraction (HFpEF) represents a challenging cardiovascular condition characterized by normal systolic function but impaired diastolic performance. Despite its increasing prevalence, therapeutic options remain limited. This study investigated the metabolic effects of canagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, on cardiac function and energy metabolism in HFpEF.
methodsWe established a rat model of HFpEF using Dahl salt-sensitive rats and evaluated three experimental groups: control (A), HFpEF (B), and canagliflozin-treated HFpEF (C). This study carried out comprehensive analyses of cardiac structure and function, metabolomic profiling, and detailed assessment of myocardial energy metabolism, including mitochondrial respiratory capacity and ATP synthesis. Additionally, we validated our findings using H9C2 cardiomyocytes under controlled conditions.
resultsCanagliflozin treatment significantly improved cardiac remodeling markers, including reduced myocardial volume and fibrosis area, while enhancing diastolic function (E/A ratio). Metabolomic analysis revealed normalization of hypermetabolic states, with significant reductions in key metabolites, including L-lysine, D-glucose, and uridine. The treatment restored balance in multiple metabolic pathways, particularly affecting β-alanine metabolism, pyrimidine metabolism, and the citrate cycle. Notably, canagliflozin enhanced mitochondrial respiratory function, increased ATP synthesis, and optimized fatty acid utilization, as evidenced by reduced free fatty acid content.
conclusionOur findings demonstrated that canagliflozin exerts cardioprotective effects through multiple metabolic pathways, suggesting its potential as a therapeutic option for HFpEF. The ability of the drug to optimize energy metabolism and improve mitochondrial function represents a novel mechanism for treating this challenging condition.
