The immune-cardiovascular metabolic circuitry in myocardial ischemia-reperfusion injury: from metabolic signal release to spatiotemporal reprogramming.
Review in Frontiers in immunology, 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
Myocardial ischemia-reperfusion injury (MIRI) remains a major driver of infarct expansion, adverse remodeling, and poor outcomes after reperfusion therapy, yet mechanism-based treatments remain limited. Emerging evidence suggests that MIRI is not simply the additive result of oxidative stress and sterile inflammation. Rather, it reflects a spatiotemporally organized imbalance in immune-cardiac metabolic communication. In this framework, cardiomyocytes, coronary microvascular endothelial cells, fibroblasts, and resident cardiac macrophages act as both injury targets and signal-emitting units. They release succinate, lactate, ATP, lipid mediators, and mitochondrial danger signals. Infiltrating neutrophils, monocytes/macrophages, and lymphocyte subsets decode these cues through reprogramming of glycolysis, oxidative phosphorylation, fatty acid oxidation, and amino acid metabolism. These responses shape inflammatory amplification, resolution, and tissue repair. This review summarizes key connecting mechanisms, including hypoxia sensing, mitochondrial dysfunction, and the axis linking adenosine monophosphate-activated protein kinase (AMPK), sirtuin 1 (SIRT1), and peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α). It also discusses immunometabolites such as succinate, lactate, itaconate, and ATP/adenosine as links between tissue injury and immune cell-state transitions. Finally, we highlight temporal windows, spatial niches, and cell-state specificity, and evaluate how single-cell omics, spatial transcriptomics, spatial metabolomics, and metabolic flux analysis may guide time-sensitive, subpopulation-specific, and spatially precise therapies.
