Different types of exercise and myocardial angiogenesis regulation: A scoping review of cardiac-specific evidence in animal models.
Article in Physiological reports, 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
Exercise promotes myocardial angiogenesis, yet molecular responses vary by modality, and cardiac-specific evidence in healthy models remains fragmented. This study aimed to map biomolecular regulators of myocardial/coronary angiogenesis across exercise types in healthy animal models. PRISMA-ScR scoping review. Literature searches were conducted in PubMed, Scopus, and SpringerLink. Eligible studies were structured exercise interventions in physiologically healthy animals reporting myocardial/coronary tissue angiogenesis biomarkers and/or structural microvascular indices; disease models and studies reporting only circulating markers were excluded. FITT parameters and outcomes were charted and synthesized by exercise type. From 4674 records, 23 studies were included across swimming, continuous treadmill/running, interval/HIIT, resistance, and combined training. Aerobic protocols most consistently upregulated the VEGF-VEGFR axis with downstream PI3K/Akt-eNOS/NO and context-dependent HIF-1α signaling. Interval/HIIT showed prominent endothelial activation (e.g., miR-126 and CD34/KDR) alongside increased vascular indices. Resistance/combined training was less represented, but implicated AMPK-PGC-1α/FNDC5-irisin signaling, VEGFR2/FLK-1 upregulation, and eNOS/NO support in combined protocols. Exercise modality appears to recruit distinct upstream regulators that converge on myocardial angiogenic remodeling; evidence is dominated by male-only models, and mechanistic data for resistance/combined training remain limited.
