Improvements in left ventricular regional and global systolic function following treatment with S100A4-shRNA after myocardial infarction in mice.
Article in Quantitative imaging in medicine and surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundS100A4 plays a vital role in cardiac fibrosis after myocardial infarction (MI), but its effects on myocardial mechanics and remodeling are unknown. We hypothesized that regional and global left ventricular (LV) systolic function as determined by speckle tracking echocardiography (STE) would be improved with inhibition of S100A4 using short hairpin (sh) RNA. This study aimed to investigate whether STE can delineate the efficacy and safety of S100A4-shRNA in MI.
methodsA total of 48 mice were randomly assigned to sham+S100A4-shRNA, sham+scrambled (Scr) sequence-shRNA, MI+S100A4-shRNA, and MI+Scr-shRNA groups (n=12 per group) and underwent intramyocardial injection of target agents after MI was produced by left anterior descending ligation. Two-dimensional STE and M-mode echocardiography were performed at baseline and at day 7, 14, and 28 post-MI by GE Vivid 7 ultrasound (il3L linear probe, 10.0-14.0 MHz) and Echopac PC software. Radial strain was analyzed from 6 segments of the mid short axis images with 20-30 frames per cardiac cycle. Post-mortem western blotting, immunohistochemistry, and Masson's trichrome stain were performed to quantify infarct size and detect suppression of S100A4.
resultsSTE detected a statistically significant improvement in peak radial strain (pRS) and time to peak radial strain (pRSt) by day 14 post-MI in the MI+S100A4-shRNA group (P<0.05), especially in the LV anteroseptal wall (pRS: 23.83%±1.12%
conclusionsS100A4-shRNA can be utilized as a therapeutic target to improve regional deformation and attenuate cardiac fibrosis following MI. Two-dimensional STE is useful in the early and comprehensive assessment of LV systolic function in mice.
