Impaired cardiomyocytes accelerate cardiac hypertrophy and fibrosis by delivering exosomes containing Shh/N-Shh/Gli1 in angiotensin II infused mice.

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
Backgrounds: Heart failure (HF) is characterized by progressive cardiac hypertrophy and fibrosis, yet the underlying pathological mechanisms remain unclear. Exosomes are pivotal in cellular communication and are key signaling carriers in HFs. This study investigated the roles of exosomes in HF. Methods: Eight-week-old male mice were divided into three groups: a control group, an Ang II group receiving angiotensin II (Ang II) infusion for 4 weeks, and an Ang II + DMA group receiving Ang II and dimethyl amiloride (DMA) infusion. This study examined the associations between cardiac injury, exosomes, and their substrate Shh. Furthermore, we conducted cellular experiments to assess the effects of Ang II-induced injury in primary cardiomyocytes on other cardiomyocytes and fibroblasts, and to test the therapeutic effects of the exosome inhibitor DMA and the Shh signaling inhibitor cyclopamine (CPN). Results: Ang II-induced cardiac hypertrophy and fibrosis, which were accompanied by exosome secretion and Shh upregulation Conclusions: Ang II-induced cardiomyocyte injury leads to cardiac hypertrophy and fibrosis through the release of exosomes carrying Shh signaling. The suppression of exosome secretion or the Shh pathway could offer new strategies for treating HF.
