Improving the management of acute myocardial infarctions: There's an App for that.
Article in American heart journal plus : cardiology research and practice, 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
Background: ST-Elevation Myocardial Infarction (STEMI) is a critical emergency. Managing care requires accurate diagnosis, shared communication between decision-makers, and timely transport and reperfusion at a hospital with capacity for such interventions. This study examines the implementation of a smartphone application (SMART AMI-ACS App) to facilitate real-time ECG sharing, enhancing communication and decision-making in STEMI management. Methods: This multi-centre study evaluated the implementation, acceptability and uptake of the App among interventional cardiologists and emergency medicine (EM) physicians managing suspected STEMI patients between April 1st 2022 and March 31st 2023. Guided by the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework, STEMI registry data and post-implementation surveys from a large regional cardiac centre and its 13 partner emergency departments in Ontario, Canada, were used to assess App uptake and effectiveness. Results: During the 12-month evaluation 254 (84 %) of the eligible 300 regional EM physicians downloaded the App, with > 1400 ECG images sent from 724 patients. Users reported the App helped in communication and timing of care. No degradation of ECG images was observed. App use was associated with lower door-in-door-out (DIDO) times 48 min (IQR 31-67) vs 55 min (IQR 39-77) and lower proportion of non-STEMI cases accepted to interventional cardiology (22 % vs 39 %, Conclusion: Uptake of the SMART AMI-ACS App was positive and may be associated with lower non-STEMI cases and lower DIDO times. The App provided a secure channel for communication of information and point-of-care transfer of images across healthcare providers. Uptake of the App has expanded to other regions.
