AsistIAM: Innovating the Acute Coronary Syndrome Approach in Primary Care Settings.
Article in Clinical cardiology, 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
backgroundEarly management of acute coronary syndrome (ACS) is critical. Clinical guidelines are more consistently implemented in high-complexity hospitals; however, in rural and primary care settings multiple barriers limit timely diagnosis and treatment. This study aimed to develop and evaluate the usability of a mobile application designed to assist primary care physicians in the diagnostic approach and initial management of ACS.
methodsA mHealth tool named AsistIAM was developed with five modules: electrocardiogram pattern, reperfusion strategies, risk assessment, real-time georeferencing, and educational content. Usability was assessed on a 1-7 scale under in both simulated and real-world conditions. In the latter, a before-and-after study was performed with physicians from four rural primary healthcare centers and one referral hospital. In the pre-implementation phase, participants completed a survey identifying barriers to ACS care. After using the app, they complete the same survey to analyze changes.
resultsA total of 18 participants evaluated the app in simulated conditions and 59 in real-world settings. Mean usability scores were high (6.52, in simulation and 6.18 in real-world). The best-rated items were ease of learning, interface satisfaction, and availability of functions. After app implementation, physicians reported improvements in ECG acquisition and interpretation (81.4%-100%), recognition of ST-elevation patterns (25.6%-39.2%), identification of referral centers (88.1%-98.0%), and correct use of fibrinolytics (errors 44.1%-17.6%).
conclusionsAsistIAM represents an innovative tool to strengthen regional networks, improve ACS management and support timely clinical decision-making. Usability results highlight its intuitive interface, functionality, and practical utility.
