1 · What the graph read from it

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.

2 · The registry

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: The incidence of myocardial infarction (MI) and its adverse effects on health and mortality remain high in densely populated low- and middle-income countries (LMICs). To address the issue of densely populated areas and timely access to primary PCI, chest pain units (CPUs) were deployed at strategic locations in Karachi, with a populace of over 23 million people. This study describes the results of this initiative in expediting MI care. Methods: Between 2017 and 2023, 18 CPUs, each with a cardiologist, technician, ECG machine, crash cart and an ambulance were placed in high density areas. Findings: A total of 915,564 patients were seen at 18 CPUs over the study period. 692,444 (75.6%) were categorized as non-cardiac and subsequently discharged. 223,120 (24.6%) patients were directed for additional care. Of these, 9% had ST elevation myocardial infarction (STEMI) (19, 580), 29% NSTE ACS/Unstable angina, and 31% with various other cardiac conditions. Additionally, 31% were referred for medical outpatient evaluation. CPU inception led to a significant annual growth (16-20%) in primary PCI procedures at NICVD, totaling 20,000 by 2022-2023. The median first medical contact to device time was 100 min (IQR 80-135), while total ischemic was 232 min (IQR: 172-315; 5th -95th %le: 50-920). The overall in-hospital mortality rate for patients undergoing primary PCI was 5.58%, with a range between 5.1% and 6.9% through the study period. Interpretation: Novel standalone chest pain units, operational from 2017 in Karachi, Pakistan, have expedited triage and enhanced the timely management of AMI. This initiative's transformative impact presents a model that resonates beyond borders, serving as a role model for global healthcare systems. Funding: The CPU and primary PCI program is fully funded by the government of Sindh. No specific funding was allocated for this study.
