Acute Immune Cell Dynamics During Myocardial Infarction and Their Association with Mortality.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Acute neutrophil responses following myocardial infarction (MI) play a central role in remodeling, contributing to both repair and potential maladaptive responses. Although prior studies have investigated circulating immune cell indices at a single time point during hospitalization for MI, limited data exist on acute intra-individual changes in circulating immune profiles during evolving MI. We analyzed clinical measurements, such as the count and proportion of immune cell components in a serial complete blood count, with differential tests conducted for patients hospitalized with ST-elevation MI (STEMI) in various hospitals in the Northwestern Medicine system from 1 January 2002 to 1 August 2024. Patients with STEMI diagnosis, troponin peaks ≥ 5 ng/mL, and cell count and proportion data prior to the troponin peak and within 24 h after the troponin peak were included. Primary analyses investigated the associations between the troponin peak and peri-STEMI changes in immune cell subsets. Multivariable-adjusted Cox models were used to investigate associations between these peri-STEMI immune cell changes and mortality at 1 year and 3 years. Among the 694 STEMI patients meeting the inclusion criteria, a higher troponin peak was associated with a modest peri-MI increase in neutrophil proportion. Higher adjusted peri-STEMI increases in neutrophil count and proportion were strongly associated with mortality at one and three years [hazard ratio (HR) = 1.31 (95% confidence interval (CI) 1.15-1.49) and HR = 1.27 (95% CI 1.14-1.45) per 1000 cells/μL absolute neutrophil increase, respectively]. Individuals with higher STEMI-related neutrophil increases had higher mortality at one year and three years, independent of the extent of troponin elevation.
