Evaluation of the relationship between inflammation and typical chest pain in ST-elevation myocardial infarction.
Article in Clinical proteomics, 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
backgroundPrevious investigations have shown that the absence of typical breast symptoms is associated with unfavorable outcomes after an acute myocardial infarction (AMI). Delayed diagnosis and therapy could not explain these results, so other causes seem to be involved. Therefore, in the present analysis the association between inflammatory plasma proteins and typical chest pain symptoms in hospitalized patients with acute ST-elevation myocardial infarction (STEMI) was investigated.
methodsData from 395 STEMI patients registered by the population-based Myocardial Infarction Registry Augsburg between 2009 and 2013 were used for analysis. The OLINK inflammatory panel including a total of 92 cytokines was measured in arterial blood samples, which were obtained immediately after hospital admission within the scope of cardiac catheterization. The associations between the inflammation markers and typical chest pain were examined by multiple logistic regression analyses.
resultsAltogether, 10.9% of the STEMI patients did not present with typical chest pain. The inflammatory markers IL8, IL6, FGF-21, CD40, CST5, ADA, OPG, PD-L1, TNFRSF9 and STAMBP were significantly inversely associated with typical chest pain after FDR-adjustment. The strongest associations were found for FGF-21, CST5 and CD40.
conclusionsThese results suggest that a dysregulated inflammatory status is associated with a lack of typical chest pain in AMI patients. Beyond acute-phase inflammatory interleukins elevated within the early phase of an AMI, such as IL-6, hepatokines and transmembrane proteins seem to be associated with AMI symptoms. Further research into the causal mechanisms of these associations is necessary.
