Acute effects of percutaneous coronary intervention on neutrophil activation and maturity markers in coronary and peripheral circulation.
Article in Open heart, 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
backgroundAcute inflammatory responses during and after percutaneous coronary intervention (PCI) are associated with subsequent cardiovascular event risk, but limited data exist on acute immune cell responses regulating PCI-related inflammation. As an exploratory pilot study, our objective was to determine whether PCI acutely alters neutrophil-specific components of activation, maturity and chemotaxis in the coronary and peripheral circulation.
methodsThis prospective cohort study was conducted from October 2024 to January 2025 within an urban tertiary-care academic medical centre. Twenty-nine consecutive patients ≥18 years of age undergoing clinically indicated PCI were included. Paired blood samples were collected immediately pre-PCI and post-PCI from the peripheral arterial sheath (peripheral circulation) and coronary guide catheter (coronary circulation).
resultsThe primary endpoints were pre-PCI to post-PCI changes in immature neutrophils (CD10
conclusionsIn patients undergoing PCI, we observed an acute increase in circulating neutrophil cell-specific activation and immaturity markers following PCI but no significant effects of PCI on neutrophil degranulation. Further research is needed to understand whether these effects contribute to long-term post-PCI outcomes and, if so, if neutrophil release and activation warrant targeting during PCI.
