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

objectiveThe ischemic myocardium releases multiple chemotactic factors responsible for the mobilization and recruitment of bone marrow-derived cells to injured myocardium. However, the mobilization of primitive pluripotent stem cells (PSCs) enriched in very small embryonic-like stem cells (VSELs) in various cardiac ischemic scenarios is not well understood. MATERIALS AND

methodsFifty-four ischemic heart disease patients, including subjects with stable angina, non-ST elevation myocardial infarction, and ST elevation myocardial infarction (STEMI) and 12 matched controls were enrolled. The absolute numbers of circulating stem/primitive cells in samples of peripheral blood (PB) were quantitated by ImageStream analysis and conventional flow cytometry. Gene expression of PSC (Oct-4 and Nanog), early cardiomyocyte (Nkx-2.5 and GATA-4), and endothelial (von Willebrand factor) markers was analyzed by real-time polymerase chain reaction.

resultsThe absolute numbers of PSCs, stem cell populations enriched in VSELs, and hematopoietic stem cells present in PB were significantly higher in STEMI patients at presentation and declined over time. There was a corresponding increase in pluripotent, cardiac, and endothelial gene expression in unfractionated PB cells and sorted PB-derived primitive CD34(+) cells. The absolute numbers of circulating VSELs and hematopoietic stem cells in STEMI correlated negatively with patient age.

conclusionsMyocardial ischemia mobilizes primitive PSCs including pluripotent VSELs into the circulation. The peak of mobilization occurs within 12 hours in patients presenting with STEMI, which may represent a therapeutic window for future clinical applications. Reduced stem cell mobilization with advancing age could explain, in part, the observation that age is associated with poor prognosis in patients with myocardial infarction.
