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

A series of brief ischemia/reperfusion cycles (termed ischemic preconditioning, IPC) limits myocardial injury produced by a subsequent prolonged period of coronary artery occlusion and reperfusion. Over the last 2 decades our understanding of IPC's mechanism has increased exponentially. Hearts exposed to IPC have a better metabolic and ionic status during prolonged ischemia compared to naïve hearts. However, this difference is not thought to be the main mechanism by which IPC protects against infarction. Signaling pathways that are activated by IPC distinguish IPC hearts from naïve hearts. During the trigger phase of IPC, adenosine, bradykinin and opioid receptors are occupied. Although these three receptors trigger signaling through divergent pathways, the signaling converges on protein kinase C. We have proposed that at the end of the index ischemia the activated PKC sensitizes the low-affinity A(2b) adenosine receptor (A(2b)AR) through phosphorylation of either the receptor or its coupling proteins so that A(2b)AR can be activated by endogenous adenosine released by the previously ischemic cardiomyocytes. The sensitized A(2b)AR would then be responsible for activation of the survival kinases including PI3 kinase, Akt and ERK which then act to inhibit lethal mitochondrial permeability transition pore formation which normally uncouples mitochondria and destroys many myocytes in the first minutes of reperfusion. Herein we review the evidence for the above mechanisms and their functional details.
