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

Ischemic preconditioning (IPC) is a protective phenomenon in which brief ischemia renders the myocardium resistant to subsequent ischemic insults. Here, we used A(2B)AR gene knock-out (A(2B)KO)/β-galactosidase reporter gene knock-in mice and the A(2B)AR antagonist ATL-801 to investigate the potential involvement of the A(2B)AR in IPC, focusing on the acute phase of protection. Cardioprotection provided by acute IPC elicited by two 3-min occlusion/3-min reperfusion cycles was readily apparent in an isolated, Langendorff-perfused mouse heart model in studies using hearts from A(2B)KO mice. IPC equivalently improved the recovery of contractile function following 20 min of global ischemia and 45 min of reperfusion in both WT and A(2B)KO hearts by ~30-40%, and equivalently decreased the release of cardiac troponin I during the reperfusion period (from 5969 ± 925 to 1595 ± 674 ng/g and 4376 ± 739 to 2278 ± 462 ng/g using WT and A(2B)KO hearts, respectively). Similarly, the infarct size-reducing capacity of acute IPC in an in vivo model of infarction was fully manifested in experiments using A(2B)KO mice, as well as in experiments using rats pretreated with ATL-801. We did observe, however, a marked reduction in infarct size in rats following administration of the selective A(2B)AR agonist BAY 60-6583 (~25% reduction at a dose of 1.0mg/kg). While supportive of its concept as a cardioprotective receptor, these experiments indicate that the mechanism of the early phase of IPC is not dependent on signaling by the A(2B)AR. We present the idea that the A(2B)AR may contribute to the later stages of IPC dependent on the induction of stress-responsive genes.
