Ischemic Preconditioning Negatively Affects Thrombogenic Clotting Profile in Cerebral Small Vessel Occlusion Stroke Patients.

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
Background: The study evaluated the effect of an acute and a 2-week daily repetitive ischemic preconditioning (IPC) on conduit artery vascular function and thrombogenic clotting profile, in patients with a recent ischemic stroke. Methods: Fourteen patients, aged 71 ± 8 years, with a cerebral small vessel occlusion stroke were included in a randomized, controlled, open-label cross-over study. Treatment consisted of 2 weeks of daily IPC, four 5-min rounds of upper-arm occlusion, interspersed by 5 min rest periods. Control was without treatment. Brachial artery flow-mediated dilation (FMD) was determined at baseline and after the control and treatment periods. Before and after each period, the patients underwent an acute bout of IPC. Blood samples were obtained for thrombogenic clotting profile at baseline and after the acute IPC bout, both before and after the control and treatment periods. Results: The period of daily IPC increased brachial artery diameter but did not influence FMD. Acutely, IPC was found to induce an increase in fractal dimension, indicating a denser clot microstructure, and a reduction in plasma levels of plasminogen activator inhibitor 1 (PAI-1). There was no effect of daily IPC on the basal thrombogenic clotting profile, or on the change in clotting profile induced by acute IPC. Conclusions: Collectively, the data show that acute IPC leads to a prothrombotic clotting profile, despite antiplatelet therapy. Moreover, 2 weeks of daily treatment with IPC does not influence conduit artery vascular function or thrombogenicity in stroke patients.
