Prognostic Value of Cardiac Strain in Cognitive Impairment: A Systematic Review.
Synthesis in Medical sciences (Basel, Switzerland), 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
BACKGROUND/
objectivesHeart failure (HF) increases the risk of cognitive impairment (CI). Consequently, early detection and prevention of HF progression may reduce the impact of cognitive decline. The employment of novel echocardiographic imaging techniques, such as myocardial function assessment via speckle tracking strain, allows for the detection of subclinical myocardial dysfunction. The objective of this study is to identify whether speckle tracking strain has the capacity to demonstrate early cardiac alterations in patients with CI.
methodsFollowing a systematic review across five databases, three studies utilizing left ventricular global longitudinal strain (GLS) and seven studies utilizing left atrial global strain (LAS) were included.
resultsIn the assessment of myocardial strain, the sample totaled 20,614 individuals, with a mean and median age of 70 years and a predominance of females (55.3%). Left atrial global strain was the myocardial deformation marker that most frequently demonstrated an association with cognitive impairment in the listed studies. Speckle tracking GLS also demonstrated differences between groups. Only one study found no association between sensitive measures of left ventricular and left atrial function and the presence of CI.
conclusionsIn conclusion, the results of this systematic review suggest that GLS and LAS are early markers of cognitive impairment.
