Assessing the Use of Left Atrial Strain Before and After Treadmill Exercise Stress Echocardiography.
Article in Echocardiography (Mount Kisco, N.Y.), 2025. 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
aimsLeft atrial strain (LAS) is a novel speckle-tracking technique used in the assessment of left atrial function. It has been shown to be a marker for adverse cardiac events (heart failure, myocardial ischemia, and atrial fibrillation). This study aimed to assess the role of LAS in assessing risk for diastolic dysfunction and myocardial ischemia in stress echocardiography (SE) before and after treadmill exercise. METHODS AND
resultsPatients undergoing routine Bruce protocol SE had LAS measurements (reservoir, conduit, and contractile strain) assessed before and after maximal treadmill exertion. Changes in LAS were measured and compared based on the result of the SE. Consecutive SE (n = 420) were analyzed (mean age 62 ± 5 years, 37% female). LAS was able to be estimated before and after stress in 367 patients, including 313 Normal SE, 32 Ischemic SE, and 22 Abnormal DST. All LAS measurements (reservoir, conduit, and contractile strain) increased significantly in Normal SE. The LAS measurements did not significantly change for patients with Ischemic SE and Abnormal DST. Using a receiver operator curve analysis and linear regression, apical 4-chamber reservoir LAS was found to be the best differentiator between Normal SE and abnormal tests (Ischemic SE and Abnormal DST).
conclusionChange in LAS before and after treadmill exercise differentiated Normal SE and abnormal SE (Ischemic SE and Abnormal DST). It may represent a novel non-invasive assessment for diastolic stress echocardiography.
