Left ventricular strain measured by feature-tracking cardiac magnetic resonance imaging and 2D speckle-tracking echocardiography in chronic ischemic heart disease: an intermodality agreement study.

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
backgroundGlobal longitudinal strain (GLS) is a valuable tool for assessing left ventricular (LV) systolic function, detecting subclinical dysfunction earlier than classic ejection fraction. Two-dimensional speckle-tracking echocardiography (2D-STE) is widely used due to its accessibility and high temporal resolution, whereas feature-tracking cardiac magnetic resonance (FT-CMR) offers superior spatial resolution and reproducibility. In this study, we assess the relationships between longitudinal strain measurements obtained by 2D-STE and FT-CMR in patients with chronic ischemic heart disease (IHD).
methodsFifty-five patients with IHD and left ventricular ejection fraction (LVEF) ≤ 49% underwent 2D-STE and FT-CMR at least 3 months after an acute coronary event. Global and segmental longitudinal strain for all 17 myocardial segments was measured using both modalities. Pearson correlation and Bland-Altman analysis were used to assess correlation and agreement, respectively.
resultsGLS showed a strong correlation between 2D-STE and FT-CMR (r = 0.793, P < 0.001), with a mean difference of 0.98% and limits of agreement from -3.2% to + 5.1%. Segmental strain demonstrated greater variability (r = 0.03 to 0.47), with the best agreement in mid and apical segments and greatest discrepancies at the basal level.
conclusionsIn patients with IHD and reduced LVEF, GLS obtained by FT-CMR and 2D-STE showed strong correlation and acceptable overall agreement. However, the relatively wide limits of agreement and variability in segmental strain, particularly in basal regions, indicate that the two methods are not fully interchangeable for individual assessment and follow-up. Both techniques reflect similar physiological trends but differ in absolute values, requiring caution in regional strain interpretation.
