Association between left ventricular longitudinal function and left atrial strain in left ventricular dysfunction.
Article in ESC heart failure, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
introductionLeft ventricular (LV) longitudinal function is a prognostic marker of hospitalization and mortality in LV dysfunction. Recently, left atrial (LA) reservoir and conduit strain have also been presented as independent prognostic markers. However, the atria and ventricles are coupled in the fibrous atrioventricular plane (LA-LV coupling). The degree to which the LA strain is affected, or even determined, by the LV longitudinal function in LV dysfunction has been explored by echocardiography, but not by cardiac magnetic resonance imaging (CMR). Therefore, we aimed to quantify the association between LV longitudinal ventricular function and LA strain using CMR feature-tracking.
methodsThree hundred and forty-two patients with LV dysfunction (including heart failure with reduced ejection fraction (HFrEF), candidates for cardiac resynchronization therapy (CRT) implantation, and ischaemic heart disease (IHD)), and 19 healthy controls (HC) who had undergone CMR were retrospectively included. LV global longitudinal strain (LV-GLS), LV atrioventricular plane displacement (AVPD), and LA-GLS (i.e. reservoir strain) were analysed in long-axis views using CMR feature-tracking.
resultsLA-GLS was lower in the LV dysfunction group when compared to HC (12 ± 8% vs 19 ± 7, P < .001), mirroring reductions in LV-GLS (-10 ± 5% vs -19 ± 3, P < .001), and LV-AVPD (9 ± 3 vs 15 ± 2 mm, P < .001). The coefficient of determination (r2) between LV-GLS and LA-GLS was .40 (95% CI 0.32-0.48) for the whole cohort, and 0.39 (95% CI 0.31-0.47) between LV-AVPD and LA-GLS.
conclusionIn a large cohort comprising both patients with LV dysfunction and HC, LA reservoir function quantified as LA-GLS was to a large extent determined by LV longitudinal function. LA function may not be an independent marker of global cardiac function for certain patient groups where diminished LA function can be a reflection of LV dysfunction.
