Early detection of left atrial dysfunction in young hypertensive patients with a normal left atrial size: a comprehensive analysis using four-dimensional auto left atrial quantification echocardiography.
Article in BMC cardiovascular disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThis study aimed to detect early left atrial (LA) function abnormalities in young hypertensive patients with a normal two-dimensional LA volume index (2D-LAVI) using four-dimensional auto LA quantification technology (4D Auto LAQ) and to analyse correlations between LA strain parameters and clinical metabolic indicators.
methodsThis study enrolled 70 young patients who underwent standard hypertension treatment or diagnosis at the Second Affiliated Hospital, Jiangxi Medical College, Nanchang University, from October 2023 to July 2024 and 41 control volunteers enrolled during the same period. LA volume and strain parameters were evaluated with a 4D Auto LAQ. A correlation analysis was conducted between the clinical and strain parameters.
resultsCompared with the control group, young hypertensive patients presented significantly greater LA minimum volume (LAVmin), LA minimum volume index (LAVImin) and LA pre-atrial volume (LAVpreA) values (all p < 0.001). The LA ejection fraction (LAEF) was reduced in young hypertensive patients (57.85%±4.47% vs. 50.44%±5.96%, p < 0.001), along with LA reservoir longitudinal strain (25.00% [20.50-29.50%] vs. 20.00% [16.00-24.25%], p < 0.001), LA conduit longitudinal strain (-16.32%±4.19% vs. -11.37%±4.65%, p < 0.001), LA contraction longitudinal strain (-12.27%±2.85% vs. -9.60 ± 4.12, p < 0.001), LA reservoir circumferential strain (34.32%±6.90% vs. 28.41%±6.95%, p < 0.001), LA conduit circumferential strain (-17.90%±4.84% vs. -11.46%±4.96%, p < 0.001), and LA contraction circumferential strain (-18.54%±4.85% vs. -16.23%±6.11%, p < 0.05). Multivariate linear regression analysis revealed that body mass index (BMI), triglyceride (TG), and uric acid (UA) were negatively and independently correlated with LA longitudinal strain.
conclusionsIn young hypertensive patients with normal 2D-LAVI, while LAVmin, LAVImin and LAVpreA are elevated, the LAEF and LA reservoir, conduit, and contraction strain are notably reduced. The application of 4D Auto LAQ technology may highlight altered values in young hypertensive patients with normal 2D-LAVI. 4D Auto LAQ may serve as a valuable tool for clinicians in the early detection and assessment of LA dysfunction in young hypertensive patients.
