Investigating Left Atrial Diameter and Heart Failure Onset in Middle-Aged and Elderly: A Retrospective-Prospective Study.
Article in Clinical cardiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundLeft atrium (LA) is an integral component of left heart remodeling, reflecting hemodynamics and ventricular status. It remains uncertain whether left atrial diameter (LAD) can be utilized for predicting and evaluating the occurrence of heart failure (HF) in middle-aged and elderly individuals.
methodsThe study aimed to explore the correlation between LAD and HF in middle-aged and elderly individuals, elucidating the timing of occurrence HF in relation to LAD. The retrospective-prospective study investigated 4025 patients who underwent echocardiography at Zhongshan Hospital's Cardiovascular Department from January 2015 to December 2017. Patients were continuously monitored for HF until January 31, 2024. Cox regression analyses related baseline LAD to HF incidence, adjusted for known risk factors.
resultsA total of 4025 individuals (mean age: 55 years, 45.29% male) were studied, spanning ages 45-91. Fifty-one developed HF during a median follow-up of 4.36 years. Cox regression model demonstrated the association between HF and LAD (HR = 5.721, 95% CI 3.768-8.687, p < 0.001) even after adjusting for covariates (age, weight, eGFR, HDL-C, lymphocyte count, systolic blood pressure, FPG, HbA1C, waist circumference, hip circumference, valvular disease history, atrial fibrillation history).
conclusionsThe link between LAD and future HF occurrence risk among middle-aged and older adults shows a dose-response pattern. This relationship persists post-adjustment for HF-related factors, highlighting the predictive value of LAD in forecasting HF incidence.
