1 · What the graph read from 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.

2 · The registry

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

Aims: Pathological left ventricular (LV) remodelling following aortic stenosis (AS) confers high risk for heart failure and significantly decreases survival. This study aims to introduce a new wearable acoustic cardiography (ACG) device measuring electromechanical activation time (EMAT) to identify the regression of cardiac remodelling in AS patients undergoing transcatheter aortic valve replacement (TAVR). Methods and results: This prospective cohort study consecutively enrolled patients with severe symptomatic AS who underwent successful TAVR. The parameters EMAT and EMAT% (EMAT divided by R-R interval, expressed as a percentage) derived from ACG as well as echocardiography data were collected. Pearson correlation analysis was performed to evaluate the correlation between EMAT% and left ventricular mass index (LVMi). Receiver operating characteristic (ROC) curves were used to assess the diagnostic performance of EMAT% in predicting left ventricular hypertrophy (LVH). A total of 159 patients (mean age 72.0 years) were enrolled in the study. At baseline, 55% of patients demonstrated severe LV remodelling. Scatter plots and Pearson correlation analysis revealed a significant association between EMAT% and LVMi. The ROC curve analysis showed strong diagnostic performance of EMAT% in predicting LVH, with an area under the curve consistently exceeding 80% at baseline and during follow-up. Both EMAT% and echocardiographic parameters indicated that LV remodelling progressively improved between 1 and 6 months after TAVR, with stabilization observed at 12 months. Conclusion: The EMAT can be considered as an effective tool to assist in the evaluation of LV remodelling after TAVR. Further studies are required to confirm its utility as a valuable non-invasive diagnostic and monitoring tool.
