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

backgroundRadiofrequency catheter ablation (RFCA) is a widely employed method for restoring sinus rhythm(SR) in patients with drug-refractory paroxysmal atrial fibrillation (PAF). Three-dimensional speckle tracking echocardiography (3DSTE) is a precise and practical imaging technique for clinically assessing myocardial function in the left atrium. The objective of this study was to assess alterations in three-dimensional strains and predict recurrence in patients with PAF following RFCA.

methodsA total of 109 patients diagnosed with drug-refractory PAF and scheduled for RFCA were included in this study between September 2019 and June 2022. Conventional echocardiography and 3DSTE were performed prior to and one year(median period of 12.2 months) after RFCA. Global three-dimensional left atrial (LA) strain parameters, along with those of the left ventricle, were measured and analyzed statistically. The primary study endpoint was the recurrence of atrial fibrillation (AF).

resultsAmong the 109 patients, 78 maintained a stable SR during the one-year follow-up after RFCA, while 31 experienced a recurrence of AF. Notably, patients who sustained SR demonstrated significant improvements in various LA strain parameters, including reservoir, pump, and conduit functions, compared to both their preoperative levels and those of patients who experienced recurrence(p < 0.05). Additionally, patients with sustained SR exhibited a significant reduction in LA volume compared to those with recurrence(p = 0.003). Furthermore, left ventricular global longitudinal strain (LVGLS) and left ventricular global area strain (LVGAS) of the left ventricle showed improvement while maintaining a preserved left ventricular ejection fraction (LVEF) after RFCA(p < 0.05). Our multivariate regression analysis revealed that left atrial reservoir strain (LASr) independently predicted the recurrence of AF [odds ratio (OR), 1.19, 95% confidence interval (CI), 1.05-1.35, p = 0.005]. Receiver operating characteristic(ROC) curve showed that the area under the curve(AUC) for LASr in assessing the risk of recurrence after RFCA in patients with PAF was 0.70 ( 95% CI, 0.60-0.81, P = 0.001). The calculated cutoff value was 16.5%.

conclusionsRFCA plays a pivotal role in preserving SR and restoring LA function in patients with PAF. 3D-STE is highly effective for post-RFCA prognostic assessment. LASr, a predictive marker for the recurrence of PAF assists in the stratification of risk and contributes to informed treatment decisions, offering valuable points of reference.
