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.

Abstract

backgroundThe objective of this study was to investigate atrial myocardial properties through two-dimensional (2D) myocardial imaging in patients with atrial fibrillation (AF) and its predictive role for recurrence after catheter ablation. METHODS AND

resultsEchocardiographic examinations were performed in 40 patients with paroxysmal AF before catheter ablation and 40 age- and gender-matched healthy control subjects. Using a software package, bidimensional acquisitions were analyzed to measure longitudinal strain and strain rate for the left atrium (LA). Systolic strain and strain rate in all eight segments, and its average values, were significantly reduced in AF patients compared to controls. During 9 months of follow-up after catheter ablation for AF, 11 of 40 AF patients had AF recurrence. AF recurrence was associated with gender, LA volume index, and average values of systolic strain and strain rate. By multivariate analysis, only average strain was an independent predictor of AF recurrence (OR = 0.88, 95% CI 0.79-0.98, p = 0.018).

conclusionsLower systolic strain of LA was strongly associated with recurrence after catheter ablation. Thus, diverse adjunctive ablation strategies should be considered to reduce recurrence in patients with lower systolic strain.
