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

aimsThis study aims to assess long-term changes in left ventricular ejection fraction (LVEF) together with echocardiographic markers of cardiac remodelling and their association with prognosis and patient-reported quality of life (QoL). METHODS AND

resultsWe conducted a retrospective analysis of serial echocardiograms performed between January 2009 and December 2019 in 1089 patients (median age 63 years, 71.0% men) enrolled in the Mazankowski Heart Function Clinic Registry who had at least two echocardiograms separated by ≥12 months. We classified the patients into four subgroups by their baseline and LVEF trajectories: persistent heart failure with reduced ejection fraction (persistent HFrEF, n = 364), recovered ejection fraction (HFrecEF, n = 325), transient recovery in ejection fraction (HFtrecEF, n = 117), and preserved ejection fraction (HFpEF, n = 283); 4490 echocardiograms were included in the present analysis, with 4.1 ± 1.8 echocardiograms available per patient during follow-up. Reductions in echocardiographic markers of cardiac remodelling, including LVIDd [adjusted odds ratio (aOR): 2.22, 95% confidence interval (CI) 1.75-2.86], LVIDs (aOR: 2.44, 95% CI 2.00-2.94), left ventricular mass index (aOR: 1.15, 95% CI 1.09-1.22), E/e' ratio (aOR: 1.15, 95% CI 1.02-1.30), left atrial volume index (aOR: 1.10, 95% CI 1.03-1.16), along with an increase in the maximum recommended daily dose of renin-angiotensin system inhibitors (aOR: 1.04, 95% CI 1.01-1.07) and mineralocorticoid-receptor antagonists (aOR: 1.06, 95% CI 1.01-1.11) at 2 years, strongly predicted the HFrecEF classification, which was further sustained at 5 years of follow-up. However, changes in these parameters were mostly absent in patients experiencing only a transient recovery in LVEF (HFtrecEF), closely resembling patients with persistent HFrEF. In the multivariable analysis, HFrecEF patients had lower risk of all-cause mortality alone [adjusted hazard ratio (aHR): 0.46, 95% CI 0.23-0.93], and composite all-cause (aHR: 0.59, 95% CI 0.49-0.73), cardiovascular (aHR: 0.47, 95% CI 0.36-0.61), and heart failure (aHR: 0.50, 95% CI 0.35-0.70) related hospitalizations with mortality than patients with persistent HFrEF. QoL assessed through the shortened Kansas City Cardiomyopathy Questionnaire-12 at the end of follow-up was greater in patients with HFrecEF by 5.2, 12.4, and 9.4 points than persistent HFrEF, HFtrecEF, and HFpEF, respectively.

conclusionsPatients with HFrecEF experienced progressive normalization in echocardiographic markers of cardiac remodelling characterized by reductions in left ventricular dimensions and mass in tandem with reductions in left atrial volume and E/e' ratio, which is associated with better prognosis and QoL.
