Risk stratification according to diastolic function indices in heart failure patients with mildly reduced or reduced ejection fraction.
Article in European heart journal open, 2023. 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
Aims: The aim of the study is to evaluate the risk of all-cause mortality or heart failure hospitalizations in ambulatory patients with heart failure with reduced and mildly reduced ejection fraction (HFrEF or HFmrEF) according to diastolic function indices. Diastolic dysfunction in HF is both common and associated with poor prognosis. However, specific cut-off values of diastolic function parameters for prognostication of hard outcomes in HF have not been conclusively established. Methods and results: Analysis of full echocardiographic examination of consecutive ambulatory HFrEF and HFmrEF patients seen at a single tertiary hospital between 2010 and 2021 was retrospectively done. Data on all-cause mortality or heart failure hospitalizations were obtained from the electronic medical records and national mortality registry. Patients with > moderate left heart valvular dysfunction were excluded from the study. The final cohort included 4717 patients (75% males, median age 70 years interquartile range 61.3-78.4). After adjusting for clinical or echocardiographic variables, increased rates of mortality or HF hospitalizations were found when Conclusion: In patients with HFmrEF and HFrEF, slightly abnormal diastolic indices were found to be associated with worse outcomes. Summary: We have demonstrated that in patients with heart failure with reduced and mildly reduced ejection fraction (HFrEF or HFmrEF), near-normal diastolic indices are associated with worse outcomes with the following cut-off values: max E-wave velocity > 0.78 m/s,
