Pharmacological treatments and clinical events in newly diagnosed heart failure patients stratified by ejection fraction in Japan.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
There is a limited understanding of the uptake of pharmacological treatments and incidence of clinical events in newly diagnosed heart failure (HF) patients, stratified by left-ventricular ejection fraction (LVEF) in contemporary clinical settings in Japan. A retrospective cohort study was conducted using a nationwide Japanese hospital database to evaluate the patterns of HF medications and clinical events in adult patients with a first confirmed HF diagnosis from January 1, 2020-July 31, 2023 (n = 16,001). Fine-Gray sub-distribution hazard models were applied to assess factors associated with HF medication initiations and clinical events. Overall, 5473 (34.2%), 3053 (19.1%), and 7475 (46.7%) patients with HF with reduced ejection fraction, mildly reduced ejection fraction (HFmrEF), and preserved ejection fraction (HFpEF) were included, respectively. Within the first 6 months, prescription rates of HF medications were: angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, or angiotensin receptor blocker-neprilysin inhibitor (65.6%), beta-blockers (57.6%), mineralocorticoid antagonists (55.7%), and sodium-glucose cotransporter-2 inhibitors (33.2%), with the lowest rates in HFpEF patients. The increase in prescription rates between 6 and 12 months was modest across all medication classes. One-year incidence rates per 100 person-years (95% confidence interval) of in-hospital all-cause mortality and in-hospital cardiovascular death were 23.0 (22.1-24.0) and 16.6 (15.8-17.4), respectively. HFmrEF and HFpEF were associated with lower hazards of treatment initiation for most HF medications, whereas the risks of in-hospital all-cause mortality and in-hospital cardiovascular death did not differ significantly across all LVEF subtypes. The findings underscore the suboptimal uptake of pharmacological treatments, despite the poor prognosis of newly diagnosed HF patients. The disparities in initiations of recommended treatments reaffirm the importance of properly implementing evidence-based therapies within each LVEF subtype.
