Frailty as an independent predictor of one-year outcomes in patients with HFpEF after acute myocardial infarction: insights from a multicenter retrospective cohort in China.
Article in Journal of geriatric cardiology : JGC, 2025. 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
backgroundHeart failure with preserved ejection fraction (HFpEF) following acute myocardial infarction (AMI) carries substantial morbidity and mortality, yet reliable prognostic markers beyond conventional cardiovascular factors remain limited. Frailty, reflecting diminished physiological reserve, has emerged as a potential determinant of adverse outcomes in this high-risk population. Therefore, the aim of this study was to address a critical knowledge gap and to provide evidence that may guide frailty-adapted management strategies to improve prognosis and quality of life in this high-risk population.
methodsWe conducted a multicenter retrospective cohort study including 4507 patients with HFpEF discharged after AMI across 82 hospitals in China (from January 2010 to March 2024). Frailty was assessed using the Hospital Frailty Risk Score (HFRS), with HFRS < 5 defined as non-frail and HFRS ≥ 5 as frail. Multivariable Cox proportional hazards models, adjusted for demographics, comorbidities, left ventricular ejection fraction, and therapies, were applied to evaluate associations between frailty and clinical outcomes. The primary endpoints were all-cause death and major adverse cardiovascular events (MACE), which defined as the composite of cardiovascular death and heart failure rehospitalization. Secondary endpoints included net adverse clinical events (NACE), which defined as the composite of all-cause death, stroke, recurrent myocardial infarction, revascularization, and major bleeding, as well as the individual components of MACE.
resultsFrailty was independently associated with a higher risk of all-cause death [adjusted hazard ratio (aHR) = 1.52, 95% CI: 1.31-2.03,
conclusionsFrailty, as measured by the HFRS, is an independent predictor of one-year mortality and composite adverse events in post-AMI HFpEF patients. These findings support the use of HFRS at discharge to identify high-risk population who may benefit from closer follow-up, optimization of medical therapy, and targeted frailty-focused interventions.
