Prevalence and Prognostic Significance of Frailty in Elderly Patients With Severe Valvular Heart Diseases.
Article in JACC. Advances, 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
backgroundFrailty is a known predictor of adverse outcomes in aortic valve replacement. However, its impact on the broader population with valvular heart disease (VHD) remains less explored.
objectivesThis study aimed to evaluate the prevalence of frailty across major VHD subtypes and investigate the association between frailty and adverse clinical events.
methodsA total of 2,147 elderly patients with severe VHD from the China-DVD2 Study underwent the frailty assessment using the Fried, Fried+, Essential Frailty Toolset, and a simplified 4-item score. The primary outcome was a 1-year all-cause death, whereas the secondary outcome was 1-year all-cause death and heart failure hospitalization.
resultsThe median age was 72.8 years (43.5% female). Frailty prevalence ranged from 16.8% to 39.3% and prefrailty from 50.9% to 64.5%, depending on the assessment tool. Among the evaluated scales, the simplified frailty score was the most consistent association with adverse outcomes (adjusted HR: 1.50 [95% CI: 1.25-1.81] for all-cause mortality; 1.53 [95% CI: 1.32-1.77] for the composite outcome). These associations were preserved across the exploratory subgroups and specific VHD subtypes. Adding frailty score to the European System for Cardiac Operative Risk Evaluation II improved risk stratification for all-cause mortality (C-statistic: 0.715 vs 0.668; likelihood ratio test P < 0.001) and the composite outcome (0.722 vs 0.688; likelihood ratio test P < 0.001).
conclusionsFrailty is highly prevalent and independently associated with poor prognosis in severe VHD. The simplified 4-item frailty score offers a practical and incrementally valuable tool for enhancing risk stratification in routine clinical practice.
