Systemic Inflammation and Adverse Heart Failure Outcomes: Insights From the Veterans Affairs Health Care System.
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
backgroundThe association between systemic inflammation (SI) and outcomes among patients with heart failure with preserved ejection fraction (HFpEF) or mildly reduced ejection fraction (HFmrEF) is uncertain.
objectivesThis study aimed to evaluate the association between SI and clinical and economic outcomes among individuals with HFpEF/HFmrEF.
methodsWe identified Veterans with HFpEF/HFmrEF with outpatient high-sensitivity C-reactive protein (hsCRP) testing from 2008 to 2022. We classified Veterans as with SI (hsCRP 2-10 mg/L) and without SI (hsCRP <2 mg/L). The primary outcome was the 3-component major adverse cardiovascular event (MACE) outcome of death, HF hospitalization, and HF-related emergency department encounters. Additional outcomes included acute care utilization and costs. We evaluated the adjusted associations between SI and clinical outcomes, acute care utilization, and costs via Cox regression, negative binomial regression, and gamma regression, respectively.
resultsWe identified 49,986 Veterans with HFpEF/HFmrEF with outpatient hsCRP levels. We compared 8,696 (17.4%) Veterans without SI (hsCRP <2 mg/L) and 25,352 (50.7%) Veterans with SI (hsCRP ≥2 mg/L and ≤10 mg/L Over a median follow-up of 3.4 years (IQR: 1.8-5.8), MACE incidence was 15.1/100 patient-years (95% CI: 14.9-15.4) among those with SI vs 11.8/100 patient-years (95% CI: 11.4-12.1) among those without SI (P < 0.001). After adjustment, SI was associated with increased MACE (HR: 1.28; 95% CI: 1.24-1.33). SI was also associated with increased all-cause hospitalizations (incidence rate ratio: 1.19; 95% CI: 1.137-1.246) and $9,112 (95% CI: $6,135-$12,089) in additional per-patient costs over 1 year.
conclusionsAmong Veterans with HFmrEF/HFpEF, SI is associated with increased adverse clinical outcomes and higher costs.
