Red blood cell metrics as predictors of cardiovascular risk in anemic versus non-anemic heart failure patients.
Article in BMC cardiovascular disorders, 2026. 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
backgroundChronic heart failure is a growing health concern globally, with rising prevalence and considerable social and economic impact as a leading cause of death. Although significant progress has been made in cardiovascular disease treatment over the last two decades, this condition continues to pose a significant clinical challenge. The connection between red blood cell parameters and major cardiovascular complications in patients with chronic heart failure remains poorly understood. Assessing these metrics could enhance our ability to predict long-term cardiovascular outcomes in this patient population. MATERIALS AND
methodsIn this single-center, retrospective analysis of a prospective cohort, 419 chronic HF patients (mean age 63.70 ± 11.67 years) were enrolled between 2023 and 2024 and categorized into anemic (n = 251) and non-anemic (n = 168) groups based on WHO hemoglobin criteria. Baseline demographic, clinical, and hematological parameters (MCV, MCH, MCHC, RDW, Hb, HCT) were recorded. Patients were monitored over 12 months for major adverse cardiovascular events, encompassing cardiovascular mortality, non-fatal myocardial infarction, non-fatal stroke, or cardiac rehospitalization. Statistical analysis was conducted using SPSS version 16, with significance defined as p < 0.05.
resultsAnemic patients had a higher prevalence of diabetes, hyperlipidemia, prior CABG, and smoking (all p < 0.05). They also exhibited significantly lower MCH, MCHC, Hb, and HCT, and higher RDW (p < 0.05). Correlation analyses revealed significant associations between various RBC indices and hematological parameters in both groups. However, in the multivariable analysis, none of the RBC indices including hemoglobin, hematocrit, MCH, and MCHC were independent predictors of rehospitalization or all-cause mortality (all p > 0.05). Hyperlipidemia showed a non-significant trend toward increased all-cause mortality (OR: 1.675; 95% CI: 0.954–2.942; p = 0.073).
conclusionAlthough anemia and aberrant red blood cell indices correlate with an unfavorable clinical profile in heart failure patients, they did not independently predict short-term major adverse cardiovascular events in this study population. This implies that the prognostic significance of these standard hematologic parameters may be constrained in advanced heart failure.
