Does anemia predict hospital readmission and mortality in older patients with HF?
Does anemia predict hospital readmission and mortality in older patients with HF?
Anemia in older heart failure patients is an independent predictor of hospital readmission but acts primarily as a marker of comorbid illness severity rather than a direct mediator of mortality.
Answers are grounded in this paper and cite their sources.
Anemia may flag readmission risk independently in older HF patients; leaves open whether correction improves mortality beyond comorbidity management.
Although anemia is an independent predictor of hospital readmission, its relationship with increased mortality in HF patients is largely explained by the severity of comorbid illness. These findings suggest that anemia may be predominantly a marker rather than a mediator of increased mortality risk in older patients with HF.
