Key result
In patients hospitalized with acute heart failure, the combined presence of anemia and hypoalbuminemia was not significantly associated with increased in-hospital mortality compared with having neither abnormality (OR 0.909).
Why the study?
Hematologic and nutritional abnormalities such as anemia and hypoalbuminemia are common in acute heart failure patients and may be associated with adverse outcomes, but their combined prognostic impact is unclear.
Do combined anemia and hypoalbuminemia phenotypes predict in-hospital mortality in patients hospitalized with acute heart failure?
Observational (n=220)

Odds Ratio: 0.909 (95% CI 0.224–3.689)
Absolute Event Rate: 7.8% vs 7.7%
p-value: p=0.894
Combined anemia and hypoalbuminemia phenotypes did not demonstrate independent prognostic value for short-term in-hospital mortality in this cohort of patients with acute heart failure.
Does not support anemia-hypoalbuminemia phenotyping for in-hospital mortality prediction in acute HF; leaves open need for prospective confirmation.
Objective: Hematologic and nutritional abnormalities are common in patients hospitalized with acute heart failure and may be associated with adverse outcomes.This study aimed to evaluate the clinical characteristics and in-hospital mortality of patients classified according to combined anemia and hypoalbuminemia phenotypes.Method: This retrospective study included 220 consecutive patients hospitalized with acute heart failure.Anemia was defined according to World Health Organization sex-specific hemoglobin thresholds, and hypoalbuminemia was defined as a serum albumin level <3.5 g/ dL.Patients were classified into four phenotypes: Neither anemia nor hypoalbuminemia, anemia alone, hypoalbuminemia alone, and both anemia and hypoalbuminemia.Associations between phenotype groups and all-cause in-hospital mortality were evaluated using categorical comparisons and logistic regression.Given the limited number of mortality events, a parsimonious age-adjusted model and bootstrap sensitivity analysis were performed.Results: Among 220 patients, 21 (9.5%) died during hospitalization.The four phenotype groups comprised 39 patients with neither abnormality, 34 with anemia alone, 45 with hypoalbuminemia alone, and 102 with both abnormalities.In-hospital mortality rates were 7.7%, 17.6%, 8.9%, and 7.8%, respectively, with no significant overall difference among groups (Fisher's exact p=0.402).In the age-adjusted logistic regression model, phenotype group was not significantly Öz Amaç: Akut kalp yetersizliği nedeniyle hastaneye yatırılan hastalarda hematolojik ve nütrisyonel bozukluklar sık görülmekte olup olumsuz klinik sonuçlarla ilişkili olabilir.Bu çalışmada, kombine anemihipoalbüminemi fenotiplerine göre sınıflandırılan hastaların klinik özelliklerinin ve hastane içi mortalitelerinin değerlendirilmesi amaçlandı.Yöntem: Bu retrospektif çalışmaya akut kalp yetersizliği nedeniyle hastaneye yatırılan 220 ardışık hasta dahil edildi.Anemi, Dünya Sağlık Örgütü'nün cinsiyete özgü hemoglobin eşik değerlerine göre; hipoalbüminemi ise serum albümin düzeyinin <3,5 g/dL olması olarak tanımlandı.Hastalar anemi ve hipoalbüminemi bulunmayanlar, yalnızca anemisi olanlar, yalnızca hipoalbüminemisi olanlar ve hem anemi hem de hipoalbüminemisi olanlar olmak üzere dört fenotipe ayrıldı.Fenotip grupları ile tüm nedenlere bağlı hastane içi mortalite arasındaki ilişkiler kategorik karşılaştırmalar ve lojistik regresyon analizleriyle değerlendirildi.Mortalitenin sınırlı sayıda olması nedeniyle parsimoniyöz, yaşa göre düzeltilmiş bir model ve bootstrap duyarlılık analizi uygulandı.Bulgular: Toplam 220 hastanın 21'i (%9,5) hastanede yatış sırasında yaşamını yitirdi.Anemi ve hipoalbüminemisi olmayan grupta 39, yalnızca anemisi olan grupta 34, yalnızca hipoalbüminemisi olan grupta 45 ve her iki bozukluğun birlikte bulunduğu grupta 102 hasta vardı.

Arın et al. (2026) conducted an observational in Acute heart failure (n=220). Combined anemia and hypoalbuminemia vs. Neither anemia nor hypoalbuminemia was evaluated on All-cause in-hospital mortality (OR 0.909, 95% CI 0.224-3.689, p=0.894). In patients hospitalized with acute heart failure, the combined presence of anemia and hypoalbuminemia was not significantly associated with increased in-hospital mortality compared with having neither abnormality (OR 0.909).
