Abstract

Abstract Background Anemia is a frequent comorbidity in patients with heart failure and is associated with increased morbidity, mortality, and reduced quality of life. However, data on anemia prevalence, associated factors, and its prognostic significance are limited in our region. This study aimed to determine the prevalence of anemia in outpatients with heart failure with reduced ejection fraction, identify contributing factors, and evaluate its impact on quality of life at the University of Gondar Comprehensive Specialized Hospital in Northwest Ethiopia. Methods An institution-based cross-sectional study was conducted using an interviewer-administered questionnaire. Data collected included demographic, lifestyle, clinical, biochemical, and echocardiographic characteristics. Health-related quality of life was assessed using the Minnesota Living with Heart Failure Questionnaire. Data were entered into EpiData 4.6 and analyzed using STATA 25. Bivariable and multivariable binary logistic regression analyses were performed to identify factors associated with anemia. Variables with a p-value ≤ 0.05 in the multivariable analysis (based on AORs with 95% CIs) were considered statistically significant. Results Among 226 participants (mean age 51.12 ± 13.17 years), the prevalence of anemia in heart failure with reduced ejection fraction patients was 44.2% (95% CI: 37.7–51.0). Anemia was significantly associated with Age ≥ 50 years: AOR 4.18 (95% CI: 1.65–10.58), Hypotension: AOR 3.96 (95% CI: 1.33–11.75), HF duration ≥ 1 year: AOR 4.60 (95% CI: 1.76–11.97), Recent hospitalization: AOR 3.31 (95% CI: 1.42–7.67), Presence of comorbidities: AOR 6.36 (95% CI: 2.28–17.76), Severely reduced ejection fraction: AOR 3.12 (95% CI: 1.29–7.52), and Poor quality of life: AOR 10.52 (95% CI: 3.9–28.36). Conclusion Anemia is highly prevalent among heart failure with reduced ejection fraction patients in this study and strongly associated with factors indicating advanced disease and comorbidity burden. Importantly, anemia is a significant predictor of poor Health-related quality of life. These findings highlight the need to recognize anemia as a key determinant of morbidity and reduced well-being in HFrEF patients.

Anemia quality of life heart failure reduced ejection fraction Ethiopia Figures Figure 1 Background Heart Failure (HF) is a complex and life-threatening condition that significantly impacts morbidity, mortality, functional ability, quality of life, and healthcare costs ( 1 ). As a global public health concern, it affects an estimated 64.3 million people worldwide, with roughly half of the cases classified as Heart Failure with Reduced Ejection Fraction (HFrEF)( 2 , 3 ). In Sub-Saharan Africa, HF remains a major health challenge and is among the top five leading causes of death in Ethiopia( 4 ). Anemia is a frequent comorbidity in heart failure patients, particularly those with HFrEF, with studies suggesting that over one-third of HFrEF patients are affected. The reported prevalence of anaemia in this population varies significantly depending on factors such as patient demographics, the diagnostic criteria used, HF severity, and the presence of additional comorbidities ( 5 – 9 ). Notably, prevalence can reach up to 50% in hospitalized patients with acute heart failure decompensation ( 10 ). The development of anaemia in HF patients stems from a complex interplay of factors, including chronic kidney disease (CKD), diabetes mellitus (DM), hypertension, micronutrient deficiencies, and conditions causing blood loss ( 5 , 11 ). The predominant form is anaemia of chronic disease, driven by renal dysfunction, impaired erythropoiesis, reduced erythropoietin (EPO) responsiveness, and systemic inflammation. Additionally, plasma volume expansion and hemodilution may contribute to pseudoanaemia. Certain medications, such as angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), have also been associated with anaemia due to their suppression of EPO synthesis and bone marrow activity. While deficiencies in iron, folate, and vitamin B12 play a role, iron deficiency accounts for a significant proportion of cases ( 5 , 9 , 11 , 12 ). Independent risk factors for anaemia in HF include male sex, advanced age, higher NYHA functional class, lower systolic blood pressure, CKD, diabetes, ischemic aetiology, and the use of diuretics and ACEIs/ARBs ( 13 – 15 ). Anaemia in HF is associated with increased hospitalization rates, higher morbidity and mortality, and diminished quality of life (QoL) ( 8 , 16 ). The correlation between anemia and QoL can be attributed to several factors. Anemia often leads to increased fatigue, decreased exercise tolerance, and greater difficulty in performing daily activities, thereby negatively impacting the health-related QoL. Additionally, the presence of anemia has been associated with increased symptoms of depression and anxiety in patients with HF, further deteriorating QoL. Early treatment of anemia may therefore enhance both clinical outcomes and overall patient QoL ( 11 , 15 ). Despite its clinical significance, there is limited research on anaemia in HF patients within our region. This study aims to assess the prevalence of anaemia, identify associated factors, and evaluate its impact on quality of life among HFrEF patients at the University of Gondar Comprehensive Specialized Hospital in Northwest Ethiopia. Methods and materials Study design, setting, and population The study was a cross-sectional, institution-based study conducted from August 2023 to January 2024 at the University of Gondar Comprehensive Specialized Hospital (UoGCSH) in North West Ethiopia. This facility ranks among the largest hospitals in the country, offering health services to approximately 13 million individuals within its catchment area. UoGCSH features several follow-up clinics dedicated to major chronic illnesses, one of which is the Cardiac clinic. Currently, around 3,000 cardiac patients receive ongoing care at this specialized clinic. The source population comprised all adult patients diagnosed with HFrEF who were under chronic follow-up at the UoGCSH. The study population included all adult patients with HFrEF who attended the chronic follow-up clinic at UoGCSH throughout the defined study period. Inclusion and exclusion criteria Adult patients aged 18 years and older diagnosed with HFrEF who had received follow-up care at the cardiac clinic of the UoGCSH for a minimum duration of three months were included in this study. Exclusion criteria comprised Patients with cognitive impairments (e.g., dementia, psychosis) affecting recall ability. Those with acute concurrent conditions (e.g., acute heart failure exacerbations, severe infections) that could substantially alter quality of life. Pregnant women and patients receiving iron supplementation or blood transfusions. Sample size and sampling procedure The sample size was calculated using Epi Info, based on an 82% prevalence from a prior study in Nepal (17), a 95% confidence interval, and a 5% marginal error. Adding a 10% non-response rate, the total sample size was 232. A consecutive sampling technique was utilized, enrolling all eligible patients until the target sample size was reached. Data collection tools and procedures Data were collected using structured questionnaires, covering: Sociodemographic, lifestyle, clinical, biochemical, and echocardiographic variables. Health-Related Quality of Life (HRQoL), assessed via the Minnesota Living with Heart Failure Questionnaire (MLHFQ)—a globally validated tool for HF patients (18, 19). The MLHFQ was translated into Amharic (local language) and back-translated to English to ensure consistency. Clinical, biochemical, and echocardiographic data were extracted from medical records. For lab parameters (hemoglobin, serum creatinine, serum sodium), three-month averages prior to the visit were used. Analyses were performed using Yumizen H550 (hematology) and AU480 (chemistry) automated analyzers. Sociodemographic and MLHFQ data were obtained through face-to-face interviews conducted by two trained cardiac nurses, supervised by a general practitioner. Data quality assurance Training: Data collectors and supervisors received instruction on protocols, study objectives, and confidentiality. Pretesting: A pilot test with 20 participants evaluated questionnaire clarity, language appropriateness, and reliability. Daily monitoring: The principal investigator and supervisor reviewed data for accuracy and completeness throughout the collection phase. This study shared methodological similarities with a prior study conducted in the same setting (20), particularly in terms of design, duration, study population, and data collection tools and procedures. However, it differed in its inclusion/exclusion criteria and had distinct study objectives. Study variables Dependent variable Anemia Independent variables Demographic Factors: Age, gender, place of residence, marital status, educational attainment, occupation, and income level. Lifestyle Factors: Current smoking habits, alcohol consumption, and dietary salt intake. Clinical Factors: Vital signs: Systolic blood pressure (SBP), heart rate (HR). HF characteristics: Duration of HF, etiology (ischemic heart disease [IHD], dilated cardiomyopathy [DCMP], chronic rheumatic valve disease [CRVHD], degenerative valvular heart disease [DVHD], others). Disease severity: NYHA functional class (I–IV), recent hospitalization (past 6 months). Comorbidities: Atrial fibrillation, hypertension, obesity, dyslipidemia, diabetes mellitus (DM), chronic kidney disease (CKD), etc. Medications: Diuretics, beta-blockers, ACEIs/ARBs, spironolactone, digoxin, antiplatelets, anticoagulants, statins, etc. Biochemical Factors: Hemoglobin, Serum creatinine, Serum sodium (averaged from results obtained over the past three months). Echocardiographic Factors: Left ventricular ejection fraction (LVEF) and pulmonary hypertension (PH) severity at HF diagnosis. Health related quality of life: assessed by Minnesota Living with Heart Failure Questionnaire. Operational definitions Anemia Anemia was defined according to World Health Organization (WHO) criteria as hemoglobin levels below 12 g/dL for non-pregnant women and below 13 g/dL for men. The WHO further classifies anemia severity as follows. In men: Mild anemia (11–12.9 g/dL), Moderate anemia (8–10.9 g/dL) and Severe anemia (< 8 g/dL). In non-pregnant women: Mild anemia (11–11.9 g/dL), Moderate anemia (8–10.9 g/dL) and Severe anemia (< 8 g/dL)(21). Heart failure with reduced ejection fraction patients Defined as HF patients with an echocardiographically confirmed LVEF ≤40%. Health-related quality of life Health-related quality of life in patients with HF is an important patient-reported health status measure that evaluates the impact of HF and its medical interventions on various domains of life. It is evaluated using the MLHFQ, which consists of 21 items rated on a 6-point Likert scale (0 = no impact, 5 = severe impact). Total score range: 0–105 (higher scores indicate worse HRQoL). Subscales: Physical domain (items 2–7, 12–13; range 0–40), Emotional domain (items 17–21; range 0–25). Classification: Good HRQoL: 45 (22). New York Heart Association (NYHA) Functional Class Class I: No limitations in physical activity. Class II: Mild limitations (comfortable at rest, but ordinary activity causes symptoms). Class III: Marked limitations (comfortable at rest, but minimal activity triggers symptoms). Class IV: Symptoms at rest; inability to perform any physical activity without discomfort (23). Data processing and analysis The collected data were entered into Epi Data version 4.6 and analyzed using SPSS version 25 after verifying data integrity. A reliability test (Cronbach’s alpha) was performed to assess the consistency of the items in the MLHFQ tool, yielding values of 0.99 for overall HRQoL, 0.98 for the physical domain, and 0.98 for the emotional domain. Descriptive analyses, including frequencies, means, and medians, were conducted. To identify factors associated with anemia, both bivariable and multivariable logistic regression analyses were employed. Variables with p-values <0.25 in the bivariable analysis were included in the multivariable model, and those with p-values ≤0.05 were considered statistically significant. Model fitness was evaluated using the Hosmer-Lemeshow test, which yielded a p-value of 0.4 (>0.05), indicating a good fit. The findings were systematically organized and presented using frequency tables and graphs. Results Demographic and lifestyle characteristics The study included 226 patients with HFrEF under follow-up at a cardiac clinic, achieving a response rate of 97.4%. The majority (52.2%) were over 50 years old, with a mean age of 51.12 ± 13.17 years. Among the participants, 51.3% were female, 50.4% resided in urban areas, and 60.6% were married. Nearly one-third (33.6%) were housewives, while 41.6% had no formal education. Regarding lifestyle factors, 9.7% were current smokers, 33.2% reported high salt intake, and 20.4% were current alcohol drinkers (Table 1). Clinical, biochemical and echocardiographic Characteristics The study participants had a median (IQR) SBP of 105 (20) mmHg (range: 75–150), with 27.4% experiencing hypotension. The median (IQR) HR was 89 (23) bpm (range: 40–112), and 35.8% of patients had tachycardia. The median (IQR) illness duration was 1.5 (1.0) years (range: 6 months–6 years), with 78.3% of patients having HF for over a year. Most participants (53.1%) were classified as NYHA class III or IV, and 45.1% had been hospitalized within the past six months. The primary etiologies of HFrEF identified were IHD (39.8%), CRVHD (24.8%), DCMP (24.3%), and DVHD (11.1%). Among the participants, 58.4% had at least one comorbidity; including atrial fibrillation (24.3%), hypertension (23.5%), dyslipidemia (18.6%), diabetes (11.1%), thyrotoxicosis (9.3%), and obesity (8.8%). Medication use was as follows: ACEIs/ARBs (92%), beta-blockers (76.1%), furosemide (60.6%), antiplatelets (40.7%), statins (36.7%), spironolactone (32.3%), anticoagulants (24.8%), and digoxin (2.7%) (Table 2). This study included the mean values of laboratory results obtained over the past three months. The median (IQR) values were as follows: Hemoglobin (Hg): 13.5 (3.8) g/dL (range: 7–16.9 g/dL), with 34.2% of patients exhibiting low Hg levels. Creatinine (Cr): 0.99 (0.83) mg/dL (range: 0.45–3.3 mg/dL), with 39.8% of patients having elevated Cr. Sodium (Na): 137 (8) mEq/L (range: 120–150 mEq/L), with 35.8% of patients having hyponatremia. Regarding cardiac function: on baseline echocardiography, LVEF was a median (IQR) of 30 (7.25)% (range: 14–40%), with 36.7% of patients having severe systolic dysfunction and 63.3% exhibiting moderate systolic dysfunction. 62.4% had mild or no PH, while 37.6% had moderate or severe PH. (Table 3). Prevalence of Anemia and its impact on Quality of Life Study participants’ chart review was conducted to evaluate the prevalence of anemia among HFrEF patients. Out of 226 HFrEF patients on follow-up at UoGCSH, 100 (44.2%) were found to have anemia. This study confirms an overall anemia prevalence of 44.2% (95% CI: 37.7–51.0) in this patient population. Among anemic HFrEF patients, 45 (45%) of patients had mild anemia, 43 (43%) had moderate anemia and 12 (12%) of patients had severe anemia. In this study, the MLHFQ was used to evaluate HRQoL, revealing mean scores of 17.69 ± 10.46 for physical domain, 10.70 ± 6.34 for emotional domain, and 47.36 ± 47 for total HRQoL. 43.8% of participants were classified as having a poor HRQoL, while 24.8% and 31.4% were assessed as having moderate and good HRQoL, respectively (Table 4). Among anemic HFrEF patients, 82 (82%) of patients had poor HRQoL while 8 (8%) had moderate HRQoL and 10(10%) patients had good HRQoL (Fig 1). Factors associated with Anemia In the Bivariable logistic regression: patient age, sex, smoking and alcohol history, salt intake, SBP, HR, duration of HF, NYHA class, recent hospitalization, comorbidities (hypertension, diabetes mellitus, atrial fibrillation, thyrotoxicosis, dyslipidemia), HF medications (β-blockers, furosemide, antiplatelets, anticoagulants), serum creatinine and sodium levels, baseline echocardiography LVEF, and HRQoL were included as candidate variables for multivariable logistic regression analysis at a significance level of 0.25. In multivariable logistic regression analysis, seven significant predictors of anemia in HFrEF patients were identified. Age ≥50 years: AOR 4.18 (95% CI: 1.65–10.58), Hypotension (SBP<90 mmHg): AOR 3.96 (95% CI: 1.33–11.75), HF duration ≥1 year: AOR 4.60 (95% CI: 1.76–11.97), Recent hospitalization: AOR 3.31 (95% CI: 1.42–7.67), Presence of comorbidities: AOR 6.36 (95% CI: 2.28–17.76), Severely reduced LVEF: AOR 3.12 (95% CI: 1.29–7.52), and Poor HRQoL: AOR 10.52 (95% CI: 3.9–28.36) (Table 5). Discussion This study provides important insights into the burden of anemia, its contributing factors, and its profound impact on the well-being of HFrEF patients. The findings highlight anemia as a highly prevalent and clinically significant comorbidity in this population, intricately linked to both disease severity and patient-reported outcomes. The observed anemia prevalence of 44.2% (95% CI: 37.7–51.0) among HFrEF patients in this study underscores its substantial burden. This rate was comparable to that of general HF patients at Brazzaville University Hospital, Congo (42%)( 24 ) and to Asian patients with HFrEF (41%) ( 15 ). However, our finding is higher than the prevalence of 27% reported in a study from Saudi Arabia and significantly lower than the 82% reported in Nepal ( 17 ). This large variability may be explained by demographic and methodological differences. This elevated prevalence likely reflects a confluence of factors prevalent in this population and setting, including nutritional deficiencies (iron, folate, vitamin B12), a high burden of chronic infections/inflammation (e.g., malaria, helminths, tuberculosis), CKD often associated with HF, and potentially limited access to optimal HF management and anemia diagnostics/treatment prior to presentation. The finding reinforces that anemia is not merely a bystander but a major comorbidity demanding attention in HFrEF care ( 7 , 8 ). The current study identified factors associated with anemia among HFrEF patients. The odds of developing anemia in HFrEF patients aged ≥ 50 years were 4.18 times higher, a finding consistent with previous studies in Asian ( 15 ) and Swedish populations ( 25 ). This strong association aligns with physiological aging processes, including reduced erythropoietin responsiveness, a higher prevalence of comorbidities contributing to anemia (e.g., CKD, occult malignancies), and potential nutritional deficiencies. It underscores the need for heightened vigilance for anemia in older HFrEF patients ( 11 ). In this study, hypotensive HFrEF patients had 3.96 times higher odds of anemia compared to normotensive patients, consistent with studies from Nigeria ( 26 ) and Sweden ( 27 ). Low systolic blood pressure often reflects advanced HF, reduced cardiac output, and consequently, impaired renal perfusion. This can suppress erythropoietin production, directly linking hemodynamic compromise to anemia development ( 5 ). HFrEF patients with a disease duration of ≥ 1 year had 4.6 times higher odds of anemia than those with shorter durations. Longer disease duration signifies greater cumulative exposure to the pathophysiological mechanisms linking HF and anemia, including chronic inflammation, neurohormonal activation (e.g., RAAS overactivity), renal dysfunction, and potentially the effects of long-term loop diuretic use (e.g., iron loss)( 5 , 11 ). HFrEF patients with a recent hospitalization history had 3.31 times higher odds of anemia, mirroring findings in Swedish studies ( 25 ). Hospitalization is a marker of HF instability, disease severity, and acute decompensation. These states exacerbate inflammation, hemodynamic compromise affecting renal function, and nutritional deficiencies, all contributing to or worsening anemia. Anemia itself can also precipitate hospitalization, suggesting a potential bidirectional relationship( 11 ). The prevalence of anemia among HFrEF patients with comorbidities was 6.36 times higher, aligning with studies from Thailand ( 28 ) and Sweden ( 25 ). Comorbidities like CKD (impairing erythropoietin production and iron metabolism), diabetes (associated with anemia of chronic disease and CKD), chronic inflammatory conditions, and occult blood loss significantly amplify anemia risk ( 11 , 29 , 30 ). HFrEF patients with severely reduced LVEF had 3.12 times higher odds of anemia than those with moderate LVEF, consistent with Nigerian data ( 26 ). More severe systolic dysfunction correlates with worse cardiac output, lower renal perfusion, greater neurohormonal activation, and higher levels of inflammatory cytokines, all established pathways contributing to anemia in HF. This links the core pathophysiology of HFrEF directly to anemia risk ( 5 , 11 , 31 ). Finally, anemia prevalence was 10.52 times higher in HFrEF patients with poor HRQoL, matching findings from Nigeria ( 26 ), Iran ( 32 ), Asia ( 15 ). This suggests a profound link between anemia and diminished quality of life. Anemia likely exacerbates fatigue, dyspnea, and exercise intolerance, impairing daily functioning, while poor HRQoL may reflect or worsen HF and anemia severity ( 33 – 35 ). Strengths of the study include its focus on a clinically important comorbidity in an understudied population, the use of adjusted analyses to identify independent predictors, and the inclusion of patient-centered HRQoL outcomes. Limitations include the single-center design, which may limit generalizability; the cross-sectional nature of the study, preventing causal inference; possible residual confounding due to unmeasured variables (e.g., detailed nutritional status, specific comorbidities, medication adherence); and the lack of data on anemia subtypes (e.g., iron deficiency). Conclusion Anemia is highly prevalent (44.2%) among HFrEF patients and is strongly associated with factors indicative of advanced disease and comorbidity burden (older age, hypotension, longer HF duration, recent hospitalization, comorbidities, severely reduced LVEF). Crucially, anemia is independently and very strongly associated with poor Health-Related Quality of Life, affecting the vast majority of anemic patients. These findings underscore the critical importance of recognizing anemia as a key determinant of morbidity and impaired well-being in HFrEF patients. Integrating routine anemia screening, etiological investigation, and management into standard HF care protocols, particularly for high-risk individuals, holds significant potential to alleviate symptoms, improve functional capacity and quality of life, and potentially modify the disease trajectory in this vulnerable population. Future research should focus on longitudinal outcomes and targeted interventions for anemia in this setting.

As a global public health concern, it affects an estimated 64.3\u0026nbsp;million people worldwide, with roughly half of the cases classified as Heart Failure with Reduced Ejection Fraction (HFrEF)(\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e, \u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e). In Sub-Saharan Africa, HF remains a major health challenge and is among the top five leading causes of death in Ethiopia(\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eAnemia is a frequent comorbidity in heart failure patients, particularly those with HFrEF, with studies suggesting that over one-third of HFrEF patients are affected. The reported prevalence of anaemia in this population varies significantly depending on factors such as patient demographics, the diagnostic criteria used, HF severity, and the presence of additional comorbidities (\u003cspan additionalcitationids=\"CR6 CR7 CR8\" citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e). Notably, prevalence can reach up to 50% in hospitalized patients with acute heart failure decompensation (\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eThe development of anaemia in HF patients stems from a complex interplay of factors, including chronic kidney disease (CKD), diabetes mellitus (DM), hypertension, micronutrient deficiencies, and conditions causing blood loss (\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e, \u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e). The predominant form is anaemia of chronic disease, driven by renal dysfunction, impaired erythropoiesis, reduced erythropoietin (EPO) responsiveness, and systemic inflammation. Additionally, plasma volume expansion and hemodilution may contribute to pseudoanaemia. Certain medications, such as angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), have also been associated with anaemia due to their suppression of EPO synthesis and bone marrow activity. While deficiencies in iron, folate, and vitamin B12 play a role, iron deficiency accounts for a significant proportion of cases (\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e, \u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e, \u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e, \u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e).

The correlation between anemia and QoL can be attributed to several factors. Anemia often leads to increased fatigue, decreased exercise tolerance, and greater difficulty in performing daily activities, thereby negatively impacting the health-related QoL. Additionally, the presence of anemia has been associated with increased symptoms of depression and anxiety in patients with HF, further deteriorating QoL. Early treatment of anemia may therefore enhance both clinical outcomes and overall patient QoL (\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e, \u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eDespite its clinical significance, there is limited research on anaemia in HF patients within our region.

This can suppress erythropoietin production, directly linking hemodynamic compromise to anemia development (\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eHFrEF patients with a disease duration of \u0026ge;\u0026thinsp;1 year had 4.6 times higher odds of anemia than those with shorter durations. Longer disease duration signifies greater cumulative exposure to the pathophysiological mechanisms linking HF and anemia, including chronic inflammation, neurohormonal activation (e.g., RAAS overactivity), renal dysfunction, and potentially the effects of long-term loop diuretic use (e.g., iron loss)(\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e, \u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eHFrEF patients with a recent hospitalization history had 3.31 times higher odds of anemia, mirroring findings in Swedish studies (\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e). Hospitalization is a marker of HF instability, disease severity, and acute decompensation. These states exacerbate inflammation, hemodynamic compromise affecting renal function, and nutritional deficiencies, all contributing to or worsening anemia. Anemia itself can also precipitate hospitalization, suggesting a potential bidirectional relationship(\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eThe prevalence of anemia among HFrEF patients with comorbidities was 6.36 times higher, aligning with studies from Thailand (\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e) and Sweden (\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e). Comorbidities like CKD (impairing erythropoietin production and iron metabolism), diabetes (associated with anemia of chronic disease and CKD), chronic inflammatory conditions, and occult blood loss significantly amplify anemia risk (\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e, \u003cspan citationid=\"CR29\" class=\"CitationRef\"\u003e29\u003c/span\u003e, \u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e30\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eHFrEF patients with severely reduced LVEF had 3.12 times higher odds of anemia than those with moderate LVEF, consistent with Nigerian data (\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e). More severe systolic dysfunction correlates with worse cardiac output, lower renal perfusion, greater neurohormonal activation, and higher levels of inflammatory cytokines, all established pathways contributing to anemia in HF. This links the core pathophysiology of HFrEF directly to anemia risk (\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e, \u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e, \u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eFinally, anemia prevalence was 10.52 times higher in HFrEF patients with poor HRQoL, matching findings from Nigeria (\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e), Iran (\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e), Asia (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e). This suggests a profound link between anemia and diminished quality of life. Anemia likely exacerbates fatigue, dyspnea, and exercise intolerance, impairing daily functioning, while poor HRQoL may reflect or worsen HF and anemia severity (\u003cspan additionalcitationids=\"CR34\" citationid=\"CR33\" class=\"CitationRef\"\u003e33\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR35\" class=\"CitationRef\"\u003e35\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eStrengths of the study include its focus on a clinically important comorbidity in an understudied population, the use of adjusted analyses to identify independent predictors, and the inclusion of patient-centered HRQoL outcomes.\u003c/p\u003e \u003cp\u003eLimitations include the single-center design, which may limit generalizability; the cross-sectional nature of the study, preventing causal inference; possible residual confounding due to unmeasured variables (e.g., detailed nutritional status, specific comorbidities, medication adherence); and the lack of data on anemia subtypes (e.g., iron deficiency).\u003c/p\u003e"},{"header":"Conclusion","content":"\u003cp\u003eAnemia is highly prevalent (44.2%) among HFrEF patients and is strongly associated with factors indicative of advanced disease and comorbidity burden (older age, hypotension, longer HF duration, recent hospitalization, comorbidities, severely reduced LVEF). Crucially, anemia is independently and very strongly associated with poor Health-Related Quality of Life, affecting the vast majority of anemic patients. These findings underscore the critical importance of recognizing anemia as a key determinant of morbidity and impaired well-being in HFrEF patients. Integrating routine anemia screening, etiological investigation, and management into standard HF care protocols, particularly for high-risk individuals, holds significant potential to alleviate symptoms, improve functional capacity and quality of life, and potentially modify the disease trajectory in this vulnerable population. Future research should focus on longitudinal outcomes and targeted interventions for anemia in this setting.\u003c/p\u003e"},{"header":"Abbreviations","content":"\u003cp\u003eACEI, Angiotensin converting enzyme inhibitor; ARB, Angiotensin receptor blocker; bbp, beat per minutes; CRVHD, Chronic rheumatic valvular heart disease; CKD, Chronic kidney disease; DCMP, Dilated cardiomyopathy; DM, Diabetes mellitus; DVHD, Degenerative valve heart disease; EPO, Erythropoietin; Hb, Hemoglobin; HF, Heart failure; HFrEF, Heart failure with reduced ejection fraction; HRQoL, Health-Related Quality of Life; HR, Heart rate; IHD, Ischemic heart disease; LVEF, Left ventricular ejection fraction; MLHFQ, Minnesota Living with Heart Failure Questionnaire ; mmHg, Millimetres of mercury, NYHA, New York Heart Association; Pulmonary hypertension, PH; QoL, Quality of life; RAAS, Renin angiotensin aldosterone system; SBP, Systolic blood pressure; UoGCSH, University of Gondar Comprehensive Specialized Hospital\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eEthics approval and consent to participate\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThis study received ethical approval from the Ethical Review Board of the School of Medicine, College of Medicine and Health Sciences, University of Gondar (Reference No.: SOM/06/01659/2015; Approval Date: May 18, 2023).\u0026nbsp;Written informed consent was obtained from all participants prior to their inclusion in the study.

and is associated with increased morbidity, mortality, and reduced quality of life. However, data on anemia prevalence, associated factors, and its prognostic significance are limited in our region. This study aimed to determine the prevalence of anemia in outpatients with heart failure with reduced ejection fraction, identify contributing factors, and evaluate its impact on quality of life at the University of Gondar Comprehensive Specialized Hospital in Northwest Ethiopia.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e \u003cp\u003eAn institution-based cross-sectional study was conducted using an interviewer-administered questionnaire. Data collected included demographic, lifestyle, clinical, biochemical, and echocardiographic characteristics. Health-related quality of life was assessed using the Minnesota Living with Heart Failure Questionnaire. Data were entered into EpiData 4.6 and analyzed using STATA 25. Bivariable and multivariable binary logistic regression analyses were performed to identify factors associated with anemia. Variables with a p-value\u0026thinsp;\u0026le;\u0026thinsp;0.05 in the multivariable analysis (based on AORs with 95% CIs) were considered statistically significant.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eAmong 226 participants (mean age 51.12\u0026thinsp;\u0026plusmn;\u0026thinsp;13.17 years), the prevalence of anemia in heart failure with reduced ejection fraction patients was 44.2% (95% CI: 37.7\u0026ndash;51.0). Anemia was significantly associated with Age\u0026thinsp;\u0026ge;\u0026thinsp;50 years: AOR 4.18 (95% CI: 1.65\u0026ndash;10.58), Hypotension: AOR 3.96 (95% CI: 1.33\u0026ndash;11.75), HF duration\u0026thinsp;\u0026ge;\u0026thinsp;1 year: AOR 4.60 (95% CI: 1.76\u0026ndash;11.97), Recent hospitalization: AOR 3.31 (95% CI: 1.42\u0026ndash;7.67), Presence of comorbidities: AOR 6.36 (95% CI: 2.28\u0026ndash;17.76), Severely reduced ejection fraction: AOR 3.12 (95% CI: 1.29\u0026ndash;7.52), and Poor quality of life: AOR 10.52 (95% CI: 3.9\u0026ndash;28.36).\u003c/p\u003e\u003ch2\u003eConclusion\u003c/h2\u003e \u003cp\u003eAnemia is highly prevalent among heart failure with reduced ejection fraction patients in this study and strongly associated with factors indicating advanced disease and comorbidity burden. Importantly, anemia is a significant predictor of poor Health-related quality of life.
