Chronic Heart Failure Questionnaire
Also known as: CHQ, Heart Failure Quality of Life, Chronic Heart Failure QoL
The CHQ is a disease-specific quality of life measure for chronic heart failure (CHF). Developed by Luc Guyonnet and colleagues in 2000, this 20-item questionnaire assesses how heart failure affects dyspnea, fatigue, emotional function, and activity limitation. It is used in heart failure clinical trials and research to quantify patient-experienced burden and treatment benefit.

When to use it
The CHQ is indicated for quality-of-life assessment in heart failure populations. Use cases include baseline assessment at diagnosis to establish functional burden and psychological impact, monitoring during guideline-directed medical therapy (ACE inhibitors, beta-blockers, aldosterone antagonists) and device therapy (pacemakers, defibrillators) to assess patient-experienced benefit, outcome measurement in heart failure trials as a secondary endpoint, research examining long-term natural history and psychosocial consequences, and prognostic assessment (low CHQ predicts hospitalizations and mortality). The CHQ is valuable in both systolic (reduced ejection fraction) and diastolic (preserved ejection fraction) heart failure. It is less suitable for acute decompensation (use symptom scales) or non-cardiac populations.
Strengths & limitations
- CHF-specific and multidimensional—developed from heart failure patient interviews, capturing dyspnea, fatigue, emotional burden, and activity limitation that generic QoL measures miss
- Brief and feasible—20 items, 5-10 minute completion, fits routine cardiology clinic visits
- Well-validated—used in major heart failure trials and cohort studies with demonstrated reliability (Cronbach's α 0.75-0.92 across domains) and responsiveness to therapies
- Prognostic value—low baseline CHQ predicts future hospitalizations and mortality, enabling risk stratification beyond ejection fraction alone
- Free and accessible—no licensing restrictions; published scoring algorithms widely available
- Does not measure objective cardiac function—CHQ reflects symptoms and quality of life, not ejection fraction or hemodynamics; echocardiography and biomarkers must be assessed separately
- Correlation with cardiac measures is modest—CHQ correlates weakly to moderately with ejection fraction, BNP, and NYHA class (r = 0.20-0.50); patients with similar cardiac severity may report vastly different CHQ due to coping, depression, and support
- Limited discriminant validity—cannot distinguish CHF from other causes of dyspnea (COPD, anemia, deconditioning); clinical assessment must confirm CHF diagnosis
- Potential response bias—patients may minimize symptoms if they fear hospitalization or medication escalation; depression and anxiety influence reported symptoms independent of cardiac function
- Multiple outcome measures exist—several other heart failure QoL instruments (Kansas City Cardiomyopathy Questionnaire, Minnesota Living with Heart Failure Questionnaire) complicate study comparisons
Frequently asked
A patient has CHF with EF 35% (reduced) but CHQ 5.5 (good). How is this possible?
Possible due to: (1) excellent medication optimization and adherence; (2) good exercise capacity despite low EF ('blue bloater' vs. 'pink puffer' phenotypes differ in symptom perception); (3) strong psychological coping and social support; (4) absence of comorbidities (anemia, atrial fibrillation, COPD) that amplify dyspnea. This patient is doing well functionally and psychologically; continue current therapy, monitor for decompensation, and encourage lifestyle modifications.
CHQ dropped from 4.5 to 3 (significant decline) in a stable CHF patient on same medications. What should I investigate?
Investigate: (1) medication non-adherence (diuretic, ACE-I, beta-blocker); (2) disease progression (recent hospitalizations? worsening dyspnea on exertion?); (3) new comorbidities (anemia, thyroid dysfunction, atrial fibrillation, sleep apnea); (4) depression (PHQ-9 screen); (5) social/psychosocial stressors (job loss, relationship conflict). Clinically assess (exam, BNP, EF if warranted) and intervene accordingly.
How does CHQ guide treatment intensity decisions?
CHQ is one input. A patient with CHQ 2 (severe impairment) on triple therapy (ACE-I, beta-blocker, diuretic) may benefit from: (1) aldosterone antagonist addition; (2) device evaluation (ICD if reduced EF, CRT if wide QRS); (3) heart transplant or mechanical support evaluation if advanced; (4) palliative care consultation if goals are comfort. Combine CHQ with objective measures (EF, BNP, exercise test, NYHA) for comprehensive decision-making.
Is CHQ appropriate for diastolic heart failure (HFpEF)?
CHQ applies to both systolic and diastolic heart failure, as dyspnea, fatigue, and activity limitation affect both. However, HFpEF patients often report lower absolute CHQ than systolic CHF with similar EF, possibly due to underdiagnosis, comorbidities (obesity, hypertension, atrial fibrillation), and physician focus on EF rather than symptoms. Use CHQ in HFpEF but compare to HFpEF-specific reference values when available.
