Key result
Seven clinical questionnaires for heart failure diagnosis showed high specificity (usually >90%) but low sensitivity (55-84%), limiting their usefulness as standalone diagnostic instruments.
Why the study?
Do clinical questionnaires accurately diagnose chronic heart failure in primary care patients compared to ESC guidelines?
Cross-Sectional (n=5,434)
Yes
Do clinical questionnaires accurately diagnose chronic heart failure in primary care patients compared to ESC guidelines?
Clinical questionnaires for heart failure diagnosis in primary care have low sensitivity but high specificity, limiting their utility as primary diagnostic instruments but making them useful for identifying patients with symptoms from non-cardiac causes.

May aid ruling out HF in primary care; leaves open need for prospective validation and better tools versus ESC criteria.
Fonseca et al. (2004) conducted a cross-sectional in Chronic heart failure (n=5,434). Seven clinical questionnaires (Göteborg, Walma, Framingham, NHANES-I, Boston, Gheorghiade) vs. European Society of Cardiology (ESC) Guidelines was evaluated on Performance statistics (sensitivity and specificity) and concordance for the diagnosis of heart failure. Seven clinical questionnaires for heart failure diagnosis showed high specificity (usually >90%) but low sensitivity (55-84%), limiting their usefulness as standalone diagnostic instruments.
