Key result
A diagnostic rule combining six clinical variables and NT-proBNP accurately identified the presence of heart failure in geriatric outpatients (c-statistic 0.92).
Why the study?
Does a combination of clinical symptoms, signs, and NT-proBNP accurately diagnose heart failure in geriatric outpatients with suspected HF?
Population
206 geriatric outpatients with suspected heart failure, mean age 82 (±6) years, 30% men.
Design
Cross-sectional

Supports diagnostic rule evaluation in geriatric outpatients with suspected HF; leaves open prospective validation before clinical use.

Does a combination of clinical symptoms, signs, and NT-proBNP accurately diagnose heart failure in geriatric outpatients with suspected HF?
Effect estimate: c-statistic 0.92
A diagnostic rule combining six simple clinical variables and NT-proBNP can reliably identify or exclude heart failure in geriatric outpatients, potentially reducing the need for routine echocardiography.
Oudejans et al. (2011) conducted a cross-sectional in Suspected Heart Failure (n=206). Diagnostic rule (six clinical variables and NT-proBNP) was evaluated on Presence of heart failure (c-statistic 0.92). A diagnostic rule combining six clinical variables and NT-proBNP accurately identified the presence of heart failure in geriatric outpatients (c-statistic 0.92).
