Role of Diastolic Stress Testing in the Evaluation for Heart Failure With Preserved Ejection Fraction
Why the study?
Does adding exercise echocardiography to resting data improve the diagnostic accuracy for HFpEF in patients with dyspnea?
Population
Subjects with invasively proven HFpEF and participants with dyspnea but no identifiable cardiac pathology
Comparison
Simultaneous echocardiographic-catheterization… vs Resting echocardiographic data alone

Implication
Adding exercise echocardiography to resting data significantly improves the sensitivity for diagnosing HFpEF, suggesting resting data alone is insufficient to rule out the condition.
Structured PICO
Does adding exercise echocardiography to resting data improve the diagnostic accuracy for HFpEF in patients with dyspnea?
P
Population
Subjects with invasively proven HFpEF (n=50) and participants with dyspnea but no identifiable cardiac pathology (n=24)
I
Intervention
Simultaneous echocardiographic-catheterization studies at rest and during exercise (addition of exercise E/e' ratio >14)
C
Comparator
Resting echocardiographic data alone (current guidelines)
O
Outcome
Diagnostic accuracy (sensitivity, specificity, negative predictive value) for HFpEFsurrogate
Adding exercise echocardiography to resting data significantly improves the sensitivity for diagnosing HFpEF, suggesting resting data alone is insufficient to rule out the condition.
