Poor concordance of commonly used echocardiographic measures of left ventricular diastolic function in patients with suspected heart failure but preserved systolic function: is there a reliable echocardiographic measure of diastolic dysfunction?
Why the study?
Do different Doppler echocardiographic criteria for diastolic dysfunction show concordance in patients with suspected heart failure and preserved systolic function?
Population
Consecutive patients referred with suspected heart failure but preserved left ventricular systolic function.

Implication
Discordant echocardiographic criteria may limit diagnostic reliability in suspected HFpEF; leaves open the need for standardized definitions in research.
Structured PICO
Do different Doppler echocardiographic criteria for diastolic dysfunction show concordance in patients with suspected heart failure and preserved systolic function?
P
Population
Consecutive patients referred with suspected heart failure but preserved left ventricular systolic function.
I
Intervention
Doppler echocardiographic measurements of systolic and diastolic function evaluated against eight published age and sex specific reference ranges.
O
Outcome
Concordance of different Doppler echocardiographic criteria for diastolic dysfunction and proportion of patients outside normal limits.surrogate
Commonly used echocardiographic criteria for diastolic dysfunction show poor concordance, suggesting caution when diagnosing diastolic heart failure based on these measures.
