Insights
Diagnosing heart failure with preserved ejection fraction (HFpEF) is challenging. Key echocardiographic parameters like lateral E/e
Area of Science:
- Cardiology
- Medical Diagnostics
- Echocardiography
Background:
- Heart failure with preserved ejection fraction (HFpEF) lacks unified diagnostic criteria.
- Accurate diagnosis is crucial for effective patient management and treatment strategies.
Purpose of the Study:
- To evaluate current diagnostic criteria for HFpEF.
- To identify the most valuable echocardiographic parameters and diagnostic strategies for HFpEF.
Main Methods:
- Assessed echocardiographic data and N-terminal pro-brain natriuretic peptide levels in derivation (n=236) and validation (n=98) cohorts.
- Included normal controls, patients with hypertensive heart disease without heart failure, and patients with HFpEF.
- Evaluated single parameters and a brief diagnostic strategy.
Main Results:
- Lateral E/e' ratio (≥12), left atrial volume index (LAVI ≥34 mL/m(2)), and Ard-Ad difference (>30 ms) showed the highest diagnostic value as single parameters.
- A brief strategy using these parameters achieved 77% sensitivity and 81% specificity in the validation cohort.
Conclusions:
- Echocardiographic parameters lateral E/e', LAVI, and Ard-Ad are highly valuable for diagnosing HFpEF.
- A simple diagnostic strategy incorporating these parameters offers significant clinical utility for identifying diastolic dysfunction in HFpEF.
Aims:
There are no unified criteria for diagnosing heart failure with preserved ejection fraction (HFpEF). The aim of this study was to evaluate the present main diagnostic criteria and to discover which parameters and strategies are more valuable.
Methods And Results:
Echocardiographic data and plasma N-terminal pro-brain natriuretic peptide levels were assessed in a derivation cohort (n= 236) and a validation cohort (n= 98). Both cohorts included normal controls, patients with hypertensive heart disease without heart failure and patients with HFpEF. In the derivation cohort, the ratio of early mitral inflow velocity to tissue Doppler velocity at lateral mitral annulus (lateral E/e'≥12), left atrial volume index (LAVI≥34 mL/m(2)), and the difference between duration of reversed pulmonary vein atrial systole flow and duration of mitral A wave flow (Ard-Ad>30 ms) had the greatest diagnostic value among all the single parameters. A brief strategy that consisted of either: (i) lateral E/e'≥12; or (ii) 12>lateral E/e'≥8, with either LAVI≥34 mL/m(2) or Ard-Ad>30 ms, provided good diagnostic accuracy for identifying diastolic dysfunction in HFpEF, with a sensitivity of 77% and specificity of 81%. These observations were confirmed in the validation cohort.
Conclusion:
Echocardiographic parameters including lateral E/e', LAVI, and Ard-Ad have the greatest value in diagnosing HFpEF. A brief strategy that included these three parameters had great diagnostic value and would be simple to use in clinic practice.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
