Pulsatile Hemodynamics in Patients With Exertional Dyspnea

Q: What are the key findings of this study?

Adding measures of pulsatile arterial hemodynamics to tissue Doppler echocardiography improved the diagnosis of HFPEF, with a net reclassification improvement of 32.9% (p<0.0001).

Q: What is the clinical evidence from this study?

Study design: Observational. Population: Heart failure with preserved ejection fraction (HFPEF) (n=359). Intervention: Measures of pulsatile arterial function vs. Tissue Doppler echocardiography (TDE). Primary outcome: Separation of HFPEF from no HFPEF (Net reclassification improvement 32.9%, p=<0.0001).

Key result

Adding pulsatile arterial hemodynamics to tissue Doppler echocardiography improves HFpEF diagnosis by ~33%.

Net reclassification improvement 32.9%
P<0.0001
n=359

Why the study?

Increased arterial stiffness and wave reflections are present in most patients with HFPEF, but whether measures of pulsatile arterial function are useful for diagnosing HFPEF compared with and added to TDE was unknown.

Do measures of pulsatile arterial hemodynamics improve the diagnostic accuracy for HFPEF when added to tissue Doppler echocardiography in patients with exertional dyspnea?

Key Points

This research aims to determine the utility of pulsatile arterial function measures in diagnosing heart failure with preserved ejection fraction (HFPEF).
Patients with exertional dyspnea were classified as having HFPEF or no HFPEF based on filling pressures and natriuretic peptide levels.
Pulsatile arterial parameters such as pulse wave velocity (PWV) and aortic pulse pressure (aoPP) were measured invasively and noninvasively.
Receiver-operating curve analysis was conducted to assess diagnostic accuracy.
Patients with HFPEF had higher measures of arterial stiffness, with AUC for aortic PWV at 0.867 and aoPP at 0.825.
Combining pulsatile function measures with TDE increased AUC to 0.875 for bPP and 0.901 for aoPP.
Net reclassification improvement of 32.9% was noted when adding pulsatile measures to TDE (p < 0.0001).

Structured PICO

Do measures of pulsatile arterial hemodynamics improve the diagnostic accuracy for HFPEF when added to tissue Doppler echocardiography in patients with exertional dyspnea?

Population

359 patients with exertional dyspnea, categorized into HFPEF, no HFPEF, or intermediate based on invasive filling pressures and natriuretic peptide levels.

Exposure

Measurement of pulsatile arterial hemodynamics (brachial pulse pressure, aortic pulse pressure, aortic pulse wave velocity, and backward wave amplitude)

Comparator

Tissue Doppler echocardiography (TDE) alone (specifically E/E' at the medial annulus)

Outcome

Diagnostic accuracy (Area Under the Curve) for separating HFPEF from no HFPEFsurrogate

Main Result

Effect estimate: Net reclassification improvement 32.9%

p-value: p=<0.0001

Measures of pulsatile arterial hemodynamics, such as aortic pulse pressure, significantly improve the diagnostic accuracy for HFPEF when added to standard tissue Doppler echocardiography.
