What E/e' ratio indicates diastolic dysfunction on stress?

A peak exercise E/e' >15 at rest or stress echo indicates elevated left ventricular filling pressures consistent with diastolic dysfunction, per ASE/EACVI guidelines.

Why is diastolic stress testing useful?

HFpEF often presents with normal resting parameters. Exercise-induced rise in E/e' unmasks occult diastolic dysfunction in patients with exertional dyspnea.

What other parameters support diastolic dysfunction on stress?

Peak tricuspid regurgitation velocity >2.8 m/s and lateral e' 15.

Diastolic Stress Test E/e' Threshold

Evaluate diastolic dysfunction with exercise stress echocardiography using E/e' ratio. A peak stress E/e' >15 identifies exercise-induced diastolic dysfunction and elevated filling pressures.

How It Works

Evaluate diastolic dysfunction with exercise stress echocardiography using E/e' ratio. A peak stress E/e' >15 identifies exercise-induced diastolic dysfunction and elevated filling pressures

Each component has a specific meaning:

E/e' ratio — The e/e' ratio recorded for the scenario being assessed.

Note: Interpret the diastolic stress e/e' result against the thresholds and context described above.

How to Use

Enter the E/e' ratio for the scenario you are assessing. Evaluate diastolic dysfunction with exercise stress echocardiography using E/e' ratio. A peak stress E/e' >15 identifies exercise-induced diastolic dysfunction and elevated filling pressures. Use the diastolic stress e/e' result to inform your calculation.
