LVEDP from Doppler E/e' Estimation

Noninvasively estimate LVEDP using E/e' ratio. LVEDP = 11.4 + (1.24 x average E/e') per validated regression equations.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Noninvasively estimate LVEDP using E/e' ratio. LVEDP = 11.4 + (1.24 x average E/e') per validated regression equations

Each component has a specific meaning:

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

Note: Interpret the lvedp doppler result against the thresholds and context described above.

How to Use

Enter the E/e' ratio for the scenario you are assessing. Noninvasively estimate LVEDP using E/e' ratio. LVEDP = 11.4 + (1.24 x average E/e') per validated regression equations. Use the lvedp doppler result to inform your calculation.
