E/e' Diastolic Dysfunction Severity Grade Calculator

Grade diastolic dysfunction and estimate filling pressures using E/e' ratio. E/e' > 14 indicates elevated LVEDP.

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

Grade diastolic dysfunction and estimate filling pressures using E/e' ratio. E/e' > 14 indicates elevated LVEDP

Each component has a specific meaning:

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

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

How to Use

Enter the E/e' ratio for the scenario you are assessing. Grade diastolic dysfunction and estimate filling pressures using E/e' ratio. E/e' > 14 indicates elevated LVEDP. Use the e/e' diastolic result to inform your calculation.
