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

Calculate aortic valve area using Gorlin equation from cardiac catheterization data: cardiac output, gradient, and heart rate

Each component has a specific meaning:

  • Gorlin equation from cardiac catheterization data: cardiac output — The gorlin equation from cardiac catheterization data: cardiac output recorded for the scenario being assessed.
  • Gradient — The gradient recorded for the scenario being assessed.
  • Heart rate — The heart rate recorded for the scenario being assessed.

Note: Interpret the gorlin ava result against the thresholds and context described above.

How to Use

Enter the Gorlin equation from cardiac catheterization data: cardiac output, gradient, heart rate for the scenario you are assessing. Calculate aortic valve area using Gorlin equation from cardiac catheterization data: cardiac output, gradient, and heart rate. Use the gorlin ava result to inform your calculation.
