Global Longitudinal Strain GLS Threshold Calculator

Assess subclinical LV dysfunction using GLS. GLS worse than -18% suggests subclinical dysfunction even with preserved EF.

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

Assess subclinical LV dysfunction using GLS. GLS worse than -18% suggests subclinical dysfunction even with preserved EF

Each component has a specific meaning:

  • GLS — The gls recorded for the scenario being assessed.

Note: Interpret the gls strain result against the thresholds and context described above.

How to Use

Enter the GLS for the scenario you are assessing. Assess subclinical LV dysfunction using GLS. GLS worse than -18% suggests subclinical dysfunction even with preserved EF. Use the gls strain result to inform your calculation.
