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 peak systolic strain rate from speckle-tracking echocardiography as a load-independent marker of myocardial contractility

Each component has a specific meaning:

  • Speckle-tracking echocardiography as a load-independent marker of myocardial contractility — The speckle-tracking echocardiography as a load-independent marker of myocardial contractility recorded for the scenario being assessed.

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

How to Use

Enter the speckle-tracking echocardiography as a load-independent marker of myocardial contractility for the scenario you are assessing. Calculate peak systolic strain rate from speckle-tracking echocardiography as a load-independent marker of myocardial contractility. Use the strain rate result to inform your calculation.
