Dobutamine Stress Echo Viability Assessment

Assess myocardial viability using low-dose dobutamine stress echocardiography. Biphasic response (improvement then worsening) indicates viability.

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 myocardial viability using low-dose dobutamine stress echocardiography. Biphasic response (improvement then worsening) indicates viability

Each component has a specific meaning:

  • Low-dose dobutamine stress echocardiography — The low-dose dobutamine stress echocardiography recorded for the scenario being assessed.

Note: Interpret the dse viability result against the thresholds and context described above.

How to Use

Enter the low-dose dobutamine stress echocardiography for the scenario you are assessing. Assess myocardial viability using low-dose dobutamine stress echocardiography. Biphasic response (improvement then worsening) indicates viability. Use the dse viability result to inform your calculation.
