FFR-CT Ischemia Threshold 0.80

Apply the fractional flow reserve derived from CT (FFR-CT) threshold of <=0.80 to identify hemodynamically significant coronary lesions and guide revascularization decisions.

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

Apply the fractional flow reserve derived from CT (FFR-CT) threshold of <=0.80 to identify hemodynamically significant coronary lesions and guide revascularization decisions

Each component has a specific meaning:

  • CT threshold of <=0 — The ct threshold of <=0 recorded for the scenario being assessed.

Note: Interpret the ffr-ct threshold result against the thresholds and context described above.

How to Use

Enter the CT threshold of <=0 for the scenario you are assessing. Apply the fractional flow reserve derived from CT (FFR-CT) threshold of <=0.80 to identify hemodynamically significant coronary lesions and guide revascularization decisions. Use the ffr-ct threshold result to inform your calculation.
