Looking beyond the angiogram
An angiogram shows the shape of an artery. Coronary physiology assessment adds information about the pressure across a narrowing, helping the cardiologist consider whether it is affecting blood supply.
How FFR and RFR are used
A pressure-sensing wire is passed through the artery during catheter assessment. FFR uses measurements with medication that increases blood flow. RFR uses resting measurements. The result is interpreted alongside symptoms, other tests and the clinical situation.
Making a treatment decision
A narrowing does not automatically mean a stent is needed. The assessment can support discussion of medical treatment, intervention or further evaluation. A number alone does not replace clinical judgement.
Preparation and safety
Follow the hospital’s instructions for catheter procedures. Tell the team about allergies, kidney disease and all medicines. Discuss bleeding, contrast-related risks, medication effects and the possibility of artery injury before consenting.
Discuss your options
Bring your previous reports and medicine list to a consultation. Ask how this test or procedure would help in your situation, what alternatives are available and what follow-up you may need.
