What is Instantaneous Wave Free Ratio?
The Instantaneous Wave Free Ratio (iFR) is a medical measurement used to assess the severity of coronary artery disease. It focuses on the coronary arteries, which supply blood to the heart. iFR is a non-invasive method that evaluates blood flow and pressure in the arteries during a specific part of the heartbeat cycle. This helps in determining if there is a significant blockage that might require treatment.
iFR is needed when there is suspicion of coronary artery disease, which can lead to chest pain or heart attacks. If left untreated, blocked arteries can cause serious heart conditions. Modern approaches like angioplasty and stenting are available to address issues identified by iFR. These procedures help restore proper blood flow and prevent further complications.

Instantaneous Wave Free Ratio procedure Indications
The Instantaneous Wave Free Ratio (iFR) procedure is recommended by cardiologists to assess the severity of coronary artery disease. It is used when there is a need to determine the necessity for interventions like stenting or bypass surgery.
Chest Pain
Patients experiencing recurrent chest pain, especially during physical activity, may be considered for iFR. Doctors often find that stress tests or imaging show potential blockages. When medications fail to relieve symptoms, iFR helps decide further treatment.
Shortness of Breath
Shortness of breath during exertion can indicate coronary artery issues. If initial tests like ECG or echocardiograms suggest reduced blood flow, iFR can provide more clarity. This is particularly useful when symptoms persist despite medication.
Abnormal Stress Test Results
When a stress test reveals abnormal results, indicating possible heart blood flow issues, iFR helps in further evaluation. It is chosen when non-invasive tests do not clearly show the need for surgical intervention.
Intermediate Coronary Lesions
For patients with coronary lesions that are not clearly severe or mild, iFR aids in decision-making. Angiograms may show these ambiguous lesions, and iFR helps determine if they significantly affect blood flow.
Multiple Vessel Disease
In cases where multiple coronary arteries are affected, symptoms like chest pain and fatigue are common. iFR is used to assess which vessels require immediate attention when imaging shows widespread disease.
Post-Intervention Assessment
After procedures like angioplasty, patients may still experience symptoms. iFR is useful in evaluating the success of the intervention. It helps identify if further treatment is needed when symptoms persist.
How to Prepare for Instantaneous Wave Free Ratio?
Proper preparation for an Instantaneous Wave Free Ratio (iFR) test ensures accurate results and a smooth procedure. Following the guidelines helps minimise risks and complications.
- Medication Review: Consult your doctor about stopping NSAIDs, anticoagulants, and herbal supplements before the test.
- Fasting Requirements: Fast for at least 4-6 hours before the procedure if sedation is planned.
- Hydration: Drink clear fluids up to 2 hours before the procedure unless instructed otherwise.
- Clothing: Wear loose, comfortable clothing to the hospital for ease during the procedure.
- Transportation: Arrange for someone to drive you home post-procedure as you might feel drowsy.
- Medication List: Bring a list of all medications you are currently taking, including dosages.
- Health Conditions: Inform your doctor about any existing health conditions or allergies.
- Relaxation: Practice relaxation techniques to stay calm before the procedure.
Instantaneous Wave Free Ratio procedure (Step-by-Step)
Overview: The Instantaneous Wave Free Ratio (iFR) procedure is performed by cardiologists. It typically takes about 30-60 minutes and is done under local anaesthesia.
- Preparation: The patient is positioned comfortably on the procedure table. A local anaesthetic is applied to numb the area where the catheter will be inserted.
- Access Site: A small incision, about 1-2 cm, is made in the groin or wrist to access the artery. A catheter is then inserted through this incision.
- Catheter Insertion: A guide wire is threaded through the catheter to reach the coronary arteries. The patient may feel slight pressure but should not experience pain.
- Pressure Measurement: A pressure sensor on the catheter measures blood flow and pressure in the coronary arteries. The patient remains still during this process.
- Data Analysis: The cardiologist analyses the pressure readings to assess the severity of any blockages. The patient may feel some movement as the catheter is adjusted.
- Catheter Removal: Once the measurements are complete, the catheter and guide wire are carefully removed. The incision site is then bandaged.
- Recovery: The patient is monitored for a short period to ensure there are no complications. They may feel a bit drowsy from the anaesthesia.

Benefits of Instantaneous Wave Free Ratio procedure
The Instantaneous Wave Free Ratio (iFR) procedure is a non-invasive method used to assess the severity of coronary artery disease. It offers several advantages for patients.
- Reduced Discomfort: iFR does not require the use of adenosine, minimizing patient discomfort during the procedure.
- Quick Results: The procedure provides immediate results, aiding in faster decision-making for treatment.
- Cost-Effective: By avoiding adenosine, iFR can be more cost-effective compared to other methods.
- Improved Safety: The absence of adenosine reduces the risk of potential side effects associated with its use.
