Adenosine Hyderabad | Focus Diagnostics

What is Adenosine?

Adenosine is a pharmacological agent that may be used during myocardial perfusion imaging as part of a nuclear medicine stress test. It temporarily affects blood flow in the coronary arteries, helping doctors assess blood supply to the heart muscle. This approach may be considered when a patient cannot perform adequate physical exercise for a conventional stress test.

Why may Adenosine testing be recommended?

A doctor may recommend an Adenosine-based stress test when myocardial perfusion imaging is required and exercise-based stress testing is unsuitable or insufficient. It may be used as part of an evaluation for suspected coronary artery disease, reduced blood supply to the heart muscle or other clinically relevant cardiac conditions.

What can the examination help evaluate?

Adenosine-assisted myocardial perfusion imaging helps evaluate blood flow to different regions of the heart muscle under pharmacological stress. When combined with a suitable nuclear medicine imaging protocol, it may help identify areas with reduced perfusion and support the assessment of coronary artery disease. Results must be interpreted alongside clinical findings and other cardiac investigations.

How is the examination performed?

The procedure is conducted under medical supervision. Adenosine is administered through an intravenous line according to the prescribed protocol while the patient's heart rate, blood pressure and ECG are monitored. A radioactive tracer may also be administered for gamma camera imaging of myocardial perfusion. The imaging protocol may include stress and resting acquisitions, depending on the clinical requirement.

Preparation before the examination

Patients should follow the preparation instructions provided by the nuclear medicine team. Caffeine-containing products, including coffee, tea, energy drinks and certain medications, may need to be avoided before the procedure. Do not stop prescribed medication without consulting the treating doctor. Inform the medical team about asthma, breathing problems, heart conditions, pregnancy or breastfeeding before the examination.

Understanding the report

The nuclear medicine report evaluates the distribution of the administered radiotracer in the heart muscle and identifies any areas showing reduced perfusion. Findings may provide information about myocardial blood flow and possible perfusion abnormalities. A qualified nuclear medicine physician or radiologist interprets the images, and the treating cardiologist should correlate the results with the patient's symptoms, medical history and other investigations.
