Regadenoson is a medication used as a stress agent during myocardial perfusion imaging (MPI) to evaluate perfusion deficits in the heart caused by coronary artery disease (CAD). It works by dilating the coronary arteries and increasing blood flow to the heart.
The cost of regadenoson can vary depending on the brand, location, and insurance coverage. The brand name for regadenoson is Lexiscan, which can cost around $400-$500 for a single dose. However, the cost may be covered by insurance in certain cases.
Regadenoson has a rapid onset and reaches peak blood levels within 1 minute of injection. Its half-life is approximately 1.5 minutes, and it is primarily metabolized in the liver.
Some common side effects of regadenoson include headache, nausea, flushing, chest discomfort, shortness of breath, and dizziness. It may also cause allergic reactions, including anaphylaxis.
The Regadenoson stress test is a non-invasive cardiac imaging test that involves injecting the medication while the patient's heart is monitored for changes in blood flow. This test can help detect CAD and assess the severity of the condition.
Adenosine is another medication used as a stress agent during MPI. It works similarly to regadenoson by dilating the coronary arteries and increasing blood flow to the heart. However, it has a shorter half-life and may cause more side effects.
Myocardial Perfusion Imaging (MPI) is a non-invasive test that uses radioactive tracers and imaging technology to create images of the heart muscle. It can help diagnose and evaluate CAD, as well as assess the effectiveness of treatment.
Coronary artery disease (CAD) is a condition in which the arteries that supply blood to the heart become narrowed or blocked, leading to reduced blood flow to the heart muscle. This can cause chest pain, shortness of breath, and other symptoms.
Cardiovascular disease is a general term that refers to any condition that affects the heart and blood vessels. It includes CAD, as well as other conditions such as heart failure, arrhythmias, and valve disorders.
Heart disease is a broad term used to describe any condition that affects the heart, including both cardiovascular disease and other conditions such as congenital heart defects and cardiomyopathy.
