What is regadenoson used for?

Regadenoson injection is used as a pharmacologic stress agent for radionuclide myocardial perfusion imaging (MPI) in patients unable to undergo adequate exercise stress. This medicine works by dilating the arteries of the heart and increase blood flow to help identify coronary artery disease.

What is regadenoson myocardial perfusion?

At our Institution, regadenoson was the first pharmacologic stressor introduced in clinical practice in 2013. Applied in a fixed dose of 400 ug/5ml as an intravenous bolus, it dilates coronary arteries reaching peak in circulation within 1-4 minutes increasing blood flow 2,4-fold above the baseline.

Is regadenoson same as adenosine?

Regadenoson is a more potent vasodilator than adenosine and exhibits selectivity for the coronary circulation relative to the renal, peripheral and mesenteric circulation in animals [5]. Adenosine is nonselective and causes negative chronotropic, dromotropic and inotropic effects via A1 receptors.

What is another name for regadenoson?

LEXISCAN® (regadenoson) injection is a pharmacologic stress agent indicated for radionuclide myocardial perfusion imaging (MPI) in patients unable to undergo adequate exercise stress.

What are the side effects of regadenoson injection?

Common side effects may include:

  • trouble breathing;
  • headache, dizziness;
  • chest pain or discomfort;
  • nausea; or.
  • flushing (warmth, redness, or tingly feeling).

What is regadenoson stress test?

The regadenoson stress test is the most used pharmacological stress test. It works by vasodilating the coronary arteries by stimulating the A2A receptors, increasing HR, and decreasing blood pressure.

Is adenosine the same as Lexiscan?

What is an Adenosine or Lexiscan nuclear scan? It is similar to the exercise nuclear stress test except for the fact that Adenosine or Lexiscan is used to stress the heart. Adenosine is infused over 4-6 minutes, while Lexiscan is given over a few seconds.

Is Lexiscan the same as adenosine?

What should I avoid after a nuclear stress test?

Caffeine can alter the test results. Do not eat chocolate or drink coffee, tea, soda, colas or other caffeinated beverages such Mountain Dew or energy drinks. If you are unsure, do not drink it. See the table below for more details.

How long do adenosine side effects last?

Despite the short half-life of adenosine, 10.6% of the side effects occurred not with the infusion of Adenoscan but several hours after the infusion terminated. Also, 8.4% of the side effects that began coincident with the infusion persisted for up to 24 hours after the infusion was complete.

Will adenosine stop your heart?

While adenosine can slow conduction through the AV node, it does not affect accessory pathways. In such cases, this can cause severe tachycardia that can deteriorate to a non-perfusing rhythm, leading to cardiac arrest.
