Regadenoson stress for myocardial perfusion imaging.

Area of Science:

• Cardiology
• Nuclear Cardiology
• Pharmacology

Background:

• Noninvasive functional imaging is crucial for diagnosing hemodynamically significant coronary artery disease (CAD).
• Cardiac stress agents are essential for detecting abnormal myocardial perfusion indicative of coronary stenosis.
• Regadenoson is a widely used pharmacological vasodilator for cardiac stress testing.

Purpose of the Study:

• To provide an updated review of regadenoson stress testing for CAD assessment.
• To familiarize clinicians with regadenoson's properties, protocols, efficacy, and safety.

Main Methods:

• Review of pharmacological properties of regadenoson.
• Description of regadenoson stress protocols.
• Analysis of efficacy and safety data for regadenoson in CAD patients.

Main Results:

• Regadenoson is an effective and safe pharmacological stress agent.
• It is increasingly utilized as a primary or alternative stress modality.
• The review details its pharmacological actions and clinical application.

Conclusions:

• Regadenoson stress testing is a valuable tool for evaluating patients with suspected or known CAD.
• Understanding its use is important for clinicians managing CAD.
• The article offers comprehensive insights into regadenoson's role in myocardial perfusion imaging.
