Regadenoson to Achieve Maximal Hyperemia for Fractional Flow Reserve in the Catheterization Lab
The purpose of this study is to determine if regadenoson is as safe and effective as adenosine when used in the cardiac catheterization lab during measurement of coronary flow reserve and fractional flow reserve. The study hypothesis is the assessment of Fractional Flow Reserve (FFR) in the catheterization lab can be performed with equivalent accuracy when hyperemia is induced with IV Regadenoson compared with IV Adenosine without compromising patient safety.

Medical and Biotech [MESH] Definitions
Coronary Artery Bypass
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
Internal Mammary-coronary Artery Anastomosis
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
Coronary-subclavian Steal Syndrome
A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.
Coronary Artery Disease
Pathological processes of CORONARY ARTERIES that may derive from a congenital abnormality, atherosclerotic, or non-atherosclerotic cause.
Abdominal artery that follows the curvature of the stomach. The right gastroepiploic artery is frequently used in CORONARY ARTERY BYPASS GRAFTING; MYOCARDIAL REVASCULARIZATION, and other vascular reconstruction.
Adenoscan® (adenosine) is an approved pharmacological stress agent indicated as an adjunct to thallium-201 myocardial perfusion scintigraphy in patients unable to exercise adequately. Th...
To exam the feasibility and accuracy of RTPE during vasodilator stress with 400micrograms of the A2A Receptor agonist Regadenoson for detection of significant coronary artery disease (CAD)...
We are studying the affect of caffeine on the sensitivity of detecting coronary artery disease (blockages in the blood flow to the heart) with adenosine tracer scans. Adenosine is a drug u...
The goal of this research is to determine the utility of Regadenoson (Lexiscan)for use as an imaging agent with cardiac MR. If found useful, it will help us establish a protocol for regade...
This is a pilot study to determine whether the drug regadenoson can be used during magnetic resonance imaging to assess regions of poor blood flow to the heart. The hypothesis of this stu...
Aims: Defining the clinical and physiologic significance of an intermediate coronary artery stenosis is aided by measurement of fractional flow reserve (FFR). Adenosine is the most common agent used i...
The A2(A) receptor agonist, regadenoson, is increasingly used as a vasodilator during nuclear myocardial perfusion imaging. Regadenoson is administered as a single, fixed dose. Given the frequency of...
Myocardial perfusion imaging using radionuclides is a well-established protocol for determining the diagnosis, prognosis, and management of coronary artery disease. Pharmacologic stress agents are use...
Since its approval by the Food and Drug Administration in 2008, regadenoson has become the most commonly used vasodilator in the United States. Previous reviews have summarized the pre-clinical and cl...
BACKGROUND: Caffeine attenuates the coronary hyperemic response to adenosine by competitive A(2A) receptor blockade. This study aims to determine whether oral caffeine administration compromises diagn...
