MINNEAPOLIS, Oct. 2 /PRNewswire/ -- A new analysis reaffirms that Lexiscan® (regadenoson) Injection, the first selective A2A adenosine receptor agonist approved for use as a pharmacologic stress agent in radionuclide myocardial perfusion imaging (MPI) in patients unable to undergo adequate exercise stress, requires infrequent use of the drug aminophylline to reverse its effect in the case of adverse events. The low use of aminophylline demonstrates that Lexiscan is...

A U.S. doctor is calling for more research on whether medical imaging risks justify the risks of some medical imaging. Dr. Michael S. Lauer of the National Heart, Lung and Blood Institute -- part of the National Institutes of Health in Bethesda, Md. -- says more research is needed to demonstrate whether the use of cardiovascular imaging tests, such as myocardial perfusion imaging and Computed tomography scans, improve patient outcomes. No large-scale, randomized trials have shown that imaging...

Increased use of medical scans could have a dangerous impact on the health of Americans under age 65, according to a recent study. Writing in The New England Journal Of Medicine, Dr. Reza Fazel of Emory University and colleagues, found that the cumulative amount of radiation from repeated scans could pose a health risk to patients. Fazel and his team conducted a three-year study of almost 1 million Americans between the ages of 18 and 64. The study was based on data from a 2005-2007 survey of...

From CT scans to nuclear stress tests, America is receiving skyrocketing rates of radiation through medical imaging. Experts say research is necessary to determine whether the benefits outweigh the known cancer risks of radiation. In a study including about 1 million adults between 18 and 64, nearly 70 percent experienced medical imaging between July 2005 and December 2007, doubling the average expected dose of radiation exposed naturally. The number of CT scans given has quadrupled since...

The Radiological Society of North America (RSNA) reaffirmed its commitment to patient safety today in responding to a study and accompanying perspective on radiation dose from medical imaging procedures in the New England Journal of Medicine (NEJM).In "Exposure to Low-Dose Ionizing Radiation from Medical Imaging Procedures," Reza Fazel, M.D., M.Sc., and colleagues reported that imaging procedures are a key source of ionizing radiation exposure in the U.S. and that repeat exams can result in...

PALO ALTO, Calif., Aug. 25 /PRNewswire/ -- CardioDx, a cardiovascular genomic diagnostics company, announced today that the company has successfully completed its multicenter validation study for Corus(TM) CAD, the first and only gene expression test to quantify the likelihood of obstructive(1) coronary artery disease (CAD) in patients with stable chest pain. The company expects to present results of the study by the end of 2009, and will publish the results in 2010. Following completion...

Researchers may be able to predict future severe heart attacks in patients with known, stable coronary artery disease (CAD) using coronary calcium scoring, according to a new study. "The amount of calcium in the coronary vessels, as measured by CT, is of high predictive value for subsequent serious or fatal heart attack in these patients, independent of the patient's age, sex and other coronary risk factors," the study's lead author, Marcus Hacker, M.D., of the Department of Nuclear...

German researchers say they may be able to predict future severe cardiac events in patients with known coronary disease using coronary calcium scoring. Coronary artery disease is a condition in which plaque -- cholesterol, calcium, fat and other substances -- builds up inside the arteries that supply blood to the heart. When plaque builds up in the coronary arteries, blood flow to the heart is reduced and may lead to arrhythmia, heart attack or heart failure. Lead author Dr. Marcus Hacker...
