Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

EuroPCR: Resolute trends positively vs. Xience in all-comers trial

Medtronics Resolute zotarolimus-eluting stent was found to be as safe and effective as Abbott Vasculars Xience V everolimus-eluting stent in a predominantly off-label population, based on the results of the RESOLUTE all-comers trial, presented Tuesday by Patrick W. Serruys MD, PhD, at EuroPCR in Paris. Slides

The Back Page: Despite Higher Up-Front Cost, Cardiac PET Has Its Place

Given the current SPECT isotope shortage, what role does PET play in cardiology from a business and clinical standpoint? Compared with SPECT imaging, PET is a relatively expensive technology. Therefore, could an investment in PET be the right choice for some?

JAMA: More hypertensive patients in control, but no rate decrease

While the U.S. met the goal of Healthy People 2010 by having 50 percent of hypertensive patients having control over their blood pressure, the overall rates of hypertension are not decreasing, according to a study published May 26 in the Journal of the American Medical Association.

Web-based tool makes cardiac procedure risks more transparent

In 2006, John A. Spertus, MD, and his colleagues at the Mid America Heart Institute of Saint Lukes Hospital in Kansas, Mo., engineered a web-based toolPREDICT (Patient Refined Expectations for Deciding Invasive Cardiac Treatments)to scientifically enhance the informed consent process and provide better procedural outcome transparency to patients.

JDI: Chest x-ray CAD with CT correlation yields good lung nodule detection

When used in conjunction with an experienced radiologist, the use of computer-aided detection (CAD) for lung nodule detection on chest radiograph with CT angiography (CTA) correlation presents very good sensitivity, specificity and accuracy, according to a study published online March 31 in the Journal of Digital Imaging.

Regadenoson with low-level exercise reduces side effects

In a routine clinical setting, the pharmacologic stress agent regadenoson with and without low-level treadmill exercise is safe and well tolerated. Those patients who exercised had fewer side effects and a drop in blood pressure, according to a study published online April 23 in the Journal of Nuclear Cardiology.
