Patients with peripheral arterial disease may need cardiac imaging
By Edward Susman
As many as one in five patients being treated for peripheral arterial disease have concurrent -- but silent -- asymptomatic coronary artery disease that's severe enough to require invasive procedures, according to a study presented at the RSNA meeting earlier this month.

MRI shows age- and gender-based differences in myocardial motion
By Eric Barnes
People who suspect that men's and women's hearts march to different drummers now have proof from cardiac MRI. Myocardial motion is strongly influenced by gender as well as age, according to researchers from Freiburg, Germany.

Tissue Doppler ratio predicts cardiac events in hypertensive patients
By Reuters Health
NEW YORK (Reuters Health), Dec 10 - Estimates of left atrial filling pressure, drawn from Doppler studies of the left ventricle, can strongly predict a first cardiac event in hypertensive patients, according to a report in the November 26 European Heart Journal.

Echocardiography test beats SPECT for predicting problems after MI
By Reuters Health
NEW YORK (Reuters Health), Dec 7 - Myocardial contrast echocardiography is superior to nitrate-enhanced SPECT in predicting cardiac death and other cardiac events after acute myocardial infarction, say researchers from the U.K. in the November 1 American Journal of Cardiology.

Contrast dose halved in coronary CTA
By Eric Barnes
CHICAGO - Contrast doses for CT angiography (CTA) are too high, but they can be lowered substantially with the right equipment and careful attention to technique, according to researchers from Charité University Medical School in Berlin.

Trial can't prove PCI to be noninferior to CABG for diabetics with complex CAD
By Reuters Health
NEW YORK (Reuters Health), Dec 1 - A large study of revascularization strategies in diabetics with multivessel coronary artery disease, which set out to show that angioplasty is not inferior to bypass surgery for these patients, could not prove its hypothesis.

Coronary CTA edges CMR in a tight race
By Eric Barnes
CHICAGO - In a head-to-head comparison of two closely watched modalities, low-dose dual-source coronary CT angiography (CTA) outperformed cardiac MR (CMR) in sensitivity, specificity, and negative predictive value. But 1.5-tesla CMR countered with better specificity and positive predictive value.

Chest pain: Simple criteria pinpoint who benefits most from cardiac CT angiography
By Reuters Health
NEW YORK (Reuters Health), Nov 30 - Women younger than 65 years and men younger than 55 with acute chest pain benefit most from cardiac CT angiography for suspected acute coronary syndrome, results of a study indicate.

Automated segmentation could improve fetal heart echo
By Eric Barnes
A new method of segmenting the fetal heart with echocardiography could improve the evaluation of congenital heart defects compared to the time-consuming manual segmentation in use today, according to researchers from the U.K.

In patients with stable chest pain, CT is more often diagnostic than exercise ECG
By Reuters Health
NEW YORK (Reuters Health), Nov 2 - Unlike exercise electrocardiography (XECG), CT angiography is "nearly always" feasible and diagnostic in patients with stable chest complaints, researchers say in the October issue of the journal Heart.

Contrast ultrasound may spot early signs of atherosclerosis
By Erik L. Ridley
Contrast-enhanced ultrasound (CEUS) can allow for reliable quantification of the neovascularization of the carotid artery vasa vasorum, enabling early identification of a condition that can be a precursor to atherosclerosis, according to a presentation at this week's Advances in Contrast Ultrasound: ICUS Bubble Conference in Chicago.
