Carotid ultrasound may help predict cardiac events

By Eric Barnes

Performing ultrasound studies of carotid intima-media thickness provides long-term prognostic value for adverse cardiac events, giving doctors important clues about who is at risk for a heart attack, according to a study published April 6 in the Journal of the American College of Cardiology.

4D MRI identifies abnormal flow patterns in thoracic aorta

By Wayne Forrest

Using 4D flow MRI to show abnormal systolic flows in the aortas of patients with a bicuspid aortic valve, researchers in California hope to identify patients at risk of developing ascending aortic aneurysm. Results of the research are published in the April issue of Radiology.

Cardiac cath delivers high radiation doses to operators

By Eric Barnes

The rapid development of new cardiac stents and other medical devices is opening up a world of possibilities for interventional procedures in the cath lab -- but it's also exposing equipment operators to ever-higher radiation doses.

PET-guided treatment reduces events in heart patients

By Wayne Forrest

Canadian and American researchers observed a "significant reduction" in cardiac events when using FDG-PET rather than standard methods of care to determine which patients receive revascularization therapy, according to research published in the April issue of the Journal of Nuclear Medicine.

High glucose signals contrast risk in angio patients

By Eric Barnes

Patients with high blood glucose levels are at increased risk of contrast-induced acute kidney injury after invasive coronary angiography, according to a just-published study of thousands of patients in the Journal of the American College of Cardiology.

Heart rate key to image quality in low-dose coronary CTA

By Eric Barnes

Heart rate control is an important factor for success in prospectively gated coronary CT angiography (CTA). But once patients are beta-blocked, the success rate is high and the doses are uniformly low, according to a new study by Swiss researchers.
