Echocardiography reveals effects of pre-eclampsia
By Kate Madden Yee
Echocardiography of pregnant women with pre-eclampsia has shown that the condition negatively affects the heart's ability to relax between contractions, leading to inefficient pumping and an overworked heart, according to a study published in the Journal of the American College of Cardiology.

CCTA biomarker spots high-risk plaques in heart disease
By Abraham Kim
An increase in pericoronary adipose tissue attenuation -- a biomarker associated with inflammation -- on coronary CT angiography (CCTA) scans was associated with vulnerable plaques and may help predict the risk of heart disease, according to an article published online July 18 in JAMA Cardiology.

Cardiac MRI offers prognosis for hard-to-find infarctions
By Wayne Forrest
Cardiac MRI can play a critical role in helping to determine which patients suspected of having stable coronary artery disease could have an unrecognized myocardial infarction and an increased risk of an adverse cardiac event, according to a study published online recently in PLOS One.

Are patients with cardiac devices missing out on MRI?
By Brian Casey
Many patients who have older implanted cardiac devices are not getting brain and spine MRI scans, even though recent studies have shown that MRI can be safely performed on people with these legacy devices. That's according to a new article published July 2 in JAMA Neurology.
