Coronary CT angiography is commonly used to assess patients at low or intermediate risk of CAD but is less effective in high-risk patients with an increased presence of coronary calcifications and stents due to the “blooming” effect they have on imaging.

Prior chest imaging can sometimes be just as predictive of adverse events after surgery as updated imaging, according to new data set to be presented at the annual conference of the American College of Cardiology on March 5. 

Dual source CT scanners can eliminate the need for beta blockers to control heart rates during coronary CTA exams.  

A CCTA-based radiomics method was recently found to be more accurate in identifying potentially problematic plaques than conventional CCTA anatomical parameters alone.

While the ACC/AHA 2021 Chest Pain Assessment Guidelines included cardiac CT angiography as a top level recommendation, gaps in evidence still need to be filled.

Not only does the low-volume contrast protocol preserve supplies, it also protects patients who might be vulnerable to adverse reactions and/or side effects from contrast use. 

Researchers examined data from nearly 2 million patients, sharing their full findings in JACC: Cardiovascular Imaging.

Primary aldosteronism (PA) is one the single most common causes of hypertension, but identifying patients with PA—and knowing which ones may benefit from a surgical treatment—can be quite challenging.
