CAC score of 0 indicate low heart event risk, even in older people

AuntMinnie

PET/CT exams indicate that a coronary artery calcium (CAC) score of 0 is an accurate indicator of low coronary heart event risk -- even as a person ages, investigators have reported. A CAC score of 0 has long been accepted as a marker of very low risk of a cardiac event within the next five years, according to the group.

PET predicts adverse events in heart disease patients

AuntMinnie

PET imaging with nitrogen-13 (N-13) ammonia radiotracer can help predict major adverse cardiac events in patients with ischemic heart disease (IHD), according to a study published May 30 in Radiology: Cardiothoracic Imaging. Patients underwent the scans between January 2017 and January 2021.

Beware risk of adverse events associated with GBCAs

AuntMinnie

To make the situation more complicated, not all possible adverse events from GBCAs are noted in drug packaging, wrote a team led by Lu Wang , PhD, of Yantai Yuhuangding Hospital in Yantai, China. Adverse events occurred more frequently among women across all four drugs. Extra studies are needed to enhance the safety of GBCAs."

COVID-19 boosts cardiovascular event risk

AuntMinnie

Researchers using coronary CT angiography (CCTA) have reported that COVID-19 is associated not only with acute lung damage but also with rapid growth of plaque in the coronary arteries -- and thus an increased risk of cardiovascular events. Ge and colleagues' findings were published February 4 in Radiology.

AI-enhanced cardiac CT could help curb cardiovascular events

AuntMinnie

Eventually, these AI tools could reduce hospital length of stay and improve quality of life and health for people at high risk for cardiovascular events. Certain applications are progressing faster than others, however.
