Cardiac Computed Tomography
AI-identified CAC via routine CT scan may reveal risk for heart attack, stroke
Routine CT scans could serve as a useful tool to identify patients at high risk for atherosclerotic CVD when paired with a deep learning algorithm that calculated coronary artery calcium scores, researchers reported.
Management of low-risk patients with pulmonary embolism differs based on CT scan findings
Patients presenting with low-risk pulmonary embolism are managed in different ways based on CT scan findings and not clinical risk factors, according to study results published in JAMA Network Open.
Coronary CT may be best diagnostic strategy when evaluating stable chest pain
For adults with stable chest pain, coronary CTA may be as useful as direct invasive coronary angiography and may be the best diagnostic strategy vs. stress testing and single-photon emission CT myocardial perfusion imaging, data show.
On-site FFR-CT using machine learning reduces invasive procedures in stable CAD
NEW ORLEANS — In patients with stable CAD, use of CT-derived fractional flow reserve with on-site machine learning reduced invasive coronary angiography in those who did not need it, but did not improve other outcomes, researchers reported.
Pretreatment chest CT may predict cardiotoxic events from large B-cell lymphoma treatment
Automatic calcium scoring with nongated chest CT was prognostic of major adverse and cardiotoxicity-related CV events in patients with large B-cell lymphoma undergoing anthracycline-based chemotherapy, researchers reported.
FDA clears noninvasive AI-powered coronary anatomy, plaque analyses
HeartFlow announced it has received FDA 510(k) clearance on two new noninvasive artificial intelligence-powered coronary artery anatomy and plaque analyses based on coronary CT angiography.
New technique identifies ‘hot’ disease in arteries that can lead to CV events
Using noninvasive 18F-sodium fluoride PET and coronary CTA to detect “hot” disease in arteries, researchers were able to predict which patients with recent MI would have recurrent coronary events.
CT ‘safe alternative’ to coronary angiography for CAD diagnosis
In patients with stable chest pain and intermediate pretest probability of CAD, risk for major adverse CV events was similar after CT or invasive coronary angiography, with fewer procedure-related complications with an initial CT strategy.
Many factors must be considered when choosing imaging test for chest pain
For patients with chest pain, there is no single imaging test that will provide the perfect diagnosis for all, according to a speaker at the American Society for Preventive Cardiology Congress on CVD Prevention.
Educating patients on CT results increases adherence, reduces chest pain
Providing brief education to patients on CT results leads to patient adherence and reduces the future likelihood of noncardiac chest pain, researchers reported.
