Atrial fibrillation (AF) is rare during dobutamine stress echocardiography (DSE), a routine exam for assessing coronary ischemia, but elderly patients and those with a history of paroxysmal AF are at an increased risk for arrhythmia during the test, a team of researchers from Boulogne, France, reported.

Instantaneous wave-free ratio (iFR) can safely guide revascularization decisions in left anterior descending (LAD) arteries with moderate stenosis, according to an analysis of the DEFINE-FLAIR study published in the Journal of the American College of Cardiology

An analysis of more than 5,000 heavy smokers who underwent CT scans revealed that male smokers experienced a greater burden of coronary artery calcium (CAC) while women tended to have higher volumes of thoracic aorta calcium (TAC). Both measures were associated with increased cardiovascular and all-cause mortality, researchers reported in JACC: Cardiovascular Imaging.

Patients with severe aortic regurgitation (AR) may be better off receiving valve operations before symptoms appear that “trigger” guideline recommendations for these surgeries, according to a new study in JACC: Cardiovascular Imaging.

The American Society of Echocardiography has released new guidelines for performing a comprehensive transthoracic echocardiography (TTE) examination. The recommendations, which were endorsed by 22 other cardiology/echocardiography societies from around the world, were published in the January edition of the Journal of the American Society of Echocardiography.

A CT angiography (CTA)-derived score that also incorporated the extent, location and composition of coronary plaque outperformed a model that focused only on the severity of stenosis, researchers reported Jan. 16 in JACC: Cardiovascular Imaging.

Sleeping less than six hours a night or experiencing poor-quality rest has been independently linked to an increased risk of subclinical multiterritory atherosclerosis, a team of Spanish researchers reported in the Journal of the American College of Cardiology Jan. 14.

Rivaroxaban failed to reduce the rate of early graft failure following coronary artery bypass graft (CABG) surgery compared to aspirin monotherapy, researchers reported in a substudy of the COMPASS trial published Jan. 14 in the Journal of the American College of Cardiology.

The RAPID neuroimaging platform can now be used in the U.S. to select stroke patients who are likely to benefit from endovascular thrombectomy. It is the first imaging platform to be cleared by the FDA as a patient selection tool for this clot removal procedure, according to iSchemaView, which developed the technology.

Research published in Stroke Jan. 10 suggests clinicians overestimate the severity of intracerebral hemorrhage (ICH) and underestimate the severity of acute ischemic stroke (AIS), resulting in a bias that could influence patients’ outcomes and treatment plans.

The Society of Cardiovascular Computed Tomography (SCCT) released updated guidelines for using CT imaging in patients undergoing transcatheter aortic valve replacement (TAVR).

Hypertensive patients who had periventricular white matter abnormalities progress from one brain scan to the next showed a six-fold increased risk of mild cognitive impairment, researchers reported Jan. 4 in Hypertension.
