AI with CTA may predict adverse events vs. other prediction scores
Coronary CTA assessed by machine learning was able to better distinguish patients who had an adverse event compared with the Coronary Artery Disease Reporting and Data System, or CAD-RADS, and other scores, according to a study published in Radiology.
Coronary wall thickness may be CAD risk factor in asymptomatic women
Among asymptomatic women, the use of MRI in measuring coronary vessel wall thickness may help determine risk for CAD, according to findings published in Radiology: Cardiothoracic Imaging.
Echocardiography use for acute myocardial infarction tied to higher costs, longer hospital stays, no clinical benefits
Higher rates of echocardiography use for patients with acute myocardial infarction were not associated with better outcomes and were tied to longer hospital stays and higher costs, according to a study recent published in JAMA Internal Medicine.
CAC level correlates with LV parameters in middle-aged patients
Middle-aged patients with high measurements of coronary artery calcium had higher left ventricular volumes, higher LV mass and worse LV diastolic function than those with low measurements, according to a study published in Circulation: Cardiovascular Imaging.
SURF: Transradial access superior to transfemoral access in 30-day clinical outcomes
In the randomized SURF trial of unselected patients with CAD with or without ACS, transradial access was associated with better 30-day clinical outcomes than transfemoral access, according to data presented at EuroPCR.
Aortic dissection rate low in pregnant women with Marfan syndrome
