Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

New protocol cuts costs, time for CMR imaging

A simplified cardiac magnetic resonance (CMR) protocol using a contrast agent allowed clinicians in Peru to diagnose heart ailments more quickly and cheaply, a new study found. The results, published online Aug. 29 in the Journal of the American Heart Association, highlight a potential pathway to realizing the benefits of CMR in developing nations.

UK's NHS: 22% of patients wait more than 6 weeks for imaging tests

Recent statistics from the National Health Service (NHS) show that almost a quarter of patients wait more than six weeks for key diagnostic tests such as MRI and CT scans, the BBC reported on Aug. 27.

Novel cardiac imaging biomarker could predict risk of coronary inflammation, heart attack

A team of international researchers has developed a new imaging biomarker able to non-invasively predict a patient’s risk of coronary inflammation and heart attack, according to research published Aug. 28 in The Lancet.

This measure is being tested in trials to see if it can accurately predict which coronary artery lesions will progress to cause heart attacks. The method also can show a reduction in risk with therapy, as seen here.

FAI helps quantify vascular inflammation, predict future CVD events in cardiac imaging patients

The addition of perivascular fat attenuation to routine coronary computed tomography angiography (CTA) improves risk stratification in heart patients, according to research presented at the European Society of Cardiology (ESC)’s annual symposium in Munich, surpassing current prognostic models to re-classify and predict cardiac deaths with more accuracy.

Study Shows Improved Quality of Life and Reduced Symptoms In Patients Treated with Medtronic Cryoballoon

DUBLIN and MUNICH — August 28, 2018 — Medtronic plc (NYSE:MDT) today announced new findings from the CRYO4PERSISTENT AF clinical trial demonstrating improved quality of life, reduced symptoms from abnormal heart rhythms, and low incidence of reinterventions and repeat ablation procedures.

CT angiography may improve treatment decisions for stable chest pain

Patients with stable chest pain who were evaluated with coronary CT angiography (CTA) were significantly less likely to experience a heart attack or die from coronary heart disease (CHD) within five years compared to individuals who received standard testing, researchers reported in the New England Journal of Medicine.
