Cardiovascular Imaging

Coronary computed tomography angiography (CTA) is comparable to traditional invasive angiography for the detection and exclusion of lesion-specific ischemia, according to results of a study recently published online in the Journal of the American College of Cardiology.

New research presented at the American Stroke Association’s (ASA) International Stroke Conference 2016 suggests that brain imaging may be just as capable as time in identifying patients likely to benefit from stroke clot removal.

Obese individuals with nonalcoholic fatty liver disease (NAFLD) have higher instances of cardiovascular disease and heart failure, according to results of a study published online Jan. 26 in the journal Radiology.

A systematic review of seven studies found that quality improvement initiatives helped reduce inappropriate cardiac imaging. The most successful interventions featured physician audit and feedback capabilities.

CHICAGO—By using MRI and CT, researchers were able to analyze five preserved human hearts that were more than 400 years old and were found last year at an archeological site.

CHICAGO—A multivariable regression analysis of a prospective, population-based study found subclinical cardiac dysfunction was associated with subclinical brain disease.

The use of a mobile stroke treatment unit has helped the Cleveland Clinic's Cerebrovascular Center speed up time-sensitive treatment while reducing costs. 

A population-based cohort study of U.S. adults who did not have cardiovascular disease at baseline found that more than three-quarters of their myocardial scars were unrecognized by electrocardiography, cardiac MRI and clinical evaluation.

Three major trials have already established the 30-day clinical and economic soundness of ordering coronary CT angiography in evaluations of patients who show up in the emergency department complaining of chest pain. A new study shows the CCTA pathway to be similarly strong at the 12-month mark. 

A longitudinal, observational study of patients without cardiovascular disease at baseline found that the mass and volume of the left ventricle differs between men and women as they get older. The results were based on cardiac MRI taken at baseline and during a follow-up visit.

An analysis of patients with atrial fibrillation at the Cleveland Clinic found the yield of using myocardial perfusion imaging for detecting ischemia was low and did not significantly increase with increasing cardiovascular risk. Ischemia was not associated with mortality, either.

When implantable heart-help devices malfunction in cancer patients undergoing non-neutron-producing radiation therapy, don’t blame the malfunction on the therapy.
