Imaging

 - Question Direction

Guidelines offer some direction on the appropriate use of repeated coronary CT angiography (CCTA), but how often is it actually catching anything of significance? Published July 18 in Circulation: Cardiovascular Imaging, this was the question posed by researchers hoping to guide future use.

 - surgery

The presence of late gadolinium enhancement (LGE) on cardiac MR predicted perioperative risk and worse survival in patients with severe aortic stenosis who were to undergo surgical aortic valve replacement, according to a study published in the July 15 issue of the Journal of the American College of Cardiology.

 - Neon Heart

First-in-human study of an investigational radiotracer, F-18 LMI1195, shows clear imaging of myocardial innervation via the norepinephrine transporter system—tipping off potential adverse cardiac events, according to a study published July 3 in the Journal of Nuclear Medicine.

In treating ischemic stroke, door-to-needle times are important for providing stroke patients with tissue plasminogen activator. However, the time between imaging the brain and initiating therapy appears to the most vulnerable to potential delays.

 - Neon Heart

Rates of cardiovascular testing among incident heart failure patients varied widely in a study published June 18 in the Journal of the American College of Cardiology: Cardiovascular Imaging. One-fifth of patients were not tested at all during the four months before and the six months following their hospitalization for heart failure.

While imaging technologies and medical procedures for treating cardiac conditions have improved, there are risks, particularly to the youngest patients. Researchers found that children with heart disease who have the most difficult treatment paths face the greatest long-term risks for cancer.

MPI finds more CAD five years after treatment

Stress myocardial perfusion scintigraphy (MPS) when conducted five years following percutaneous coronary intervention (PCI) has the potential to pinpoint addition disease in more than half of patients, according to a study published ahead of print May 14 in JACC: Cardiovascular Interventions.

3D CMR comparable to MPS for estimating ischemic burden

3D myocardial perfusion cardiovascular magnetic resonance MR (CMR) adds depth to looking at ischemic burden in heart patients, according to a recently published study. It one day may serve as an alternative to imaging techniques that rely on ionizing radiation.

Physicians can use incidental findings on chest CTs to identify patients at risk of cardiovascular disease. Researchers reported online May 27 in Radiology that a validated, imaging-based risk predictor had good discriminative ability and calibration for stratifying at-risk patients.

Stress CMR predicts heart disease risk in obese patients

Stress cardiac magnetic resonance (CMR) imaging may help physicians risk stratify obese patients for cardiovascular disease, according to a study that found stress CMR to be feasible in this patient population.

Radiotracer acts as marker, predictor in aortic stenosis

The radiotracer 18F-sodium fluoride (18F-NaF) serves as a biomarker of calcification activity in patients with aortic stenosis and may predict disease progression, according to a study published in the March issue of Circulation: Cardiovascular Imaging.

Fragmented care may increase the likelihood of Medicare beneficiaries receiving four or more CT head scans within a year of an ischemic stroke, according to a study that found regional and racial variability in high-intensity CT use.

Stress testing in asymptomatic patients may not be beneficial

Few asymptomatic patients with acute coronary syndrome who undergo PCI followed by stress imaging may actually need revascularization, raising questions about the benefits of stress imaging, a study published online March 31 in Circulation: Cardiovascular Imaging found.

 

SCAI lists 5 procedures to avoid in heart patients

Patients should not undergo stress testing after PCI unless there is a clinical indication for this procedure, the Society for Cardiovascular Angiography and Interventions (SCAI) recommends. SCAI issued a list of procedures that should be avoided in patients with or at risk for cardiovascular disease.

MPI use drops by 51 percent over 5-year span

The use of myocardial perfusion imaging (MPI) has declined over the past few years, researchers wrote in a letter published March 26 in JAMA. The decrease, they explained, could be due to changing physician behavior as well as a lower incidence of coronary disease.

Carotid atherosclerosis score may help predict stroke risk

An elevated carotid atherosclerosis score (CAS) could indicate increasing plaque progression and a disrupted luminal surface and ultimately help stratify stroke risk, a study published online March 13 in the Journal of the American College of Cardiology: Cardiovascular Imaging found.

CMR may be better than SPECT at diagnosing CAD in women

When diagnosing coronary artery disease (CAD) in women, cardiovascular magnetic resonance (CMR) may be a better option than SPECT, according to a study published in the March 11 issue of Circulation. The study found CMR to be more sensitive than SPECT in both sexes and there are no significant differences between the sexes with CMR, unlike SPECT.

Pre-hospital stroke alerts expedite CT imaging

The use of pre-hospital stroke alerts by emergency medical services (EMS) may mean patients can get life-saving treatment faster. A study published in the March issue of Neurosurgery found that EMS personnel who identified patients having strokes and notified hospitals allowed patients to skip the emergency department and have a CT scan as soon as possible.

ECGs as part of athlete screenings less favored in U.S.

Although a majority of medical experts recently polled believe young athletes should be screened for cardiac disease before participating in sports, less than half of providers in the U.S. say electrocardiograms (ECGs) should be included, according to an article published March 6 in the New England Journal of Medicine. The majority of their European counterparts, on the other hand, do favor ECGs as part of the process.
