Diagnostic Imaging and Biomarkers in Cardiology News

 
 
  • SCCT Motion-Correction Algorithm Ups Cardiac CT Image Quality Early results from the multinational VICTORY trial suggest that an intracycle motion-correction algorithm may eliminate troublesome motion artifacts and improve interpretation of coronary CT angiography scans.
  • 'Healthy Obese' More Likely to Have Subclinical CVD A new study using CT to assess coronary calcification suggests there might be no such thing as "healthy fat." Obese but metabolically healthy individuals were more likely to have calcification than normal-weight individuals.
  • ECR Coronary Artery Calcium Scores Vary Widely Among Scanners Different brands of CT scanners result in different coronary artery calcium scores, possibly misclassifying up to 6.5% of patients, according to a new study.
  • ESC Urges Cardiologists to Be Aware of Radiation Doses In a new position paper, the European Society of Cardiology calls for cardiologists to be more aware of radiation doses in cardiac imaging tests and to make sure these tests are ordered appropriately.
  • New Appropriate-Use Criteria Issued for Tests in Stable CAD Cardiology groups have created a new document ranking seven common tests used for diagnosis and risk assessment in stable ischemic heart disease, side by side.
  • AHA Coronary Artery Calcium Density May Help Predict CVD Risk In patients at intermediate risk of cardiovascular disease, coronary artery calcium density may improve risk prediction, a new study suggests; however, it is too early to recommend widespread CAC testing.
  • AHA Nitrites No Cure for Reperfusion Injury From MI Stenting Although a sodium-nitrite infusion didn't limit infarct size, there was a signal of possible benefit in one patient subgroup.
  • New CV Risk-Assessment Guidance Counts Stroke With CHD Risk The document released by the AHA and ACC promotes evaluation of both 10-year and lifetime risk; its revamped risk-prediction equations now account for variation by race and gender.
  • TCT Penile-Artery Angioplasty Gets Second Look for ED A small pilot trial is picking up where the ZEN trial of drug-eluting stents for ED left off, this time trying plain-old balloon angioplasty in the penile arteries.
  • Alert Cardio Imaging Agent Placed on FDA Watch List The agency received reports possibly linking regadenoson to fatal myocardial infarctions. The FDA will try to determine whether there is a causal relationship.
  • Lean or Obese, Low Inflammation Predicts Metabolic Health Adults with normal inflammatory-marker levels were metabolically healthy regardless of body size in a new study; abnormal inflammatory markers may identify obese individuals at higher risk of disease.
  • AUC Sharpen SPECT Chest-Pain Risk Stratification in Large Series Inappropriate use degrades and appropriate use sharpens the prognostic power of SPECT myocardial perfusion imaging in chest pain evaluation in community-based setting, a study finds.
  • Aliskiren, no impact on atherosclerosis in AQUARIUS In a new setback for the drug, the renin-inhibitor has failed to demonstrate atherosclerosis regression in patients with prehypertension.
  • CoreValve use paused by German courts Edwards, which successfully won a recent patent battle against Medtronic, says it is "reaching out" to make sure doctors unaccustomed to using the Sapien get the training they need.
  • Does Remnant Cholesterol Raise CRP? The novel association between nonfasting remnant cholesterol with CRP levels and ischemic heart disease "could be explained by remnant cholesterol causing atherosclerosis, a disease with a known inflammatory element," say researchers.
  • Resource sharing helps small practices manage chronic illness Physicians in independent practice associations used patient registries, nurse care managers, and other methods of treating the chronically ill more so than their non-IPA peers. But will that help them succeed in accountable-care organizations?
  • GE Healthcare recalls imaging systems after patient death One patient has died as a result of injuries sustained while being scanned on an Infinia Hawkeye 4 nuclear medicine system, prompting a class 1 recall of this system and others.
  • Physicians can track industry payments using CMS app Physicians aren't required to use the mobile app, but the CMS says it will help them double-check what drug and device makers report under the ACA's "sunshine" provisions.
  • India poised to revoke pioglitazone ban The Indian government's ban on pioglitazone may soon be revoked if the government follows the advice of the Drug Technical Advisory Board, which has recommended that pioglitazone be put back on the market.
  • SCCT Cardiac CT Can Characterize Plaque, Guide TAVR
