 - AF Ablation

Aggressive management of risk factors may be the key to improving patient outcomes following ablation for atrial fibrillation. Findings published Dec. 2 in the Journal of the American College of Cardiology suggest that in patients with a high body mass index and more than one cardiovascular risk factor, improved long-term outcomes are possible when several risk factors were addressed.

 - Stroke, endovascular. neuroimaging, neuro

Swiss researchers assessing carotid plaque stenoses using FDG-PET found the procedure accurate in detecting high-risk plaques. They also noted a strong correlation between uptake values of FDG and the presence of microembolic signals detected via transcranial Doppler.

 - ambulance, EMS

A review of out-of-hospital cardiac arrest cases found that patients who received basic life support in the ambulance had better survival and neurological performance compared with patients given advanced life support.

 - Stent

A biodegradable drug-eluting stent (DES) proved to be noninferior to durable-polymer DES and both showed benefits over bare-metal stents (BMS) in the BASKET-PROVE II clinical trial. The results published online Nov. 19 in Circulation also raise questions about triggers for late complications.

 - coronary artery calcium

Low-dose CT has become a mainstay for PET attenuation correction, but why not take it a step further by quantifying coronary artery calcium without adding any extra dose, according to an Ottawa Heart Institute study published ahead of print Nov. 20 in the Journal of Nuclear Cardiology.
