Gated SPECT best indicator for cardiac events
By Wayne Forrest
Myocardial perfusion abnormalities obtained after stress, as well as the extent of scar tissue detected by gated SPECT, are the best predictors of cardiac events in patients with suspected or known ischemic heart disease, according to a new Italian study.

Heart patients getting angio suffer less brain damage
By AuntMinnie.com staff writers
A new study to be published in the May/June issue of the Journal of Intensive Care Medicine indicates that patients who suffer cardiac arrests and then receive coronary angiography are twice as likely to survive without significant brain damage compared with patients who don't have the procedure.

ACC study: Most cardiac SPECT scans are appropriate
By Charlene Laino
ORLANDO - At a time of rising concerns about the overuse of medical imaging, researchers at the American College of Cardiology (ACC) annual meeting report that most nuclear cardiac scans are performed for appropriate indications. On the other hand, the highest percentage of inappropriate SPECT scans was performed in patients at low risk of heart disease.
