Criteria to Guide Stress SPECT Need Work
DENVER -- Wide variations in the predictive power of appropriateness criteria for SPECT myocardial perfusion imaging warrants further research before lab accreditation becomes mandatory next year, researchers said here.

Guidelines for Stress SPECT Improve Outcomes
DENVER -- Adherence to the appropriateness criteria for stress SPECT myocardial perfusion imaging (MPI) can lead to better utilization and outcomes, but inappropriately ordered tests offer a less useful diagnostic yield, a single-center study found.

Stress Tests Clarified With CT Angiography
DENVER -- In patients with prior inconclusive stress tests and recurring chest pain, the use of coronary CT angiography (CCTA) can reduce downstream tests, a single-center retrospective study found.

Stress Imaging Drug Works As-Needed
DENVER -- The use of regadenoson (Lexiscan) is safe and can lead to cost and time efficiencies in patients undergoing exercise SPECT myocardial perfusion imaging.

Imaging Agent May Target LV Ablation Hot Spots
DENVER -- An imaging radiotracer used for cardiac innervation may identify left ventricular (LV) areas linked to tachyarrhythmic events, subsequently aiding ablation procedures, a small study found.

IV Drug KOs GI Discomfort of Stress Imaging
DENVER -- Aminophylline is safe and feasible with the newer generation vasodilator regadenoson (Lexiscan) in patients undergoing myocardial perfusion imaging (MPI), a new study demonstrated.

More Patients May Be Candidates for Exercise Stress
DENVER -- Primary care physicians appear more likely to select patients for pharmacological stress testing, even though these patients may be capable of an exercise stress test, a single-center study found.

Gender, Language May Sway Selection for Exercise MPI
DENVER -- English-speaking men are more likely to be referred for an exercise stress with SPECT myocardial perfusion imaging (MPI) versus a pharmacological stress test, a large database study found.

Age Alone May Put Symptom-Free People at Risk for Silent Ischemia
DENVER -- Traditional risk factors were predictive of silent ischemia in younger individuals, while age seemed to be the main predictor in those ages 74 and up, researchers found.

Workforce Challenges, Novel Tracers Top Meeting
DENVER -- It’s an interesting time to be a nuclear cardiologist, with both challenges and exciting new developments on the horizon, said the Mayo Clinic’s Todd Miller, MD, program chair of American Society of Nuclear Cardiology meeting.
