CCTA falls short in detecting culprit plaque
April 21, 2016 -- In a population of myocardial infarction patients spanning 10 years of clinical practice, coronary CT angiography (CCTA) showed only limited ability to detect culprit lesions in the coronary arteries that went on to cause heart attacks -- though its positive predictive value was perfect, researchers concluded.  Discuss

April 18, 2016 -- A U.K. research organization said it has launched a large study across the country that will involve scanning more than 100,000 participants to transform the way medicine looks at a wide variety of diseases including dementia, arthritis, cancer, heart attacks, and stroke.  Discuss
Cardiac cath radiation exacts toll on health personnel
April 14, 2016 -- Radiation from cardiac catheterization procedures is taking a heavy toll on cath lab personnel, according to a new study published April 12 in Circulation: Cardiovascular Interventions. Italian researchers found higher rates of orthopedic problems, cataracts, skin lesions, and even anxiety and depression in cath lab workers.  Discuss
CCTA halves adverse events in SCOT-HEART trial
April 12, 2016 -- A trial comparing the use of coronary CT angiography (CCTA) to standard care alone in more than 4,000 chest pain patients revealed sharply reduced event rates and fewer negative angiographies when CCTA was used to guide patient management, according to results published in the Journal of the American College of Cardiology.  Discuss
MRI rules out competing diagnoses in ARVC/D
April 11, 2016 -- Cardiac MRI (CMR) can diagnose arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) where other modalities fail, and it can even identify conditions that mimic the disease -- good news considering that timely treatment can often prevent sudden cardiac death.  Discuss
