Echocardiography predicts heart disease mortality when ECG does not
By
Reuters Health
NEW YORK (Reuters Health), May 22 - Exercise echocardiography can predict mortality and major cardiac events in patients with known or suspected coronary artery disease, but who have normal exercise electrocardiogram (ECG) results, new research indicates.

New echocardiography tool offers rapid, accurate assessment of LV function
By
Reuters Health
NEW YORK (Reuters Health), May 12 - Norwegian researchers have developed a new semiautomated tool for real-time 3D echocardiography, which offers "rapid and reproducible measurements of left ventricular [LV] volumes and ejection fractions," with good agreement compared with more conventional 3D echocardiography.

Biological dose measures promise new view of cardiac imaging risk
By
Eric Barnes
The development of biological radiation dose measurement portends a future of far greater accuracy in gauging the damage wrought by ionizing radiation in imaging exams. Two studies, focused on cardiac CT and conventional angiography exams, respectively, offer the potential of maximizing image quality while minimizing the potential radiation risk to the patient.

Coronary CTA with lower tube voltage reduces radiation exposure
By
Reuters Health
NEW YORK (Reuters Health), Apr 27 - A coronary CT angiography (CTA) protocol with reduced tube voltage results in a significant reduction in radiation exposure, and image quality in nonobese patients is not compromised, according to findings published in the April issue of the
American Journal of Roentgenology

Transesophageal echo informative in cryptogenic stroke
By
Reuters Health
NEW YORK (Reuters Health), Apr 23 - Transesophageal echocardiography (TEE) can shed light on contributing cardiogenic factors in patients with cryptogenic cerebral ischemia, according to German and U.S. researchers.

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.

ACC study: Coronary CTA tops other tests for long-term prognosis
By
Charlene Laino
ORLANDO - Coronary CT angiography (CCTA) is better than conventional risk scores and calcium scoring at predicting the long-term prognosis of patients with obstructive coronary artery disease, researchers reported at the annual meeting of the American College of Cardiology (ACC).

ACC study: Sequential CT delivers less radiation, good image quality
By
Edward Susman
ORLANDO - Using a sequential scanning mode during coronary CT angiography studies cuts radiation dose in half without impairing image quality compared to standard retrospective spiral data acquisition, according to a study presented at this week's American College of Cardiology (ACC) meeting.

Percutaneous cardiovascular procedures 'strikingly better' with radial access
By
Reuters Health
NEW YORK (Reuters Health), Mar 10 - In the real-world setting of contemporary clinical cardiology practices, adverse events following percutaneous cardiovascular procedures are substantially reduced by using radial artery access compared with using femoral access, investigators report in the March issue of
Heart

Diabetes renders coronary CTA more difficult, less successful
By
Eric Barnes
VIENNA - Diabetic patients have smaller vessels and larger coronary artery calcifications than nondiabetics, a combination that reduces the utility of coronary CT angiography (CTA), according to a new study from Italy.
