Cancer risk from radiation during cardiac CT scans studied

An analysis based on computerized simulation models suggests that the lifetime risk of cancer associated with radiation exposure from a computed tomography (CT scan) coronary angiography varies widely, with the risk greater for women and younger patients, according to a study in the July 18 issue of JAMA .

Scientists have captured on video the intracellular version of a postal delivery service

Reporting in the journal Biochemical and Biophysical Research Communications (BBRC), bioengineering researchers at UC San Diego published videos of a key message-carrying protein called paxillin moving abruptly from hubs of communication and transportation activity on the cell surface toward the nucleus.

Heart-assist device gives Culver City man a better quality of life

Mark Heiner of Culver City reads books, paints artistically, takes walks and does laundry – activities that would be considered routine except for the fact that a four-pound disk implanted in his abdominal cavity is keeping his blood flowing.

Study of VentrAssist heart support device as a bridge to transplantation

Doctors at UPMC have begun a study using an investigational cardiac device, the VentrAssist, Left Ventricular Assist System (LVAD) to see whether it can be used safely and effectively in patients with end-stage heart failure.

Screening men over 65 for abdominal aortic aneurysms could save lives

Between 5% and 10% of men aged 65 to 79 have abdominal aortic aneurysms, but don’t know it.

Catheter-based aortic valve replacement is set to take off

Twenty years ago, few interventional cardiologists could have imagined that during their professional careers it would be possible to replace a diseased aortic valve using catheter-based techniques, rather than open-chest surgery.

Percutaneous aortic valve replacement safe

Catheter techniques are expanding into new territory, successfully aiding in the replacement of narrowed, calcified aortic valves in patients too sick to withstand open-chest surgery.

MDCT eliminates need for catheter angiography for aortic injury diagnosis

Contrast-enhanced 64-MDCT that definitively reveals acute trauma to the aorta does not need confirmation from invasive catheter angiography, which saves valuable time in treating patients in trauma centers, according to a new study by researchers from the Medical University of South Carolina in Charleston.

Regular ultrasound screening for abdominal aortic aneurysms saves men's lives

Regular ultrasound screening for abdominal aortic aneurysms can sharply reduce the likelihood of dying from a ruptured aneurysm among men age 65 and older, according to a new review of recent studies.

Endovascular repair of thoracic and abdominal aortic diseases as an alternative to open surgery in patients at high surgical risk

World Congress of Cardiology Report - Acute aortic syndromes, such as large thoracic and abdominal aortic aneurysms with impending rupture, complicated acute type B dissections, traumatic rupture of thoracic aorta, still represent life-threatening conditions.

One of the largest Japanese cardiovascular trials confirms angiotensin receptor blockade protects people who have a wide range of cardiovascular diseases

The first controlled large-scale intervention trial of angiotensin receptor blockade in Japanese patients has confirmed that the cardiovascular protective effects of the drug valsartan is greater than to those seen with other therapies giving the same level of blood pressure control.

Mechanics of atherosclerosis

Atherosclerotic narrowing and hardening of coronary arteries typically appear first at vessel branches, and a study in the October issue of Cellular Signalling reports that the type of mechanical stretching found at those branches activates a cellular protein known to damage cells.
