Electron-beam computed tomography - a more accurate replacement for coronary catheterizations

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death, according to research by a Saint Louis University radiologist published last month in Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

C-reactive protein in atherosclerotic lesions: its origin and pathophysiological significance

New research shows that levels of C-reactive protein (CRP), produced by the liver and not at the lesion site, correlate with the degree of atherosclerosis.

Electron-beam computed tomography best for evaluating adults with congenital defects in the heart arteries

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for identifying which adult patients face the greatest risk of sudden death from congenital abnormalities in the arteries supplying blood to the heart, according to a study in the September 2005 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

Scientists have identified the first genetic mutations that cause the aorta to widen, tear and rupture

Finding biological markers that flag aneurysm, a bulging of the aorta that leads to dissection, a lengthwise separation of tissues in the artery wall, is critically important for early diagnosis.

Study shows mutation in NOTCH1 gene causes aortic valve disease

By studying five generations of a Dallas family, UT Southwestern Medical Center researchers have discovered that a mutation in a key gene causes aortic valve disease, a common heart birth defect as well as a major contributor to adult heart disease.

White blood cell called a neutrophil appears to be crucial to abdominal aortic aneurysm formation

Each year, 200,000 Americans find out that the largest blood vessel in their body, the aorta, may burst open at any time. About 20,000 die suddenly from such a rupture. And another 36,000 have surgery to repair or replace the swelling section of aorta before time runs out.

Aortic disease difficult to diagnose

Aortic disease kills nearly 15,000 people in the United States each year, but the rarity and complexity of this deadly disorder make accurately diagnosing it difficult for doctors in the health-care trenches, University of Florida researchers have found.

Direct link between inefficient metabolism and atherosclerosis

An experiment that turned out very differently than expected led scientists at Washington University School of Medicine in St. Louis to the first direct link between inefficient metabolism and atherosclerosis.

Routinely reformatting computed tomography (CT) scans to view organs from several different directions may help radiologists improve diagnosis

"You can see things in one view that you might miss in another," said Craig Barnes, M.D., section head of pediatric radiology at Wake Forest Baptist's Brenner Children's Hospital. "It costs no more as relates to scan time or radiation exposure, and we believe it provides added value in diagnosis."

Cocaine use increases the risk of coronary aneurysms

Researchers in Minnesota say that cocaine users may be putting themselves at risk of coronary aneurysms, a ballooning of the walls of coronary arteries, which is potentially fatal.

Australian-designed heart pump gives new hope to heart patients

A 56-year-old New Zealand man, a heart failure patient, is recovering in hospital after world-first surgery to implant an Australian-designed device which helps the heart pump blood.

Risk scores identify young people with hardened arteries

Armed with more knowledge about what cardiovascular disease looks like in people ages 15 to 34, co-authors from the University of Texas Health Science Center, the Southwest Foundation for Biomedical Research and institutions in Delaware, New York, Pennsylvania and Louisiana will report...

Risk scores may identify young individuals with atherosclerosis

Young people with atherosclerotic lesions may be identified by a risk score calculated from coronary heart disease factors like obesity, sex, age, cholesterol, and smoking, according to an article in the April 25 issue of Archives of Internal Medicine.

Simvastatin linked to protection against endothelial dysfunction in diabetic rats

Almost two years ago, the diabetes arm of the Heart Protection Study, the largest-ever study using a cholesterol-lowering medication, found that diabetics who took a daily dose of the statin drug simvastatin over five years reduced the risk of a first nonlethal heart attack by 37 percent and risk of a first nonfatal or fatal stroke by 24 percent, regardless of their cholesterol or glucose levels.

Treatment of cardiac lesions without anaesthesic

Navarre University Hospital has introduced a novel technique for the treatment of congenital heart defects and involving the percutaneous closure of the patent foramen ovale (PFO) with monitoring through intracavernous ecography.

Seniors with giant cell arteritis are twice as likely to have a heart attack or stroke

Seniors with giant cell arteritis – a chronic inflammatory condition of medium and large arteries – are twice as likely to have a heart attack or stroke compared to adults without this condition, says new University of Toronto research.

Clinical trial of newest technology to treat thoracic aortic aneurysms

A clinical trial is underway at the Hospital of the University of Pennsylvania (HUP) to study the safety and effectiveness of an endovascular medical device to treat life-threatening thoracic aortic aneurysms. Ronald Fairman, MD, Chief of Vascular Surgery at HUP, is leading the study at Penn and is one of 35 principal investigators in North America to participate in this landmark trial.

Physical traits, genetic test help with early diagnosis of aneurysm syndrome

A research team led by Johns Hopkins doctors has defined the physical traits and genetic basis of a new aortic aneurysm syndrome that is extremely aggressive and can cause death in early childhood. Early diagnosis of the syndrome and rapid surgical repair of the swollen aorta can save lives, the researchers report in the Jan. 30 advance online section of Nature Genetics.

Smoking and coffee combined have a greater harmful effect on arteries and blood flow

Smoking and coffee often go together. But the combination appears to have a harmful effect on arteries and blood flow that is greater than would be expected from simply combining the effects of each practice.
