Atherosclerosis News and Research

RSS

Atherosclerosis is the progressive buildup of plaque - the fatty deposits and other cells - in the inner walls of the arteries. The condition is a consequence of elevated cholesterol and for many it's a silent disease, with no visible signs or symptoms. The disease can begin in early adulthood and continues to progress for the rest of a person's life. Despite the serious nature of atherosclerosis, many people do not understand how it develops and progresses.

Significant step forward in the genome era

In what promises to be a significant step forward in the genome era, the National Human Genome Research Institute (NHGRI) today announced plans to devote a portion of its large-scale sequencing capacity to efforts aimed at identifying the genetic roots of specific diseases that have long eluded gene hunters.

Erectile dysfunction may be a sign that coronary artery disease is developing

"We think that erectile dysfunction represents the 'tip of the iceberg' of a systemic vascular disorder; thus potentially preceding severe cardiovascular events. Erectile dysfunction should be part of a cardiovascular risk assessment.

Cholesterol levels among older adults has declined significantly

The total cholesterol level among older adults has declined significantly, while there has been little change among younger adults, according to a study in the October 12 issue of JAMA: The Journal of the American Medical Association.

Gleevec's uses might expand even further

Gleevec (Imatinib) is a representative of the newest generation of cancer drugs. The substance conveys its potent anti-proliferative effect by selectively supressing the tyrosine kinase pathway. The Giessen lung researchers now issue a first report of this substance as a new target therapy for pulmonary hypertension

Mayo Clinic researchers find earliest sign of nerve change due to diabetes

Mayo Clinic researchers have found that subtle change in nerve conduction is the first reliable sign of nerve complications from diabetes and that this change can be measured long before other symptoms or signs of nerve damage develop.

Flavanols help smokers repair blood vessel function

Phytochemicals known as flavanols, which are found in chocolate, fruits and vegetables, can boost the levels of nitric oxide in the blood of smokers and reverse some of their smoking-related impairment in blood vessel function, according to a new study in the Oct. 4, 2005, issue of the Journal of the American College of Cardiology.

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.

The immune mechanisms of atherosclerosis

Scientists are depicting a novel scheme for atherosclerosis development, suggesting that this pathology might result from an imbalance between pro-inflammatory processes and calming ones.

Farnesyl transferase inhibitors may help chidren with Hutchinson-Gilford progeria syndrome

Johns Hopkins scientists have discovered that a drug currently being tested against cancers might help children with a rare, fatal condition called Hutchinson-Gilford progeria syndrome, which causes rapid, premature aging.

Smoking may increase the risk of developing diabetes

The surprising finding emerged when researchers examined the relationship between smoking and diabetes among participants in a major national study, the Insulin Resistance Atherosclerosis Study (IRAS).

"Designer" rats help show how declining estrogen after menopause can affect hypertension

Scientists at Wake Forest University School of Medicine have created a better research rat – the first to enable them to study how declining estrogen after menopause can affect hypertension, heart failure and kidney damage.

Significant death risk linked to airborne particles

Experts may be significantly underestimating air pollution's role in causing early death, according to a team of American and Canadian researchers, who studied two decades' worth of data on residents of the Los Angeles metro area.

Lowering blood sugar levels could reduce the risk of coronary heart disease

Lowering blood sugar levels could reduce the risk of coronary heart disease in both diabetics and non-diabetics, according to researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions.

Bariatric surgery is a safe option for treating obese patients who have coronary artery disease

The findings are important because coronary artery disease patients can see a significant benefit with a successful procedure. The resulting weight loss is also followed by an improvement in blood pressure, cholesterol, blood sugar and sleep apnea, all factors linked to coronary artery disease.

Metabolic Syndrome, a map of the cardiovascular damage

The metabolic syndrome (MS) is a cluster of metabolic abnormalities with abdominal obesity (increased waist circumference) at its centre. Although all forms of obesity have a negative impact on human health, metabolic syndrome describes a set of particularly adverse biochemical changes accompanying (abdominal) obesity.

Sports and exercise - in addition to preventing obesity and diabetes - directly improve vascular function and reduce atherosclerosis

When asked about his personal recipe for old age, Winston Churchill used to answer: "First of all: No sports." While being a visionary figure in world politics researchers in cardiovascular exercise science today would unanimously reply to his medical hypothesis: "Sorry, you are wrong."

Legs For Life free national screening program can save legs

The screening is essential for diabetics in order to prevent amputation, heart attack and stroke, because one-third have PAD, but most do not present classic symptoms.

Nitric oxide synthase plays a role in peripheral vascular disease

The enzyme nitric oxide synthase plays a role in peripheral vascular disease, a common disease that impairs the mobility of 25 percent of people over the age of 50, according to a Yale study in the Proceedings of the National Academy of Sciences (PNAS).

MRI helps map smallest deformations inside hearts

Using magnetic resonance imaging technology, or MRI, to tag the work of millions of individual strands of heart muscle fibers, researchers at Johns Hopkins have successfully mapped the smallest deformations inside the beating hearts of 441 middle-aged and elderly men and women who have either silently developed heart disease or remained healthy.

New study shows even non-prescription painkillers raise blood pressure in women

According to a new U.S. study women who take higher doses of common, over-the-counter painkillers, such as Ibuprofen and even Tylenol, have higher blood pressure than women who do not.
