Blood Vessel News and Research

RSS

Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.

Scientists show that endothelial cells give rise to blood stem cells

Stem cell researchers at UCLA have proven definitively that blood stem cells are made during mid-gestational embryonic development by endothelial cells, the cells that line the inside of blood vessels.

ACE inhibitor calcium channel blocker combo drug shown to reduces heart attacks

While doctors are urged to start with a diuretic-based strategy to control patients' high blood pressure, an international blood pressure study shows a different single-pill drug combination is more effective at preventing heart-related events such as heart attacks and strokes.

Portable eight-slice CT in ER increases chance of stroke survival and recovery

New research has found that the availability of a portable eight-slice computed tomography (CT) scanner in an emergency room can significantly increase the number of stroke victims who receive a potentially life-saving treatment.

More evidence on why the Mediterranean diet is good for heart

Researchers have discovered one potential mechanism by which briefly cutting off, then restoring, blood flow to arteries prior to a heart attack lessens the damage caused, according to a study published today in the journal Cardiovascular Research.

Exercise helps blood flow in senior brains

Older adults who exercise regularly show increased cerebral blood flow and a greater number of small blood vessels in the brain, according to findings presented today at the annual meeting of the Radiological Society of North America (RSNA).

Multitasking proteins driving cell behavior

A study describing how cells within blood vessel walls move en masse overturns an assumption common in the age of genomics - that the proteins driving cell behavior are doing so much multitasking that it would be near impossible to group them according to a few discrete functions.

Novel target for therapeutics against Staphylococcus aureus

Researchers at the Texas A&M Health Science Center Institute of Biosciences and Technology, and the University of Edinburgh have uncovered how a bacterial pathogen interacts with the blood coagulation protein fibrinogen to cause methicillin-resistant Staphylococcus aureus (MRSA) infections, a finding that could aid in developing therapeutics against the potentially deadly disease.

Advanced CT scans 100 percent accurate in checking for clogged arteries

In a development that researchers say is likely to quell concerns about the value of costly computed tomography (CT) scans to diagnose coronary artery blockages, an international team led by researchers at Johns Hopkins reports solid evidence that the newer, more powerful 64-CT scans can easily and correctly identify people with major blood vessel disease and is nearly as accurate as invasive coronary angiography.

Mechanisms of cardiovascular disease and cancer give clues to new therapies

Cardiovascular conditions leading to heart attacks and strokes are treated quite separately from common cancers of the prostate, breast or lung, but now turn out to involve some of the same critical mechanisms at the molecular level.

Angioplasty safer in community hospitals when team has more experience

Heart experts at Johns Hopkins have evidence that life-saving coronary angioplasty at community hospitals is safer when physicians and hospital staff have more experience with the procedure.

Neck arteries of obese children and teens look more like those of 45-year-olds

Researchers used ultrasound to measure the thickness of the inner walls of the neck (carotid) arteries that supply blood to the brain. Increasing carotid artery intima-media thickness (CIMT) indicates the fatty buildup of plaque within arteries feeding the heart muscle and the brain, which can lead to heart attack or stroke.

Nanomatrix stent coating designed to mimic natural endothelium

A nanomatrix for stent coating designed at the University of Alabama at Birmingham (UAB) mimics natural endothelium, the substance that lines blood vessels, and promises the potential to prevent post-operative tissue scaring along the blood vessel wall, greatly reducing the possibility of future thrombosis, or blockage at the stent site.

Joyful music has a healthy effect on blood vessel function

Listening to your favorite music may be good for your cardiovascular system.

Medicine, math and engineering combine to reveal how sepsis and less severe infections occur

It's a leading cause of death, but no one knows for sure how and why it happens. It's a major source of health care costs, adding days or weeks to the hospital stays and lost work time of millions of people. But no one fully understands how best to fight it.

Drug-eluting better than bare metal stents in diabetics

Drug-eluting stents reduced the risk of revascularization, heart attack and death in diabetics as compared with bare-metal stents in the largest observational comparison, researchers reported at the American Heart Association's Scientific Sessions 2008.

New blood test identifies sickest heart failure patients in ER

A new blood test identifies the sickest heart failure patients better than tests now used in emergency departments, researchers reported at the American Heart Association's Scientific Sessions 2008. Results of the Mid-Regional pro-Adrenomedullin (proADM) versus BNP and NTproBNP as Prognosticator in Heart Failure Patients: Results of the BACH Multinational Trial were presented as a late-breaking clinical trial.

Exercise training safe in heart failure patients - offer clinical benefit

Exercise training is safe in heart failure patients, does not significantly reduce hospitalization or death, but is associated with several improved clinical outcomes, even in those already receiving optimal medical care, researchers reported at the American Heart Association's Scientific Sessions 2008. The Heart Failure and A Controlled Trial Investigating Outcomes of Exercise Training (HF-ACTION) was presented as a late-breaking clinical trial.

Stem cells from umbilical cord blood may help build new heart valves

Children with heart defects may someday receive perfectly-matched new heart valves built using stem cells from their umbilical cord blood, according to research presented at the American Heart Association's Scientific Sessions 2008.

Daily rhythms in endothelial cells may explain why heart attacks occur most often in early morning hours

It's not just the stress of going to work. Daily rhythms in the activity of cells that line blood vessels may help explain why heart attacks and strokes occur most often in early morning hours, researchers from Emory University School of Medicine have found.

Chaotic vasculature hinders tumor growth

Dense networks of blood vessels thought to spur cancer's growth could actually hinder rather than promote tumor progression, according to a new study at the University of California, San Diego.
