Researchers find low magnesium levels make vitamin D ineffective

A review published in The Journal of the American Osteopathic Association found Vitamin D can't be metabolized without sufficient magnesium levels, meaning Vitamin D remains stored and inactive for as many as 50 percent of Americans.

More TV viewing linked to higher risk of blood clots in veins

A study that followed more than 15,000 people has found that those who reported watching television the most often had the greatest risk for blood clots in their veins compared with those who infrequently or never watched television.

What is sclerotherapy?

Sclerotherapy is a medical procedure whereby a chemical, the sclerosant, is injected into a vein to entirely obliterate it. The sclerosant damages the innermost lining of the vessel, resulting in a clot that blocks the blood circulation in the vein beyond. Veins carry unoxygenated blood from the peripheral tissues back to the heart

LDL cholesterol found to be the main modifiable predictor of atherosclerosis in individuals with no risk factor

A study that followed more than 15,000 people has found that those who reported watching television the most often had the greatest risk for blood clots in their veins compared with those who infrequently or never watched television.

Study links common male medical condition and vascular disease

Men with varicoceles appear to be more likely to develop cardiovascular disease and diabetes than those without the condition, according to a study published in Andrology.1

Mental stress-induced constricted blood vessels more likely in women

In women with heart disease, constriction of peripheral vessels during mental stress affects the heart circulation more than men's, potentially raising women's risk of heart-related events and death, according to new research in Arteriosclerosis, Thrombosis and Vascular Biology, an American Heart Association journal.

Five vascular diseases linked to one common genetic variant

Genome-wide association studies have implicated a common genetic variant in chromosome 6p24 in coronary artery disease, as well as four other vascular diseases: migraine headache, cervical artery dissection, fibromuscular dysplasia, and hypertension. However, it has not been clear how this polymorphism affects the risk for so many diseases. Researchers show how this DNA variant enhances the activity of a gene called endothelin-1, which is known to promote vasoconstriction and hardening of the arteries.

Screening for vascular disease saves one life for every 169 patients assessed

A novel screening program for vascular disease saves one life for every 169 men assessed, according to new research. The combined screening for abdominal aortic aneurysm, peripheral artery disease, and hypertension gained more living years for lower costs than European cancer screening programs.

Novel PET tracer detects small blood clots

Blood clots in veins and arteries can lead to heart attack, stroke, and pulmonary embolism, which are major causes of mortality. Now researchers show that targeting GPIIb/IIIa receptors, the key receptor involved in platelet clumping, with a fluorine-18 labeled ligand is a promising approach for diagnostic imaging.

Midlife cardiovascular risk factors may increase chances of dementia

A large, long-term study suggests that middle aged Americans who have vascular health risk factors, including diabetes, high blood pressure and smoking, have a greater chance of suffering from dementia later in life.
