New technology gives unprecedented look inside capillaries
More than 40 billion capillaries—tiny, hair-like blood vessels—are tasked with carrying oxygen and nutrients to the far reaches of the human body. But despite their sheer number and monumental importance to basic functions and metabolism, not much is known about their inner workings.
Blood test for specific metabolites could reveal blocked arteries
A pilot project suggests that in the near future, a blood test could show whether arteries carrying blood to the heart are narrow or blocked, a risk factor for heart disease.
Cancer increases the risk of heart attacks, strokes and vascular occlusions
It is well known that pre-existing cancer is a significant risk factor for venous thrombosis. What was hitherto unclear was whether cancer also has a negative impact upon the risk of heart attacks, strokes or occlusions of peripheral arteries. A study conducted at MedUni Vienna's Division of Hematology and Hemastasology within its Department of Medicine I and recently published in leading journal Haematologica, shows for the first time that the risk of these arterial thromboses and their consequences is also higher in patients with cancer.
Tobacco aside, e-cigarette flavorings may harm blood vessels
Flavor additives used in electronic cigarettes and related tobacco products could impair blood vessel function and may be an early indicator of heart damage, according to new laboratory research in Arteriosclerosis, Thrombosis and Vascular Biology, an American Heart Association journal.
The influence of circadian rhythms on atherosclerosis
The internal clock controls all vital functions in the body. Body temperature as well as blood pressure or the release of certain enzymes are subject to oscillations throughout the day, the so-called circadian rhythm. For the first time, a team around Professor Oliver Söhnlein has now shown the influence of circadian rhythms on atherosclerosis—a vascular disease that ultimately can lead to heart attacks and strokes. His study, recently published in the scientific journal Cell Metabolism, could be crucial for the improvement of therapeutic approaches.
Study suggests new strategy against vascular disease in diabetes
Recent findings suggest a novel approach for protecting people with diabetes from their higher risk of advanced blood vessel disease, which sets the stage for early heart attacks and strokes. Cardiovascular problems from atherosclerosis - plaque-like lesions forming in artery walls - are the major cause of death in people with type 2 diabetes and metabolic syndrome.
Stem cells show long-term success in treating severe peripheral arterial disease
A long-term study of patients who received stem cells to treat angiitis-induced critical limb ischemia (AICLI) shows the cells to be both safe and effective. The study, published in STEM CELLS Translational Medicine (SCTM), could lead to an option for those who suffer from this serious form of peripheral arterial disease (PAD).
Vascular problems associated with symptoms of menopause and quality of life measures
A new study shows that more frequent and severe menopausal symptoms such as hot flashes, sleep disturbance, loss of sexual interest, weight gain and other quality of life measures, were associated with markers of vascular aging, according to researchers at the University of Colorado Anschutz Medical Campus.
