In an article published in the peer-reviewed SPIE publication Journal of Biomedical Optics (JBO), 'Frequency-domain differential photoacoustic radar: theory and validation for ultra-sensitive atherosclerotic plaque imaging,' researchers demonstrate a new imaging modality that successfully identifies the presence of cholesterol in the arterial plaque.
In the first Mendelian randomization study to look at this, researchers have found evidence that excess weight and body fat cause a range of heart and blood vessel diseases (rather than just being associated with it). The study is published in the European Heart Journal.
A new study has found a high incidence of headaches in pediatric stroke survivors and identified a possible association between post-stroke headache and stroke recurrence.
Vitamin D and estrogen have already shown well-documented results in improving bone health in women. A new study from China suggests that this same combination could help prevent metabolic syndrome, a constellation of conditions that increases the risk of heart disease, stroke, and diabetes in postmenopausal women. Results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
Stroke, one of the leading causes of death worldwide, is normally caused by poor blood flow to the brain, or cerebral ischemia. This must be diagnosed within the first few hours of the stroke for treatment to be effective. Researchers have developed a device that uses near-infrared light to monitor blood flow. The hybrid instrument, which relies on the combination of two light measurement techniques, could be used to quickly and noninvasively diagnose cerebral ischemia.
A team of UK scientists have identified the mechanism behind hardening of the arteries, and shown in animal studies that a generic medication normally used to treat acne could be an effective treatment for the condition.
When prescribed the anticoagulant drug warfarin, many patients are told to limit foods rich in vitamin K, such as green vegetables. The results of a new clinical trial call that advice into question and suggest patients on warfarin actually benefit from increasing their vitamin K intake -- as long as they keep their intake levels consistent.
Researchers have discovered what happens in the brain as people learn how to perform tasks, which could lead to improved lives for people with brain injuries. The study, led by researchers from the University of Pittsburgh and Carnegie Mellon University, revealed that new neural activity patterns emerge with long-term learning and established a causal link between these patterns and new behavioral abilities.
Preliminary findings from a new study reveal that inadequate fruit and vegetable consumption may account for millions of deaths from heart disease and strokes each year. The study estimated that roughly 1 in 7 cardiovascular deaths could be attributed to not eating enough fruit and 1 in 12 cardiovascular deaths could be attributed to not eating enough vegetables.
Previous research indicates that gallstones are linked with an increased risk of stroke. A new Journal of Gastroenterology and Hepatology study found that gall bladder removal may help lower this risk.
