By Megan Rauscher NEW YORK (Reuters Health) - Making regular visits to the dentist not only protects the teeth, it also may protect the carotid arteries -- the main blood vessels leading to the brain.
Compared to whites with type 2 diabetes, blacks with type 2 diabetes suffer more heart attacks, strokes, and end-stage renal disease, but African Americans appear to have significantly lower rates of clinical coronary artery disease than whites.
Over time, veins removed from the legs (saphenous veins) and attached to the heart to replace clogged coronary arteries tend to resemble old, sluggish drain pipes. In fact, within five to 10 years of coronary artery bypass surgery, half of all vein grafts become diseased to the point of requiring re-intervention â€“ either repeat open-heart surgery or balloon angioplasty with the insertion of a stent.
In a surprising outcome, investigators at Wake Forest University Baptist Medical Center found that diabetic black men have dramatically lower amounts of atherosclerosis, or hardening of the arteries, than diabetic white men.
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 paper by Sun et al., "C-reactive protein in atherosclerotic lesions: its origin and pathophysiological significance," appears in the October issue of The American Journal of Pathology and is accompanied by a commentary.
Because atherosclerotic plaque typically builds up without symptoms and leads to more than 1 million deaths in America each year, the search is on to develop early detection devices that will enable physicians to offer treatment before the disease progresses to advanced stages.
In a presentation today at the Conference on Lasers and Electro-Optics (CLEO), researchers from Cedars-Sinai Medical Center's Biophotonics Research and Technology Development Laboratory described recent progress on a device that stimulates, collects and measures light emissions from body tissues to diagnose critical atherosclerotic plaques (vulnerable plaques) and aggressive brain tumors.
Background: C-reactive protein (CRP), which has been suggested to directly enhance inflammation in plaques, is rapidly synthesized and secreted in the liver 6 h after an acute inflammatory stimulus.
