High blood levels of these DNA particles may eventually help identify patients at risk for further serious heart problems.
Dallas, TX – DNA fragments in your blood may someday help doctors quickly learn if chest pain means you have narrowed heart arteries, according to a new study published in the American Heart Association journal Arteriosclerosis, Thrombosis, and Vascular Biology.
The study involved 282 patients, ages 34 to 83, who reported chest pain and were suspected of having coronary artery disease. Researchers used computed tomography imaging to look for hardened, or calcified, buildup in the blood vessels that supply the heart. Blood samples also were tested for bits of genetic material. Release of small DNA particles in the blood occurs during chronic inflammatory conditions such as coronary artery disease. «Read the rest of this article»
Quality improvement programs addressing stroke care should be organized in all stroke centers.
Dallas, TX – People having an ischemic stroke should receive clot-dissolving therapy – if appropriate — within 60 minutes of arriving at the hospital, according to new American Stroke Association guidelines published in the American Heart Association journal Stroke.
Ischemic stroke, which accounts for nine in 10 strokes, is caused by a blood clot in the arteries leading to the brain. Calling 9-1-1 immediately after recognizing any of the warning signs of stroke — and getting to a stroke center as fast as possible — are still the most important steps for optimal stroke care. «Read the rest of this article»
Blueberries and strawberries contain high levels of compounds that have cardiovascular benefits.
Dallas, TX – Eating three or more servings of blueberries and strawberries per week may help women reduce their risk of a heart attack by as much as one-third, researchers reported in Circulation: Journal of the American Heart Association.
Blueberries and strawberries contain high levels of naturally occurring compounds called dietary flavonoids, also found in grapes and wine, blackberries, eggplant, and other fruits and vegetables. A specific sub-class of flavonoids, called anthocyanins, may help dilate arteries, counter the buildup of plaque and provide other cardiovascular benefits, according to the study. «Read the rest of this article»

Dallas, TX – Directing short bursts of radio waves at nerves surrounding the kidneys lowered blood pressure for at least six months and up to one year among patients with hypertension External link that persists regardless of taking multiple medications to control it, according to a new study published in the American Heart Association journal, Circulation.
The findings could have significant public health implications in the treatment of resistant hypertension, a major risk factor for heart attack and stroke, said Murray Esler, M.B.B.S., Ph.D., Professor and Senior Director of the Baker IDI Heart and Diabetes Institute in Melbourne, Australia. «Read the rest of this article»
