Dallas, TX – The caffeine in a cup of coffee might help your small blood vessels work better, according to research presented at the American Heart Association’s Scientific Sessions 2013.
A study of 27 healthy adults showed – for the first time – that drinking a cup of caffeinated coffee significantly improved blood flow in a finger, which is a measure of how well the inner lining of the body’s smaller blood vessels work.
Dallas, TX – Children’s congenital heart defects may be associated with their mothers’ exposure to specific mixtures of environmental toxins during pregnancy, according to research presented at the American Heart Association’s Scientific Sessions 2013.
Congenital heart defects occur when the heart or blood vessels near the heart don’t develop normally before birth. Defects may be caused by chromosomal abnormalities, but the cause is unknown in most cases. «Read the rest of this article»
Dallas, TX – A new type of defibrillator implanted under the skin can detect dangerously abnormal heart rhythms and deliver shocks to restore a normal heartbeat without wires touching the heart, according to research in the American Heart Association journal, Circulation.
The subcutaneous implantable cardiac defibrillator (S-ICD®System) includes a lead placed under the skin along the left side of the breast bone. Traditional implantable cardiac defibrillators (ICDs) include electrical conducting wires inserted into blood vessels that touch the heart.
American Heart Association says DNA particles in the Blood may help speed detection of Coronary Artery Disease
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»
American Heart Association says Institute of Medicine (IOM) report an incomplete review of Sodium’s Impact
Dallas, TX – The American Heart Association says a new report from the Institute of Medicine (IOM) — Sodium Intake in Populations: Assessment of Evidence — is incomplete in its assessment of sodium’s impact on health because it does not focus its examinations on scientific evidence that links excess consumption and high blood pressure.
The report found that though reducing sodium intakes from current levels is important, and that there is a positive relationship between higher levels of sodium intake and risk of heart disease, there is not enough evidence to conclude that sodium reduction below 2,300 mg daily leads to less heart disease, stroke and a reduced risk of death.
American Heart Association reports Diet, ‘anti-aging’ supplements may help reverse blood vessel abnormality
Nashville, TN – A diet low in grains, beans and certain vegetables — combined with “anti-aging” supplements — improved blood vessel function, in a study presented at the American Heart Association’s Arteriosclerosis, Thrombosis and Vascular Biology 2013 Scientific Sessions.
The blood vessel abnormality, or endothelial dysfunction, occurs when cells lining the interior wall of blood vessels malfunction. It’s a serious condition that’s often one of the first signs of heart disease. «Read the rest of this article»
American Heart Association reports “Off-the-shelf” artificial blood vessels may reduce dialysis complications
Artificial blood vessels remained durable in an animal trial and show promise for patients with end-stage kidney disease.
Dallas, TX – “Off-the-shelf” blood vessels could one day reduce some complications of dialysis treatment, according to preliminary research presented at the American Heart Association’s Emerging Science Series Webinar.
Scientists bioengineered an artificial blood vessel by seeding human aorta cells onto a biodegradable mesh tube. In the process, a tubular vein develops in two months as the growing cells secrete proteins and the mesh support structure dissolves. The new vessel is then prepped in a way that minimizes chances of an immune reaction in the recipient. «Read the rest of this article»
Increasing intake of foods rich in dietary nitrate may be an affordable and attainable way to manage blood pressure, researchers said.
Dallas, TX – A cup of beetroot juice a day may help reduce your blood pressure, according to a small study in the American Heart Association journal Hypertension.
People with high blood pressure who drank about 8 ounces of beetroot juice experienced a decrease in blood pressure of about 10 mm Hg. But the preliminary findings don’t yet suggest that supplementing your diet with beetroot juice benefits your health, researchers said.
The results reinforce the importance of a diet that includes at least 25 grams of fiber daily.
Dallas, TX - Eating more fiber may decrease your risk of first-time stroke, according to new research in the American Heart Association journal Stroke.
Dietary fiber is the part of the plant that the body doesn’t absorb during digestion. Fiber can be soluble, which means it dissolves in water, or insoluble.
American Heart Association Report shows Traumatic brain injury complications common among U.S. combat soldiers
A transcranial Doppler is a non-invasive, inexpensive and portable way to assess these complications.
Honolulu, HI – U.S. soldiers in combat often suffer constricted blood vessels and increased pressure in the brain — significant complications of traumatic brain injuries, according to research presented at the American Stroke Association’s International Stroke Conference 2013.
“Research shows that traumatic brain injury is a hallmark of recent military conflicts, affecting nearly a third of all wounded soldiers,” said Alexander Razumovsky, Ph.D., lead researcher and director of Sentient NeuroCare Services in Hunt Valley, MD. «Read the rest of this article»
