American Heart Association says Institute of Medicine (IOM) report an incomplete review of Sodium’s Impact

May 19, 2013 |

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

May 13, 2013 |

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

April 30, 2013 |

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»

American Heart Association says drinking cup of beetroot juice daily may help lower blood pressure

April 18, 2013 |

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.

American Heart Association says eating more fiber may lower risk of first-time stroke

April 11, 2013 |

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

February 7, 2013 |

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»

American Heart Association reports Too much Salt may damage Blood Vessels and lead to High Blood Pressure

June 23, 2012 |

Eating a high-salt diet for several years is associated with markers of blood vessel damage

Dallas, TX – Eating a high-salt diet for several years may damage blood vessels — increasing your risk of developing high blood pressure, according to research reported in the American Heart Association journal Circulation.

People with this type of blood vessel damage who eat a high-salt diet are more likely to develop hypertension, or high blood pressure . This research hints at the presence of a “sodium amplification loop” in which eating too much salt for a long time damages blood vessels, leading to a greater chance of developing high blood pressure if the high-salt diet is continued. «Read the rest of this article»

American Heart Association states No proof that Gum Disease causes Heart Disease or Stroke

April 21, 2012 |

Dallas, TX – Despite popular belief, gum disease hasn’t been proven to cause atherosclerotic heart disease or stroke, and treating gum disease hasn’t been proven to prevent heart disease or stroke, according to a new scientific statement published in Circulation, an American Heart Association journal.

Keeping teeth and gums healthy is important for your overall health. However, an American Heart Association expert committee — made up of cardiologists, dentists and infectious diseases specialists — found no conclusive scientific evidence that gum disease, also known as periodontal disease, causes or increases the rates of cardiovascular diseases. «Read the rest of this article»

American Heart Association reports Patients often stop taking heart drugs during Medicare coverage gaps

April 20, 2012 |

Dallas, TX – Patients who paid for heart medications solely through Medicare were 57 percent more likely to not take them during coverage gaps compared to those who had a Part D low-income subsidy or additional insurance, according to research published in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.

Neither group was more likely to switch to other drugs during coverage gaps. «Read the rest of this article»

American Heart Association reports Long-time diabetics have increased Risk of Stroke

March 1, 2012 |

Dallas, TX – The longer you have diabetes, the higher your risk for stroke, according to a study in Stroke, an American Heart Association journal.

In the study, diabetes increased stroke risk 3 percent each year and tripled the risk for people who had diabetes for 10 years or more, compared to people without diabetes.

“The findings emphasize the chronic nature of diabetes and the fact that it damages the blood vessels over time,” said Mitchell S. V. Elkind, M.D., M.S., the study’s senior author and associate chairman of neurology for clinical research and training at Columbia University Medical Center in New York City. «Read the rest of this article»
