Amputations Due to Poor Blood Flow More Likely in Certain Groups

Posted 18 days ago by Drugs.com

FRIDAY, Nov. 18, 2016 – Poor and black patients with narrowing of the blood vessels have a higher risk of amputation than other patients, a new study finds. Peripheral artery disease (PAD), as this blood-vessel narrowing is called, develops when fat, cholesterol and other substances accumulate in blood vessels away from the heart and restrict blood flow. It typically occurs in the legs. Besides increasing the risk for heart attack and stroke, untreated peripheral artery disease can lead to tissue death ("gangrene") that results in amputation, the study authors explained. For this study, researchers analyzed data from more than 208,000 U.S. veterans with the disease. The investigators found that black patients had a 43 percent higher risk of amputation than white patients in the same socioeconomic group. And poor patients had a 37 percent increased risk of amputation, regardless of ... Read more

Digestive Byproduct Tied to Meat Raises Risks for Some Heart Patients

Posted 19 Oct 2016 by Drugs.com

WEDNESDAY, Oct. 19, 2016 – People with peripheral artery disease – a narrowing of the arteries in the legs and elsewhere – who eat a lot of red meat and eggs may have increased odds of dying early, a new study suggests. That's because of a digestive byproduct produced by gut bacteria that breaks down eggs, red meat and other meat products found in the traditional Western diet, the researchers said. The byproduct is called trimethylamine N-oxide (TMAO), and the study found that people with peripheral artery disease who also high levels of TMAO had a nearly three times higher risk of dying within five years, compared with those with the lowest levels. "These findings point to the potential for TMAO to help identify high-risk patients who likely need more aggressive and specific dietary and pharmacologic therapy," said lead researcher Dr. W.H. Wilson Tang, a professor in medicine at the ... Read more
