Amputations Due to Poor Blood Flow More Likely in Certain Groups

Posted 19 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

Whistle … and Walk … While You Work

Posted 8 Oct 2015 by Drugs.com

THURSDAY, Oct. 8, 2015 – If you have to sit almost all day while you work, take a short walk whenever you can. Why? Researchers report that even a 10-minute stroll can restore blood flow to legs affected by prolonged sitting. "Although the size of our sample was small, the effects and results we found were still profound," said study first author Robert Restaino, a doctoral student at the University of Missouri, in Columbia, Mo. The findings were published recently in the journal Experimental Physiology. "The obvious take-home is that uninterrupted sitting and inactivity leads to microvascular dysfunction, and therefore is unhealthy," said Dr. William Gray, director of endovascular services at New York-Presbyterian Hospital-Columbia University Medical Center, in New York City. Gray noted that sitting for a long time has previously been linked to heart disease. Restaino said the goal of ... Read more

At-Home Walks Help Those With Clogged Leg Arteries Stay Mobile

Posted 20 May 2015 by Drugs.com

WEDNESDAY, May 20, 2015 – Support groups that encourage walking exercises at home can improve the mobility of people with clogged leg arteries, a new study finds. Clogged leg arteries – called peripheral artery disease – can cause pain and fatigue while walking. This often limits mobility, which is crucial for independent living, doing daily tasks and socializing, the study authors explained. "Patients should understand that home-based exercise can help prevent mobility loss, and health care providers should recognize that this kind of exercise can be beneficial for their patients with peripheral artery disease," said study lead author Dr. Mary McDermott, a professor at Northwestern University Feinberg School of Medicine in Chicago. Research has shown that supervised treadmill workouts improve walking ability among people with peripheral artery disease, but most insurers don't pay ... Read more
