Amputations Due to Poor Blood Flow More Likely in Certain Groups

Posted 18 Nov 2016 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

After Heart Attack, New Threat: Heart Failure

Posted 24 May 2016 by Drugs.com

TUESDAY, May 24, 2016 – Risk of heart failure appears high within a few years of a first heart attack, a new study finds. "Heart failure is a major medical problem with a high chance of hospitalization and death," said study author Dr. Johannes Gho, a cardiology resident at the University Medical Center Utrecht in the Netherlands. Heart failure means the heart can't pump blood efficiently enough to meet the body's demands. Improved heart attack treatment has led to higher survival rates, leaving more patients susceptible to later heart failure, Gho said in a European Society of Cardiology news release. For the study, researchers analyzed data from nearly 25,000 people in the United Kingdom who suffered a first heart attack. Nearly 25 percent of these patients developed heart failure within four years, the investigators found. Certain risk factors increased the risk of heart failure ... Read more

Statins Might Protect People With Narrowed Leg Arteries

Posted 7 May 2016 by Drugs.com

FRIDAY, May 6, 2016 – Cholesterol-lowering statins may spare people with narrowed leg arteries from the possibility of amputation and even death, a new study suggests. The higher the dose of these drugs, the lower the risk of both outcomes, the researchers found. "PAD, a narrowing of the peripheral arteries to the legs, stomach, arms and head, is the next cardiovascular epidemic," said study author Dr. Shipra Arya. She is an assistant professor in the division of vascular surgery at Emory University School of Medicine in Atlanta. For the study, the researchers analyzed health information on more than 200,000 veterans with peripheral artery disease (PAD) from the Veterans Affairs' database. They identified those who were taking statins around the time they were diagnosed with PAD. The researchers also recorded the veterans' dosage of these drugs. During an average follow-up period of ... Read more

Poor Leg Circulation Hits Women With Kidney Disease Earlier Than Men

Posted 23 Feb 2016 by Drugs.com

TUESDAY, Feb. 23, 2016 – Compared to men, women under the age of 70 who have kidney disease are at higher odds for peripheral arterial disease (PAD), an often disabling impairment of blood flow in the legs. That's the finding from a new study of almost 3,200 people with chronic kidney disease. Researchers led by Dr. Grace Wang, of the Hospital of the University of Pennsylvania in Philadelphia, found that women under 70 with kidney disease had a 53 percent higher risk of PAD compared to their male peers. However, after age 70 the difference between the sexes evened out, the researchers noted. Why would PAD affect women earlier? According to the study authors, "females are known to have smaller diameter vessels compared to men." That could mean that, given similar amounts of plaque buildup in vessels, women's might close off earlier than men's. The findings show that women with kidney ... 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

Strengthening Hip Muscles May Ease Calf Pain From Blood Vessel Disease

Posted 7 May 2015 by Drugs.com

THURSDAY, May 7, 2015 – Exercises to strengthen the hips may ease calf pain for people with peripheral artery disease (PAD), a new study suggests. The disease causes the arteries in the legs and other parts of the body to narrow, restricting blood flow. This can lead to changes in skin color, sores, pain and trouble walking. Japanese researchers found that people with clogged leg arteries use their calf muscles more while walking since certain muscles in their hips are weaker. By strengthening their hip muscles, they may be able to walk longer without pain, the study showed. "PAD patients should ask for an expert, such as a physical therapist, to evaluate their gait and the strength of their hip flexors and other muscles. Based on the evaluation, a combination of muscle training and walking exercise may increase how far they can walk and reduce their calf pain during walking," study ... Read more

Aspirin as Good as Plavix for Poor Leg Circulation: Study

Posted 21 Feb 2012 by Drugs.com

TUESDAY, Feb. 21 – Aspirin works as well as Plavix in patients with blocked leg arteries, a new European study finds. People with the condition, called peripheral artery disease, often suffer from intermittent claudication, which is pain while walking because of decreased blood supply to the legs. Animal experiments had suggested that aspirin might block the growth of blood vessels that bypass blockages and help get more blood to leg tissue, the Swiss and German researchers said. "Once again, we have shown that what happens in animals doesn't translate to humans," said Dr. Juan Zambrano, an assistant professor of cardiovascular medicine, coronary/endovascular and stem cell therapies at the University of Miami Miller School of Medicine. Patients suffering from peripheral artery disease are also at increased risk of heart attack and stroke from blood clots traveling from the legs to the ... Read more
