Digestive Byproduct Tied to Meat Raises Risks for Some Heart Patients

Posted 4 days ago by

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

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

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

Restoring Blood Flow Beats Exercise for Poor Leg Circulation

Posted 5 May 2016 by

THURSDAY, May 5, 2016 – For people with poor circulation in their leg arteries, a medical procedure to restore blood flow may have greater benefits than exercise, preliminary research suggests. People with peripheral artery disease (PAD) experience pain and fatigue while walking. These symptoms develop because poor circulation in the arteries that supply blood to the limbs causes damage and scarring in the muscles, the researchers explained. There is currently no way to reverse the scarring associated with PAD. But a procedure to reopen or bypass blockages in the blood vessels and restore blood flow to the limbs – also known as revascularization – prevents it from getting worse, the researchers said. For the study, the researchers analyzed levels of a protein, called TGF-Beta1, that triggers scarring in patients with severe PAD. The investigators also measured levels of collagen, ... Read more

Poor Leg Circulation Hits Women With Kidney Disease Earlier Than Men

Posted 23 Feb 2016 by

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

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

Medical Costs Soar for Smokers Who Develop Artery Disease

Posted 28 Sep 2015 by

MONDAY, Sept. 28, 2015 – Smoking significantly increases medical costs among people with peripheral artery disease (PAD), a new study suggests. PAD is a condition in which a buildup of plaque in the arteries restricts blood flow to the legs and feet. Researchers analyzed 2011 health insurance claims data from more than 22,000 PAD patients in Minnesota, and found that annual per-patient health care costs were $18,000 higher among smokers than among nonsmokers. The hospitalization rate was 49 percent among smokers, 35 percent higher than among nonsmokers, the findings showed. Smokers were more likely to be hospitalized for leg problems, heart attack and heart disease than nonsmokers, the University of Minnesota Medical School researchers found. Sue Duval, an associate professor of cardiology and biostatistics, led the project. The study was published online Sept. 28 in the Journal of the ... Read more

1 in 6 Americans Too Far From Lifesaving Heart Centers

Posted 13 Jul 2015 by

MONDAY, July 13, 2015 – Tens of millions of rural, poor and Hispanic Americans do not have timely access to a lifesaving heart procedure, a new study finds. Researchers analyzed the driving times for 306 million people to reach the closest angioplasty centers across the continental United States. Angioplasty is used to open blocked heart arteries. A catheter is used to insert a deflated balloon into the artery. The balloon is then inflated to open the artery and restore blood flow to the heart. There are more than 1,700 angioplasty centers in the United States, the researchers said. The median time to an angioplasty center was 33 minutes, they found. However, the median travel time for more than 16 percent of the population – about 50 million people – was 81 minutes, according to the study. Results were published July 13 in the journal Health Services Research. It shouldn't take ... Read more

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

Posted 20 May 2015 by

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

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

Leg Artery Procedure May Be Overused in Nursing Homes, Study Finds

Posted 6 Apr 2015 by

MONDAY, April 6, 2015 – Surgery to reopen blocked arteries in the legs of frail nursing home residents rarely gets them back on their feet, a new study shows. In fact, many elderly people who undergo the expensive procedure either lose more physical function or die within a year of the surgery, according to a review of Medicare claims data by researchers from the University of California, San Francisco (UCSF). However, that doesn't prove the surgery is unnecessary in all or even many cases, said senior study author Dr. Emily Finlayson, director of the UCSF Center for Surgery in Older Adults. Blocked blood vessels in a leg can cause extreme and chronic pain, or promote infections or gangrene that can lead to amputation. "This operation can actually make those symptoms better," Finlayson explained. "Even if that patient only has six to eight months to live, this may be an appropriate ... Read more

Imaging Tests May Help Stem Amputations for Circulatory Disorder

Posted 4 Feb 2015 by

WEDNESDAY, Feb. 4, 2015 – Patients with peripheral arterial disease (PAD) who face amputation of a foot or leg can have their limb saved by minimally invasive surgery to improve blood flow, a new study suggests. Among the patients tested and treated in a limb salvage program, amputation rates dropped nearly 80 percent, according to Dr. Julio Sanguily, a vascular surgeon with Martin Health System in Stuart, Fla., who led the study. "A multidisciplinary approach that includes vascular surgeons, with support from podiatry, infectious disease specialists and wound care, can significantly reduce the number of amputations," Sanguily said. The results of his trial were presented Tuesday at the International Symposium on Endovascular Therapy meeting in Hollywood, Fla. Research presented at medical meetings is considered preliminary until published in a peer-reviewed journal. According to ... Read more

Drug-Coated Balloon Catheter Approved

Posted 13 Oct 2014 by

MONDAY, Oct. 13, 2014 – The first drug-coated balloon catheter designed to clear narrowed or blocked arteries in the thigh and knee has been approved by the U.S. Food and Drug Administration. The Lutonix 035 Drug Coated Balloon Percutaneous Transluminal Angioplasty Catheter has a balloon coated with the drug paclitaxel, which may help prevent re-narrowing of the affected artery after the clearing procedure, the FDA said. The device is approved to clear vessels clogged by Peripheral Artery Disease (PAD), which causes hardening and narrowing of the arteries and limits distribution of oxygen-rich blood. Symptoms may include leg pain, skin ulcers or gangrene. The device was evaluated in clinical studies involving more than 500 people. In one study after six months, about 72 percent of those treated with the Lutonix device did not require additional treatment for PAD, compared to nearly ... Read more

Poor More Prone to Leg Circulation Trouble

Posted 14 Jul 2014 by

FRIDAY, July 11, 2014 – People with the lowest incomes may have a higher risk for a circulatory condition called peripheral artery disease (PAD), a new study suggests. People with PAD have narrowing of the arteries that supply blood to the limbs, most often the legs. The condition causes leg pain and is often an indicator of narrowing of the arteries throughout the body. People with PAD have a higher risk for heart disease and stroke. Researchers analyzed data from nearly 6,800 people with PAD who took part in the U.S. National Health and Nutrition Examination Survey from 1999 to 2004. They found that those with low incomes were significantly more likely to have the disease. People with the lowest income levels were more than twice as likely to have PAD as those with the highest income and education levels, according to the study published online recently in the journal Circulation: ...

Could Dark Chocolate Help Ease Poor Leg Circulation?

Posted 3 Jul 2014 by

WEDNESDAY, July 2, 2014 – The antioxidants contained in dark chocolate might help people suffering from reduced blood flow to their legs, researchers from Italy report. In a small study, people with artery problems in their legs walked a little longer and farther right after eating a bar of dark chocolate, the researchers said. Dark chocolate is rich in antioxidants called polyphenols. The researchers believe polyphenols improve blood flow to the legs by affecting biochemicals that prompt arteries to widen. "Our body secretes chemicals that naturally dilate blood vessels in response to certain stimuli, improving the blood flow to certain areas," said Dr. Richard Chazal, vice president of the American College of Cardiology. "Some of the chemicals inside dark chocolate could affect the way these enzymes are metabolized in the body," suggested Chazal, who was not involved with the study. ... Read more
