Air Pollution Linked to Increased Stroke Risk, Study Says

Posted 6 Mar 2015 by

FRIDAY, March 6, 2015 – High levels of small-particle air pollution can increase your risk for narrowing of the neck (carotid) arteries, which may raise your risk for stroke, a new study says. Researchers analyzed the results of cardiovascular screening tests from more than 300,000 people in New York, New Jersey and Connecticut. Those who lived in areas with the highest levels of air pollution were 24 percent more likely to have narrowing of the carotid arteries than those in areas with the lowest levels of air pollution. The carotid arteries deliver blood to the brain. The investigators focused on a type of air pollution called fine particulate matter – particles of pollution smaller than 2.5 micrometers in diameter. Fine particulate matter is the most common type of air pollution and comes from sources such as car exhaust and the burning of wood or coal. The study is scheduled for ... Read more

Early Studies See No Heart Risk From Testosterone Therapy

Posted 4 Mar 2015 by

WEDNESDAY, March 4, 2015 – Testosterone therapy doesn't seem to increase a man's risk of heart attack or stroke, a pair of new studies suggests. "Testosterone therapy in any form – gel, pills or injections – does not appear to cause adverse cardiovascular effects," said Dr. Pawan Patel, lead author of one of the studies and an academic physician at Regions Hospital in St. Paul, Minn. The studies are to be presented next week at the American College of Cardiology (ACC) annual meeting, in San Diego. Research presented at medical meetings is typically viewed as preliminary until published in a peer-reviewed journal. The two studies were released a day after the U.S. Food and Drug Administration issued a warning about the overuse of testosterone-boosting drugs by aging baby boomers trying to use hormone therapy to turn back the clock. The FDA will require all prescription testosterone ... Read more

1 in 3 Americans Lives an Hour or More From a Stroke Center

Posted 4 Mar 2015 by

WEDNESDAY, March 4, 2015 – One-third of Americans can't be transported by ambulance to a stroke center within one hour, a new study reports. Even under the best conditions, a large number of Americans would not be able to arrive at a stroke center within an hour because they live too far away, according to the study. "Research has shown that specialized stroke care has the potential to reduce death and disability," wrote study author Dr. Michael Mullen, from the University of Pennsylvania. "Stroke is a time-critical disease. Each second after a stroke begins, brain cells die, so it is critically important that specialized stroke care be rapidly accessible to the population," he explained. Results of the study were published online March 4 in the journal Neurology. Mullen and his colleagues examined data from 2010, when there were 811 primary stroke centers in the United States. ...

Does Long-Term Acetaminophen Use Raise Health Risks?

Posted 3 Mar 2015 by

MONDAY, March 2, 2015 – Acetaminophen may not be as safe as previously thought, with larger doses and long-term use linked to increased risk of health problems, a new report contends. Best known in the United States under the brand name Tylenol, acetaminophen is the most widely used painkiller in the world, the study authors said in background notes. It is the World Health Organization's front-line treatment for pain, and is considered safer than nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen, the researchers said. But a small group of studies has raised questions about acetaminophen's safety if used for a long time and at high doses to treat chronic pain, said lead author Dr. Philip Conaghan, a professor with the Leeds Institute of Rheumatic and Musculoskeletal Medicine in England. Heavy use of acetaminophen is associated with kidney disease and bleeding ... Read more

Long Sleep Time, Higher Stroke Risk?

Posted 25 Feb 2015 by

WEDNESDAY, Feb. 25, 2015 – Adults who sleep more than eight hours a night may face a higher risk of stroke, a new analysis suggests. These so-called "long sleepers" were 46 percent more likely to have a stroke than those who got only six to eight hours of sleep a night, the researchers found. However, the researchers don't know if the long sleep is a cause, consequence or early warning sign of declining brain health. After reviewing previous research on the possible link between sleep and stroke risk, they said they only found an association that they can't explain. The study is published online Feb. 25 in Neurology. "Previous studies have already suggested a possible association between sleep and risk of stroke," said lead researcher Yue Leng, of the University of Cambridge in England. But the new analysis also looked at the relationship between a change in sleeping duration over time ... Read more

Aspirin 'Resistance' May Make for Worse Strokes: Study

Posted 23 Feb 2015 by

MONDAY, Feb. 23, 2015 – People who are "resistant" to aspirin may be at risk for larger, more severe strokes, South Korean researchers report. Doctors often prescribe low-dose aspirin to people at high risk of stroke because the drug helps prevent blood clots. But for about 28 percent of stroke patients in a new study, aspirin didn't keep blood from clotting. And their strokes were worse than strokes suffered by aspirin-users who weren't resistant to the drug. "Aspirin resistance is an important predictor of severe stroke and large stroke size in patients taking aspirin before having a stroke," said lead researcher Dr. Mi Sun Oh, of the department of neurology at Hallym University College of Medicine in Seoul. What causes aspirin resistance isn't known. Other studies have found that between 5 percent and 45 percent of patients have this problem, but doctors do not routinely test for ... Read more

More Evidence That Even 'Moderate' Exercise Helps Women's Hearts

Posted 16 Feb 2015 by

MONDAY, Feb. 16, 2015 – Even a few bouts of moderate exercise each week can cut a middle-aged woman's odds for heart disease, blood clots and stroke, a new study finds. The British study also found that exercising more frequently didn't lead to greater reductions in heart risk. The take-home message, according to study lead author Miranda Armstrong: "To prevent heart disease, stroke and blood clots, women don't have to be super athletes or strenuously exercise daily to experience the benefits of physical activity." In fact, adding lots of extra strenuous exercise may offer "little additional benefit above that from moderately frequent activity," Armstrong said in a news release from the American Heart Association. She is a physical activity epidemiologist at Oxford University in England. The findings are published Feb. 16 in the journal Circulation. In the study, Armstrong's team ... Read more

Kids Living in 'Stroke Belt' Not More Likely to Have Stroke: Study

Posted 12 Feb 2015 by

THURSDAY, Feb. 12, 2015 – Children who live in a region of the United States known as the "stroke belt" are not more likely to be hospitalized for stroke than those who don't live there, a new study finds. Adults in the stroke belt – located in the southeastern United States – are more likely to be hospitalized for stroke and die from it than adults in other parts of the country, researchers say. Previous research has also found that youngsters in the stroke belt may be more likely to die from stroke than other American children. In this study, researchers led by Dr. Judith Lichtman of the Yale School of Public Health in New Haven, Conn., examined data on stroke patients hospitalized across the country between 2006 and 2009. Stroke hospitalization rates for adults in the stroke belt were 32 percent to 52 percent higher than for those in other parts of the country. But, the study ... Read more

Clot-Busting Drug May Be Safe for Those With 'Wake-Up' Strokes

Posted 12 Feb 2015 by

THURSDAY, Feb. 12, 2015 – The clot-busting drug known as tPA appears safe for those who wake up in the morning to find they've had a stroke, a small new study suggests. Many people with these "wake-up strokes" do not receive tPA (tissue plasminogen activator) because of restrictions on its use to within three hours of the start of stroke symptoms. That's because for most patients who realize they have stroke symptoms upon waking, it's unclear just how long ago the stroke occurred. "There is a time limit of three hours [4.5 hours in select patients] to treat people with acute stroke with intravenous tPA, because there is an increased incidence of hemorrhage in patients treated outside the time window," explained one expert, Dr. Rafael Alexander Ortiz. Up till now, "in patients that complain of stroke symptoms at the time of waking up, it has been determined that the risk of treatment ... Read more

Low Vitamin D Levels in Stroke Survivors a Bad Sign, Study Finds

Posted 12 Feb 2015 by

THURSDAY, Feb. 12, 2015 – Low vitamin D levels are linked to an increased risk of suffering a severe stroke and poor health in stroke survivors, new research finds. The study included almost 100 stroke patients who were treated at a U.S. hospital between 2013 and 2014. All had experienced an ischemic stroke, which is a stroke caused by blocked blood flow to the brain. People with low blood levels of vitamin D – less than 30 nanograms per milliliter (ng/mL) – had about two times larger areas of stroke-related dead brain tissue than those with normal vitamin D levels, according to the study. The researchers also found that for each 10 ng/mL reduction in vitamin D level, the odds of a healthy recovery in the three months after stroke fell by about half, regardless of age or initial stroke severity. Although this study found an association between low vitamin D levels and poor stroke ... Read more

Parents of Young Stroke Victims at Risk for PTSD, Researchers Find

Posted 12 Feb 2015 by

THURSDAY, Feb. 12, 2015 – Parents of children who suffer a stroke are at risk for post-traumatic stress disorder (PTSD), a small study suggests. The research included 10 fathers and 23 mothers of children and teens who had suffered a stroke, as well as nine stroke patients between the ages of 7 and 18. The researchers found that 55 percent of the parents met at least one of the PTSD criteria and 24 percent met all the criteria. PTSD was not seen in any of young stroke patients, but 22 percent of them had clinically significant levels of anxiety. "Our concern is that PTSD in parents of a child with stroke or pediatric stroke patients experiencing anxiety may have a harder time complying with therapy, which could affect health outcomes of the child," lead researcher Dr. Laura Lehman, a neurologist at Boston Children's Hospital, said in an American Stroke Association news release.

Motorized Stationary Bike May Help With Stroke Rehabilitation

Posted 12 Feb 2015 by

THURSDAY, Feb. 12, 2015 – Exercising on a motorized stationary bike may help boost stroke patients' brain and motor skills recovery, a small study suggests. The study included 17 stroke survivors, aged 23 to 84, whose stroke occurred six to 12 months before the start of the study. To help them regain the use of their arms, all of the patients took part in repetitive task therapy, such as relearning how to hold a cup or fork, or how to dress themselves. In addition to this, the patients were randomly assigned to one of three groups: exercise on a motorized stationary bike; using a stationary bike without a motor; or no aerobic exercise at all but twice as much upper body repetitive task therapy. All the cycling sessions lasted 45 minutes and were done before the repetitive task therapy for their arms. All three groups did 24 exercise sessions over eight weeks. At the end of that time, ...

Dehydration Linked to Greater Stroke Damage

Posted 12 Feb 2015 by

THURSDAY, Feb. 12, 2015 – People who aren't well-hydrated when they have a stroke are about four times more likely to have a worse outcome than people who've had more fluids, a new study suggests. Researchers found that stroke effects worsened or stayed the same in 42 percent of dehydrated patients after hospitalization for their stroke, compared to 17 percent of hydrated patients. Stroke outcomes may be worse among dehydrated patients because their blood may be thicker than patients with adequate body fluid levels, according to study author Dr. Mona Bahouth, a cerebrovascular fellow in the department of neurology at Johns Hopkins Hospital in Baltimore. "I think we had a hunch ... that hydration would be a key feature for stroke patients," Bahouth said. "So it's not too surprising, but it's just the beginning. Now we need to figure out what to do with the [findings]." The research is ... Read more

Some Stroke Survivors May Face Heightened Cancer Risk, Study Shows

Posted 12 Feb 2015 by

THURSDAY, Feb. 12, 2015 – Older adults who survive a stroke may have a higher-than-average risk of developing cancer in the next few years, a new study suggests. Researchers followed nearly 3,700 ischemic stroke survivors who were started out cancer-free. Over two years follow-up, 2 percent were newly diagnosed with cancer. The researchers determined their risk of a cancer diagnosis was 40 percent higher than the norm for older U.S. adults. Experts said it's not clear why the risk was elevated. That's likely because the study wasn't designed to discover a cause. It was only designed to look for a link between these conditions. But the association may have something to do with risk factors that underlie both stroke and certain cancers, such as smoking or unhealthy eating habits. Another potential culprit is chronic, low-grade inflammation – which is believed to contribute to both heart ... Read more

Lower Blood Pressure Reduces First Stroke Risk: Study

Posted 11 Feb 2015 by

WEDNESDAY, Feb. 11, 2015 – Keeping the top number in a blood pressure reading below 140 helps reduce the risk of stroke in healthy people 60 and older, according to a new study. The findings challenge a report published last year in the Journal of the American Medical Association. The 2014 report said that doctors should aim for blood pressure readings of 150/90 mm Hg or lower for patients 60 and older who do not have diabetes or chronic kidney disease. That top number (the "systolic" reading) is 10 points higher than in previous recommendations and triggered controversy in the medical community. High blood pressure "is the most established and modifiable risk factor for stroke, one of the leading causes of death and disability," lead author of the new study, Chuanhui Dong, research associate professor at the University of Miami Miller School of Medicine, said in an American Stroke ...
