Stroke Patients May Face Increased Risk of Suicide

Posted 17 days ago by

WEDNESDAY, April 8, 2015 – Stroke patients are at significantly increased risk of suicide, especially during the first two years following the brain attack, a new Swedish study shows. Researchers analyzed data from more than 220,000 people in Sweden who suffered a stroke between 2001 and 2012. They found that stroke patients were up to twice as likely to commit suicide as people in the general population, and the risk of attempted suicide was highest in the first two years after a stroke. Among stroke patients younger than 55, the risk of suicide was five times higher than in the general population. And stroke patients with lower income or education levels were 37 percent more likely to try to take their lives than those with a university education. The Umea University researchers also found that stroke patients who lived alone were 72 percent more likely to attempt suicide than those ... Read more

Pouch in Heart May Trigger Unexplained Strokes: Study

Posted 18 days ago by

TUESDAY, April 7, 2015 – A pouch-like structure in the heart may be the source of some strokes that have no other known cause, a new study suggests. This pouch in the heart's left atrial chamber – called a left atrial septal pouch – was first discovered in 2010 by cardiologists at the University of California, Irvine. "The cul-de-sac nature of this heart pouch may promote stagnation of the blood, forming clots that can travel into the brain and cause a stroke," Dr. Mark Fisher, a professor of neurology and pathology and laboratory medicine, said in a UC Irvine news release. The researchers looked at 75 stroke patients to find out if the pouch could be a source of stroke-causing blood clots. Of the 23 patients who had a stroke of undetermined origin, 30 percent had a left atrial septal pouch, compared with only 10 percent of the 52 patients whose cause of stroke could be pinpointed. ...

Packaged Grocery Foods Often High in Salt, Study Finds

Posted 2 Apr 2015 by

THURSDAY, April 2, 2015 – More than half of packaged grocery store foods included in a new study contained too much added salt, U.S. health officials reported Thursday. That's important because eating too much salt (sodium) is a risk factor for developing high blood pressure, according to the study authors. And high blood pressure can contribute to heart disease and strokes. "We looked at packaged food sales in grocery stores," said study researcher Linda Schieb, an epidemiologist in the division of heart disease and stroke prevention at the U.S. Centers for Disease Control and Prevention. "What we found was more than 50 percent of those products exceeded the FDA healthy food label guidelines for sodium." Under the U.S. Food and Drug Administration healthy food label guideline, only 480 milligrams (mg) of sodium per serving are allowed for individual foods – such as cheese, cold cuts ... Read more

More People Dying of Heart Disease, Stroke Worldwide: Study

Posted 2 Apr 2015 by

THURSDAY, April 2, 2015 – Despite medical advances, a new study shows that more people are dying of heart disease and stroke worldwide than did a quarter century ago because the global population is growing, and growing older. The good news is that the death rate – the number of deaths in relation to the size of the population – fell in most regions of the world. The declining death rate reflects better diets, less tobacco smoking and improvements in medicine, said Dr. Simon Capewell, a professor of clinical epidemiology at the University of Liverpool in England. However, the numbers are still too high, said Capewell, who was not involved in the study. "A lot of these deaths are premature, meaning they kill people below the age of 75," Capewell said. "Ninety percent of these premature deaths are preventable and avoidable through healthy diets and zero smoking." In the study, ... Read more

New Stroke Prevention Efforts May Be Paying Off

Posted 31 Mar 2015 by

TUESDAY, March 31, 2015 – Fewer people are being treated in U.S. emergency rooms for strokes caused by blood clots in the brain, which experts read as a sign that current stroke prevention methods are working. The rate of emergency department visits for either a stroke or a mini-stroke (transient ischemic attack) – a temporary blockage of blood flow to the brain – decreased dramatically between 2001 and 2011, according to a new U.S. Centers for Disease Control and Prevention report. Such ER visits declined 35 percent for adults 18 and older, and 51 percent for those 55 to 74, said the report from the CDC's National Center for Health Statistics (NCHS). The statistics mirror a "dramatic reduction in stroke fatality in the country, which we believe is likely due to better control of risk factors," said Dr. Larry Goldstein, chief of the division of stroke and vascular neurology and ...

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
