One-Third With Atrial Fibrillation Don't Take Blood Thinners

Posted 12 days ago by Drugs.com

FRIDAY, Jan. 6, 2017 – Many people with the heart condition known as atrial fibrillation stop taking the blood-thinning medication that's prescribed to help prevent a stroke, a new study reveals. Atrial fibrillation is an irregular heartbeat that causes the heart to quiver. This raises the risk of blood clots and stroke, according to the American Heart Association. People who've had a medical procedure such as cardioversion (electrical shocks to the heart through electrodes placed on the chest) or ablation (using heat, cold or radio energy to scar heart tissue via catheter or surgery) to help manage their condition were even more likely to ditch their prescribed drugs. "We don't know if changing the heart to a normal rhythm, by either cardioversion or ablation, always removes the risk of stroke," said study author Dr. Geoffrey Barnes, a cardiologist at the University of Michigan ...

Head Off 'Holiday Heart Syndrome'

Posted 23 Dec 2016 by Drugs.com

FRIDAY, Dec. 23, 2016 – Overindulging over the holidays can take a toll on the heart, according to experts at UT Southwestern Medical Center in Dallas. Heavy drinking and eating too much, especially salty foods, can trigger atrial fibrillation. A-fib is an irregular heartbeat that causes the upper chambers of the heart to contract rapidly, increasing the risk for stroke. People with the condition may feel short of breath, have heart palpitations and feel like their heart is beating much faster than usual. During December when holiday revelry peaks, emergency rooms see a surge of patients with what's unofficially dubbed "holiday heart syndrome" from too much food and drink, according to UT Southwestern cardiologist Dr. Sharon Reimold. "It's common for people to go to multiple parties during this time of year. You go to one party and have a drink or two, go to the next party and have a ... Read more

Regular Drinkers, Irregular Heartbeat?

Posted 5 Dec 2016 by Drugs.com

MONDAY, Dec. 5, 2016 – Regularly drinking even small amounts of alcohol may boost the risk of an irregular heartbeat known as atrial fibrillation, a new research review finds. "The results are significant, since chances are, there are people who are consuming one to two glasses of alcohol per day that may not realize they are putting themselves at risk for irregular heartbeat," said study lead author Dr. Peter Kistler. He is head of clinical electrophysiology research at the Baker IDI Heart and Diabetes Institute in Melbourne, Australia. Other research has linked light-to-moderate alcohol use (up to two standard drinks a day for men and one for women) to better heart health for some people. The new research suggests that this may not apply to atrial fibrillation, which boosts the risk of heart-related problems and stroke. The authors of the new study reviewed prior research that ...

Drug Combo for Irregular Heartbeat Might Raise Bleeding Risk

Posted 21 Nov 2016 by Drugs.com

MONDAY, Nov. 21, 2016 – Because the irregular heartbeat known as atrial fibrillation can trigger stroke-inducing clots, many patients are prescribed a blood thinner. But a new Canadian study suggests that combining one blood thinner, Pradaxa, with certain statin medications could raise the odds for bleeding in these patients. "An increase in the risk of bleeding requiring hospital admission or emergency department visits was seen with lovastatin [Mevacor] and simvastatin [Zocor] compared with the other statins," said study author Tony Antoniou, a pharmacist at St. Michael's Hospital in Toronto. His team tracked outcomes for nearly 46,000 patients ages 65 and older. All had atrial fibrillation and took Pradaxa (dabigatran) to reduce their risk of stroke. Those who also took either lovastatin or simvastatin had a 40 percent higher risk of bleeding than those who took other statins, the ... Read more

Lifestyle, Stress May Play Role in Heart Rhythm Disorder

Posted 20 Nov 2016 by Drugs.com

SATURDAY, Nov. 19, 2016 – Stress and poor heart-health habits significantly increase the risk of a common heart rhythm disorder called atrial fibrillation, two preliminary studies suggest. The irregular or quivering heartbeat associated with atrial fibrillation can lead to blood clots, stroke, heart failure and other heart-related complications, the American Heart Association says. One new study included more than 6,500 adults without heart disease. They were rated on seven factors related to heart health: smoking, body mass index, physical activity, diet, total cholesterol, blood pressure and blood sugar. The heart association calls these Life's Simple 7. Compared to those with the worst scores, adults who scored highest were 41 percent less likely to develop atrial fibrillation. Those with average scores were 8 percent less likely to develop the abnormal heartbeat. Although the ... Read more

Many With Common Irregular Heartbeat Unaware of Stroke Risk

Posted 16 Nov 2016 by Drugs.com

WEDNESDAY, Nov. 16, 2016 – Nearly one-third of Americans newly diagnosed with the common heart rhythm disorder atrial fibrillation (AF) don't realize the condition puts them at increased risk for stroke, a new study finds. The irregular heartbeat in AF patients can cause blood to pool, which can cause blood clots that can lead to stroke, researchers explained. The study revealed misconceptions some patients had about atrial fibrillation. "This helps us see gaps in knowledge and understanding," said lead author Emily O'Brien, from the Clinical Research Institute at Duke University in Durham, N.C. O'Brien and her team surveyed 1,000 people diagnosed with atrial fibrillation in the past six months. Their median age was 69. About 63 percent strongly agreed that stroke is a major risk factor of atrial fibrillation. However, around 32 percent believed that heart attack is a major risk factor ... Read more

Many Atrial Fibrillation Patients Missing Out on Blood Thinners

Posted 16 Nov 2016 by Drugs.com

WEDNESDAY, Nov. 16, 2016 – Half of patients hospitalized with the heart rhythm disorder atrial fibrillation aren't given blood-thinning drugs that reduce the risk of clots and stroke, a new study finds. Atrial fibrillation, a type of irregular heartbeat, puts people at higher risk for blood clots and stroke, researchers from Duke University said. They analyzed nearly 1.6 million admissions for atrial fibrillation at 812 hospitals across the United States over five years and found that only 46 percent of patients received blood thinners at discharge. "This low rate of [blood thinner] use in hospitalized patients highlights an important opportunity to improve care in atrial fibrillation patients," said study co-author Dr. Sean Pokorney, an electrophysiology fellow at Duke School of Medicine in Durham, N.C. The patients in the study were 40 and older, stayed in the hospital for at least ... Read more

Trouble Sleeping Tied to Higher Risk for Irregular Heartbeat

Posted 14 Nov 2016 by Drugs.com

MONDAY, Nov. 14, 2016 – There may be yet another reason to try and get a good night's sleep: New research ties poor sleep to a higher odds for a dangerous irregular heartbeat. The condition in question is called atrial fibrillation, a common heart arrhythmia that is strongly tied to an increased risk for clotting and strokes. Now, two studies suggest that trouble getting your Zzzs may raise the risk for atrial fibrillation. One cardiologist who reviewed the studies said the theory may have merit. While neither study could prove cause-and-effect, changes in a person's physiology by a "disturbed sleep cycle may be the mechanism for development and recurrence of atrial fibrillation," said Dr. Jianqing Li. She's a cardiologist at Winthrop-University Hospital in Mineola, N.Y. In one study, a team led by Dr. Gregory Marcus of the University of California, San Francisco, tracked data from ... Read more

Irregular Heart Rhythm Patients May Not Always Need Blood Thinners: Study

Posted 18 Oct 2016 by Drugs.com

TUESDAY, Oct. 18, 2016 – People with an abnormal heart rhythm called atrial fibrillation typically take powerful blood thinners to prevent strokes. But, some patients who have implanted pacemakers or defibrillators may not always need the drugs, a new study suggests. Those who suffered only short bouts of atrial fibrillation – estimated at 20 seconds or less – were at no more risk for stroke or other heart complications than people without atrial fibrillation, the researchers found. "Some patients have atrial fibrillation 100 percent of the time, while others might have only a few seconds of atrial fibrillation once a year," explained study author Dr. Steven Swiryn. He's a clinical professor of cardiology at the Feinberg School of Medicine at Northwestern University in Chicago. "Where atrial fibrillation only happens rarely and lasts a short time, it can be difficult to detect," ... Read more

Sleep Apnea May Boost Risk for Post-Op Problems

Posted 17 Oct 2016 by Drugs.com

MONDAY, Oct. 17, 2016 – Sleep apnea may boost the odds of developing two serious health complications following surgery. So, finding out if you have the sleep disorder beforehand – and seeking treatment – could boost your odds for good recovery from surgery, researchers say. The two post-op complications are blood clots in the veins and an irregular heartbeat called atrial fibrillation, according to two new studies. These problems occurred more often among surgical patients who had not yet been diagnosed – and therefore weren't treated – with sleep apnea. Obstructive sleep apnea is characterized by repeated breathing disruptions during sleep. Symptoms include excessive daytime sleepiness, restless sleep and loud snoring – often with periods of silence followed by gasps. More than half of surgery patients who have sleep apnea don't know it, the authors of one new study said. ... Read more

Some Increased Bleeding Risk Seen With Blood Thinner Xarelto Vs. Pradaxa

Posted 3 Oct 2016 by Drugs.com

MONDAY, Oct. 3, 2016 – The blood thinner Xarelto may pose a slightly greater risk of serious bleeding than Pradaxa in patients with the abnormal heartbeat known as atrial fibrillation, new research suggests. Most patients with the condition take a blood thinner to reduce the risk of stroke. Although these drugs help prevent stroke, they can also cause uncontrollable bleeding, which can be fatal, the researchers said. Two newer drugs – Xarelto (rivaroxaban) and Pradaxa (dabigatran) – are replacing the older drug warfarin, a medication that is notoriously difficult to monitor. Which of these newer drugs is safer, however, hasn't been proven, said the U.S. Food and Drug Administration researchers behind the new study. "There are now several new oral anticoagulants and we don't have a lot of studies that compare one to the other," said Dr. Rita Redberg. A professor of cardiology at the ... Read more

Heart Rhythm Disorder May Be Tied to Wider Range of Ills

Posted 7 Sep 2016 by Drugs.com

WEDNESDAY, Sept. 7, 2016 – Atrial fibrillation, a common type of heart rhythm disorder, is associated with a wider range of conditions than previously believed, researchers report. The findings add "to the growing literature on the association between atrial fibrillation and cardiovascular outcomes beyond stroke," researchers at the University of Oxford in England and the Massachusetts Institute of Technology wrote. The team reviewed 104 studies involving more than 9 million people, including nearly 590,000 people with atrial fibrillation. They concluded that the heart rhythm disorder was also associated with heart disease, heart failure, kidney disease, sudden cardiac death and death from all causes. The study did not prove atrial fibrillation caused these additional health risks, just that there was an association. Risk for heart failure was the most significant of these ... Read more

Irregular Heartbeat More Deadly in Blacks: Study

Posted 22 Jun 2016 by Drugs.com

WEDNESDAY, June 22, 2016 – Black Americans with a common heart rhythm disorder are at higher risk than whites for serious heart complications and death, a new study finds. The disorder, called atrial fibrillation, affects about 1 percent of American adults and more than 5 percent of those 65 and older. Atrial fibrillation can raise a person's risk for stroke. The new findings may "put the focus on improving prevention efforts for adverse outcomes in blacks with atrial fibrillation," said study lead author and cardiologist Dr. Jared Magnani. The research might also "drive further studies into the reasons behind why this is happening," said Magnani, of the University of Pittsburgh Medical Center's Heart and Vascular Institute. The study included more than 15,000 blacks and whites, average age 54, who were followed for an average of 21 years. During that time, nearly 2,350 cases of atrial ... Read more

Aspirin Often Wrongly Prescribed for Atrial Fibrillation

Posted 20 Jun 2016 by Drugs.com

MONDAY, June 20, 2016 – More than one-third of U.S. patients with the abnormal heartbeat atrial fibrillation who need a blood thinner to prevent strokes aren't getting one, researchers say. About 40 percent of "a-fib" patients deemed at moderate to severe risk of stroke because of age or other conditions are prescribed aspirin alone rather than recommended blood thinners such as Xarelto (rivaroxaban) or warfarin, according to a new study. "Despite clear guideline recommendations that patients at risk for stroke that have atrial fibrillation should be given blood thinners, many of these patients are not prescribed these potentially lifesaving medications," said lead researcher Dr. Jonathan Hsu. He is an assistant professor of medicine, cardiology and cardiac electrophysiology at the University of California, San Diego. Another heart specialist agreed. "Aspirin is not an anticoagulant ...

Irregular Heartbeat May Be Deadly in Car Crash

Posted 10 Jun 2016 by Drugs.com

FRIDAY, June 10, 2016 – Having the common heart rhythm disorder atrial fibrillation might be risky if you get into a car accident, a new study suggests. Atrial fibrillation is a quivering or irregular heartbeat. Researchers report the condition is linked to higher chances of dying if you're in a crash, although their study didn't prove a cause-and-effect relationship. "Atrial fibrillation is the most common heart rhythm disorder, and incidence is rising. Many of these patients are on anticoagulants to lower their stroke risk, but these drugs increase the chance of bleeding," said study author Dr. Abhishek Deshmukh, a cardiologist at the Mayo Clinic in Rochester, Minn. However, "we should not jump the gun and advise patients with atrial fibrillation to stop driving. This was a retrospective observational study and needs to be confirmed by further research," he said in an European ... Read more
