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

Less Heart Care, More Strokes for Women?

Posted 9 Jun 2016 by Drugs.com

THURSDAY, June 9, 2016 – Women in the United States with the common heart rhythm disorder atrial fibrillation are more likely than men with the condition to suffer a stroke, a new study shows. Atrial fibrillation is a quivering or irregular heartbeat. This study of 1 million patients with atrial fibrillation found that women were 23 percent more likely to be hospitalized for stroke than men. "There is a debate about whether it's the biology and something naturally in women that predisposes them to stroke or whether health care providers are failing to give adequate care," said researcher Dr. Ghanshyam Shantha. He is a cardiovascular disease fellow at the University of Iowa Hospitals and Clinics. "Our findings corroborate the previous evidence that women receive less treatment and support the conclusion that the gender discrepancy is due to inadequate stroke prevention care in women and ...

Women Less Likely to Get Blood Thinner for Irregular Heartbeat

Posted 8 Jun 2016 by Drugs.com

WEDNESDAY, June 8, 2016 – Among people with the common heart rhythm disorder known as atrial fibrillation, women are less likely than men to receive blood-thinning drugs, a new study reveals. Blood thinners are important for people with atrial fibrillation because they help prevent stroke. Atrial fibrillation causes an irregular heartbeat. In people with atrial fibrillation, blood doesn't move from one part of the heart to the other as it should. Instead, the blood can pool and may clot. If a clot travels to the brain, it can cause a stroke. Blood-thinning drugs can help keep clots from forming, according to the U.S. National Heart, Lung, and Blood Institute. For the study, researchers reviewed data from nearly 1,600 people with atrial fibrillation. Among these patients, 55 percent of women were taking blood thinners, compared with 61 percent of men. "The irony is that women have a ... Read more

Is Daily Blood Thinner Needed for Irregular Heartbeat?

Posted 7 May 2016 by Drugs.com

FRIDAY, May 6, 2016 – A smartphone app might offer an alternative for certain patients with an irregular heartbeat who must take risky blood-thinning medication every day to lower their risk for stroke. New research suggests some people with atrial fibrillation might do just as well by diligently monitoring their pulse, perhaps recording their heartbeat via a smartphone EKG, and only taking such drugs on an as-needed basis. Atrial fibrillation is a serious condition characterized by an abnormal or irregular heart rhythm. Uncontrolled, it can lead to blood clotting and stroke. Blood-thinning drugs, called anticoagulants, are the usual treatment. For years, the blood thinner warfarin (Coumadin) has been the top go-to drug for such patients. "The problem is that long-term use of anticoagulants is associated with an increased risk of bleeding," explained study co-author Dr. Francis ... Read more

Race May Influence Risk for Irregular Heart Beat

Posted 5 May 2016 by Drugs.com

THURSDAY, May 5, 2016 – There's a strong link between the heart rhythm disorder atrial fibrillation and race, a new study says. Whites with heart failure are much more likely to have atrial fibrillation (AF) than blacks or Hispanics with heart failure, the study authors said. Heart failure is a common risk factor for atrial fibrillation. Heart failure affects 5.8 million people in the United States and more than 23 million worldwide, the researchers said. The researchers reviewed information from more than 68,000 Americans with heart failure. They were between ages 45 and 95. The group included more than 28,000 Hispanics, more than 25,000 blacks and more than 14,000 whites. The risk of atrial fibrillation (AF) was about 23 percent lower in blacks than whites. The odds were nearly 27 percent lower in Hispanics than whites, the researchers found. The study was presented Wednesday at the ... Read more

Warfarin Can Be Safe, Effective for People With Irregular Heartbeat

Posted 20 Apr 2016 by Drugs.com

WEDNESDAY, April 20, 2016 – Millions of American heart patients take warfarin – for decades a cheap, but often tricky-to-manage mainstay blood thinner. Now, new research shows that when it is well-managed, warfarin treatment appears safe for people with atrial fibrillation, a common heart rhythm disorder. "Well-managed warfarin treatment is a valid alternative in patients with atrial fibrillation who require anticoagulant treatments, with relatively low complication rates and low all-cause [death rates]," concludes a team led by Dr. Fredrik Bjorck of Umea University in Sweden. The findings come in the context of newer, but much pricier, blood thinners – drugs such as Eliquis, Pradaxa and Xarelto. One expert who reviewed the new study said he would still opt for these medications over warfarin, because they are so much easier to manage. "In my opinion, the benefits of improved patient ...

Many With Irregular Heartbeat Missing Out on Stroke-Preventing Treatments

Posted 16 Mar 2016 by Drugs.com

WEDNESDAY, March 16, 2016 – Doctors know that a heart rhythm disorder called atrial fibrillation increases the odds for stroke. But less than half of "a-fib" patients at highest risk for stroke are prescribed recommended blood thinners by their cardiologists, new research finds. "The findings of our study are surprising given that these patients with atrial fibrillation were treated by a cardiovascular specialist, who should be aware of guideline recommendations" for anticoagulants, such as warfarin, said study lead author Dr. Jonathan Hsu. He is a cardiologist and assistant professor of medicine at the University of California, San Diego. Hsu's team tracked more than 400,000 atrial fibrillation patients in the United States for four years. The investigators found that most were prescribed blood-thinning drugs up to a point. But more than 50 percent of the very highest-risk patients ... Read more

Most Don't Need 'Bridging' When They Stop Warfarin Temporarily

Posted 26 Aug 2015 by Drugs.com

WEDNESDAY, Aug. 26, 2015 – Heart patients on the clot-preventing drug warfarin usually have to stop the medication before having surgery. Now, a new study shows they can safely do that without taking another anti-clotting drug – and they may even be better off. The study, reported in the Aug. 27 New England Journal of Medicine, helps answer long-standing questions about how to manage patients taking warfarin (Coumadin) for an irregular heart rhythm known as atrial fibrillation. Because warfarin is a powerful anticoagulant – which means it prevents blood clots – it can also raise the risk of internal bleeding. That's why people typically have to stop using warfarin in the days before and after an elective surgery. But it hadn't been clear whether those patients need what doctors call "bridging anticoagulation." That means taking another type of anti-clotting medication that is ... Read more

Antibiotic May Lower Effect of Some Blood Thinners

Posted 21 Jul 2015 by Drugs.com

TUESDAY, July 21, 2015 – The antibiotic dicloxacillin may lessen the effects of some blood-thinning medications, new research shows. "The surprise in the study was just how much of an impact dicloxacillin had," said study author Anton Pottegard, a pharmacist and research fellow at the University of Southern Denmark, in Odense. "Often, the effects in these kinds of studies are quite small. But this was very pronounced: Six out of 10 patients dropped so much in their level of blood-thinning that they were no longer sufficiently protected against clotting and stroke," Pottegard said. Coumadin (warfarin) and similar blood thinners lower the risk of blood clots, a potential cause of strokes and heart attacks, by thinning the blood so blockages don't form in vessels, according to the U.S. National Library of Medicine. Patients with irregular heart rhythms, such as atrial fibrillation, and ... Read more

White Men May Get Better Treatment for Abnormal Heartbeat

Posted 30 Jun 2015 by Drugs.com

TUESDAY, June 30, 2015 – Women, Hispanics and blacks are less likely than white men to receive optimal treatment for atrial fibrillation in the United States, researchers say. The study of more than a half-million Medicare patients found that women with this abnormal heart rhythm are less likely than men to get blood thinners to prevent stroke, which is a serious risk with atrial fibrillation. Women, blacks and Hispanics are also less likely to get catheter ablation, a surgical procedure that can restore the heart's normal rhythm. "Across the board, women are offered less aggressive care, particularly in cardiology," said lead researcher Dr. Prashant Bhave, a clinical assistant professor of internal medicine at University of Iowa Health Care. "There are still gaps in how patients are treated," he said. "The most important one is the difference in prescribing blood thinners. Ablation ... Read more

Drug May Be Antidote to Bleeding Tied to Blood Thinner Pradaxa

Posted 22 Jun 2015 by Drugs.com

MONDAY, June 22, 2015 – The new blood thinner Pradaxa (dabigatran) is being widely used, but it comes with one serious drawback: rare but dangerous cases of sudden, uncontrolled bleeding in patients. Now, a new study finds than an experimental, injected drug called idarucizumab could be used to quickly stop that bleeding. "Idarucizumab completely reversed the anticoagulant [bleeding] effect of dabigatran within minutes," researchers say in a study published online June 22 in the New England Journal of Medicine. In recent years, new-generation blood thinners such as Pradaxa have been approved as more manageable alternatives to older drugs such as warfarin. Unlike warfarin, these drugs "do not require blood tests for monitoring... while offering similar results in terms of effectiveness," explained Dr. Kevin Marzo, chief of cardiology at Winthrop-University Hospital in Mineola, N.Y. ...

Blood Thinner Warfarin May Pose Greater Bleeding Risk for Obese: Study

Posted 8 May 2015 by Drugs.com

FRIDAY, May 8, 2015 – Obese patients taking the blood thinner warfarin appear to have almost twice the risk of severe stomach bleeding compared to their normal-weight counterparts, a new study suggests. Why obese patients may be at greater risk for stomach bleeding isn't clear, according to the study. But Dr. Richard Hayes, a cardiologist at Lenox Hill HealthPlex in New York City, said it isn't surprising that obese patients taking warfarin may have a higher risk for stomach bleeding. "Obese patients have more medical problems, such as high blood pressure and diabetes," he said. "Therefore, they are more likely to be on other medications, many of which interfere with warfarin." Hayes was not involved in the new research, but reviewed the study's findings. Warfarin is taken to prevent heart attacks and stroke. It is often prescribed for patients with atrial fibrillation – an abnormal ... Read more

Device May Pose Dangers for Patients With Irregular Heartbeat: Study

Posted 4 May 2015 by Drugs.com

MONDAY, May 4, 2015 – Heart surgeons are making regular and potentially dangerous "off-label" use of a suturing device in patients with abnormal heart rhythms, researchers report. Though the Lariat device can be used to tie off a part of the heart that raises stroke risk, it has not been approved by the U.S. Food and Drug Administration for this specific purpose. And a small number of atrial fibrillation patients have needed lifesaving surgery or died following this off-label procedure, the study authors discovered. "We found a handful of deaths, and a greater handful in which there was the need for an urgent open-heart surgery to correct a problem" involving bleeding or damage done to the heart during the procedure, said lead researcher Dr. Jay Giri. He is an assistant professor of cardiovascular medicine with the Perelman School of Medicine at the University of Pennsylvania, in ... Read more
