Working Too Much Might Tip Heart Into Irregular Rhythm

Posted 8 days ago by Drugs.com

FRIDAY, July 14, 2017 – Working long hours might do more than exhaust you – it could also raise your risk of a common and potentially dangerous heart rhythm disorder, a new British study finds. "These findings show that long working hours are associated with an increased risk of atrial fibrillation, the most common cardiac arrhythmia," said study leader Mika Kivimaki, a professor of epidemiology at University College London. Because atrial fibrillation has long been a known risk factor for stroke, "this could be one of the mechanisms that explain the previously observed increased risk of stroke among those working long hours," Kivimaki said in a news release from the European Heart Journal. His team published their findings in the journal on July 14. One cardiologist in the United States said that because the study couldn't prove cause-and-effect, its results "need to be interpreted ...

Early Care by Cardiologist May Lower Stroke Risk for A-Fib Patients

Posted 26 Jun 2017 by Drugs.com

MONDAY, June 26, 2017 – Patients with a common heart rhythm disorder who receive a cardiologist's care soon after diagnosis are less likely to suffer a stroke, a new study finds. Atrial fibrillation, or A-fib, is an irregular, often rapid heart rate that increases the risk of stroke and other complications. It affects between 3 million and 5 million Americans. Researchers from Stanford University School of Medicine analyzed data on more than 184,000 people diagnosed with atrial fibrillation between 2004 and 2012. Within 90 days of diagnosis, 40 percent were cared for by a cardiologist and 60 percent by a primary care doctor only. Patients seen by cardiologists had a 9 percent lower risk of stroke and an 11 percent lower risk of early death, the study found. The lower stroke risk probably resulted from a higher rate of prescriptions for blood-thinning drugs that prevent blood clots, ... Read more

Are Many A-Fib Patients Getting Wrong Doses?

Posted 5 Jun 2017 by Drugs.com

MONDAY, June 5, 2017 – Nearly one in six Americans who takes newer blood thinners for the heart rhythm problem atrial fibrillation may not receive the proper dose, a new study suggests. A-fib is a common condition, marked by an irregular and often rapid heart beat. It's associated with a fivefold increased risk of stroke, but blood thinners reduce that risk. Many a-fib patients also have kidney disease and need a lower medication dose than others, the study authors said. "Dosing errors of these blood-thinning medications in patients with atrial fibrillation are common and have concerning adverse outcomes," said lead author Xiaoxi Yao, a researcher at the Mayo Clinic in Rochester, Minn. Moreover, "the number of patients using these drugs has quickly increased since the introduction of this new class of drugs in 2010," Yao said in a Mayo news release. The researchers looked at nearly ... Read more

Could Chocolate Guard Against an Irregular Heartbeat?

Posted 24 May 2017 by Drugs.com

TUESDAY, May 23, 2017 – There's delicious news for chocolate lovers: New research suggests the sweet might help keep a common and dangerous form of irregular heartbeat at bay. The study of more than 55,000 people in Denmark found that those who favored chocolate tended to have a lower risk of atrial fibrillation, an irregular heartbeat that raises stroke risk. The study tracked people's health for more than 13 years, over which time more than 3,300 cases of atrial fibrillation emerged. The study wasn't designed to prove cause and effect. However, compared with people who ate a 1-ounce serving of chocolate less than once a month, the risk of atrial fibrillation was 10 percent lower among those who ate one to three servings a month, 17 percent lower among those who ate one serving a week, and 20 percent lower among those who ate two to six servings of chocolate a week. But the benefit ... Read more

Sleep Apnea May Boost Odds of Irregular Heartbeat

Posted 23 May 2017 by Drugs.com

TUESDAY, May 23, 2017 – People with sleep apnea may be more likely to develop the abnormal heart rhythm atrial fibrillation, especially if the oxygen level in their blood drops below normal, Canadian researchers report. Sleep apnea, which obstructs breathing, causes people to wake many times during the night to start breathing again. It's possible, researchers said, that disrupted sleep along with a drop in the level of oxygen in the blood might lead to atrial fibrillation. Atrial fibrillation causes a rapid and irregular heartbeat. This can lead to stroke and heart problems. "Patients who are at risk for obstructive sleep apnea should undergo testing, particularly if they have other cardiac risk factors," said study senior researcher Dr. Richard Leung, an assistant professor of medicine at the University of Toronto. "Therapy should be strongly considered for patients who have ... Read more

Heart Health Might Be a Matter of Geography

Posted 16 May 2017 by Drugs.com

TUESDAY, May 16, 2017 – The county you call home may have a lot to do with your chances of dying from heart disease or stroke, a new U.S. study reveals. Although deaths from cardiovascular disease have been dropping overall for the past 35 years in the United States, there are still pockets across the country where these death rates are unusually high, the researchers said. Poverty and lack of access to quality care may doom many Americans to early deaths, the study authors suggested. "In some counties, the risk of dying from cardiovascular disease is extremely low, while in other counties the risk continues to be very high," said lead researcher Dr. Gregory Roth. He is an assistant professor of cardiology at the University of Washington. In Pitkin County in Colorado, for example, about 35 people out of 100,000 died from heart disease in 2014 – the lowest death rate in the United ... Read more

Better Treatment Might Prevent Hundreds of Thousands of Strokes

Posted 15 May 2017 by Drugs.com

MONDAY, May 15, 2017 – Hundreds of thousands of strokes might be prevented in the United States each year if more people with a heart rhythm disorder called atrial fibrillation took blood-thinning medications, a new study estimates. Atrial fibrillation causes the heart to quiver instead of beating normally. This causes blood to pool and possibly clot, according to the American Heart Association. If one of those clots breaks free, it can go to the brain and cause a stroke. "Though not a life-threatening rhythm abnormality per se, atrial fibrillation can be associated with devastating life-altering consequences, namely disabling stroke," said one expert, Dr. Nicholas Skipitaris. He directs cardiac electrophysiology at Lenox Hill Hospital in New York City. Unfortunately, too few people are getting the treatment for "a-fib" that they need, the new study found. Taking blood thinners might ... Read more

Blood Thinners May Prevent Dementia in Atrial Fibrillation Patients

Posted 14 May 2017 by Drugs.com

FRIDAY, May 12, 2017 – Blood thinners are often prescribed to prevent strokes in people with the abnormal heart rhythm known as atrial fibrillation. But a new study suggests these drugs may also help keep dementia at bay. The researchers said that the key is to start blood thinners, such as warfarin, soon after atrial fibrillation is diagnosed. That's true even for people at low risk of a stroke who wouldn't normally be given blood thinners. "We found that people who are on warfarin – the most common blood thinner used to prevent stroke in patients with atrial fibrillation – experienced very low rates of dementia, including Alzheimer's disease," said lead researcher Dr. T. Jared Bunch. He's director of heart rhythm research at Intermountain Medical Center Heart Institute in Murray, Utah. Atrial fibrillation is a common heart abnormality that affects nearly 3 million American adults. ... Read more

Taller, Bigger Women May Face Irregular Heartbeat Risk

Posted 10 Apr 2017 by Drugs.com

MONDAY, April 10, 2017 – Big or tall women are nearly three times as likely to develop the dangerous irregular heart rhythm known as atrial fibrillation as smaller women, a preliminary study says. The larger a woman's body size as a young adult, the more likely she is to develop the heart disorder later in life, according to the researchers. "There was a stepwise elevation in risk with increasing body size," said study author Dr. Annika Rosengren. "The group with the highest body surface area had nearly three times the risk as those with the lowest body surface area," added Rosengren, a professor of internal medicine at the University of Gothenburg in Sweden. Atrial fibrillation is an irregular heartbeat that develops in the atria – the two upper chambers of the heart. The quivering heartbeat increases risk of stroke, heart failure and other heart rhythm problems, according to the ... Read more

Heart Devices 101: Guide to the Tools That Keep You Ticking

Posted 3 Apr 2017 by Drugs.com

SUNDAY, April 2, 2017 – Pacemakers, defibrillators and other medical devices have saved the lives of millions of people worldwide. Someone you know probably has received one of these heart-health enhancers, although not all have become household words. The U.S. Food and Drug Administration evaluates and regulates these and other medical devices in the United States. Below, the agency provides a brief glossary of terms that might come in handy when a doctor recommends a cardiac tool: Heart pacemakers: These small, battery-powered devices are implanted in the body. They deliver an electric shock to restore normal heart rhythm when the heart beats too slowly. Implantable cardioverter defibrillators: These deliver a shock to restore normal heart rhythm when the heart beats too fast. Automated external defibrillators: These portable, automatic devices are found in many public locations. ... Read more

Exercise a Great Prescription to Help Older Hearts

Posted 24 Mar 2017 by Drugs.com

THURSDAY, March 23, 2017 – Regular exercise is potent medicine for older adults with heart disease, a new American Heart Association scientific statement says. Physical activity should be a key part of care for older adults with heart disease who want to reduce their symptoms and build their stamina, said geriatric cardiologist Dr. Daniel Forman. He's chair of the panel that wrote the new statement. "Many health-care providers are focused only on the medical management of diseases – such as heart failure, heart attacks, valvular heart disease and strokes – without directly focusing on helping patients maximize their physical function," Forman said in a heart association news release. Yet, after a heart attack or other cardiac event, patients need to gain strength. Their independence may require the ability "to lift a grocery bag and to carry it to their car," said Forman, a professor ... Read more

Heart Drug Digoxin May Raise Death Risk for Some Patients: Study

Posted 22 Mar 2017 by Drugs.com

WEDNESDAY, March 22, 2017 – The heart drug digoxin might raise the risk of death in people with a common heart rhythm disorder, and those patients should not take the drug, a new study suggests. Researchers analyzed data from nearly 18,000 atrial fibrillation patients in an international stroke prevention trial, including about 32 percent who were on digoxin at the start of the trial and nearly 7 percent who started taking the drug at some point during the trial. There was no significant association between digoxin use and death risk among patients who were already taking digoxin and therefore more likely to tolerate it, said study author Dr. Renato Lopes, a member of the Clinical Research Institute at Duke University in Durham, N.C. However, even among those patients, the risk of death was related to digoxin concentration in the blood. For every 0.5 nanograms per milliliter (ng/mL) ... Read more

Pradaxa Beats Warfarin After Heart Rhythm Procedure: Study

Posted 20 Mar 2017 by Drugs.com

MONDAY, March 20, 2017 – Patients undergoing a surgical procedure to treat an irregular heartbeat are less likely to suffer problematic bleeding when given the blood thinner Pradaxa rather than warfarin, a new study finds. The two blood thinners were evaluated in a study of more than 600 patients. All had a minimally invasive procedure called catheter ablation to correct the heart rhythm disorder known as atrial fibrillation. The risk of having a major bleeding event among patients taking warfarin (Coumadin) was about 7 percent, whereas the risk among those taking Pradaxa (dabigatran) was just under 2 percent, said lead researcher Dr. Hugh Calkins. "It's an absolute risk difference of 5 [percentage points], or a 77 percent lower risk," said Calkins, a professor of medicine at Johns Hopkins University School of Medicine in Baltimore. "I think this will change practice," he said. ... Read more

Are Blood Thinners Overused in Patients With Irregular Heartbeat?

Posted 17 Mar 2017 by Drugs.com

FRIDAY, March 17, 2017 – Many people living with the heart rhythm disorder known as atrial fibrillation may be taking unneeded blood thinners, a new study suggests. These blood thinners, which include aspirin, Plavix and warfarin, are believed to reduce the risk of stroke that can come with atrial fibrillation. But for many atrial fibrillation patients with a low stroke risk, the medications might actually increase both bleeding and stroke risk, researchers reported. The way most doctors decide whether a patient needs a blood thinner is by using a simple score called CHADS2, which assigns points to patients based on age and other medical risks. A score of 2 is usually needed to recommend a blood thinner, the researchers explained. But, "people are realizing that the CHADS2 scores are putting too many people above the threshold – it's pretty easy to get a 2," explained study author ... Read more

Many With Irregular Heartbeat Not on Meds They Need: Study

Posted 14 Mar 2017 by Drugs.com

TUESDAY, March 14, 2017 – Many people with an irregular heartbeat who suffer a stroke may not have been on medications that might have prevented their stroke, a new study suggests. Duke University researchers found that 84 percent of stroke patients with the heart condition known as atrial fibrillation (AF) had not been getting adequate clot-preventing therapy. Dr. David Wilber, a cardiologist at Loyola University Medical Center in Illinois, called the findings "sobering." "This emphasizes the fact that probably the most important cause of stroke in AF patients is under-anticoagulation or no anticoagulation," said Wilber, who is also editor-in-chief of the journal JACC: Clinical Electrophysiology. Study lead researcher Dr. Ying Xian agreed. "We estimate that the vast majority of these strokes could have been prevented if patients had the appropriate anticoagulation," said Xian, an ...
