People with a history of certain cancers have more than double the risk for the heart rhythm disorder atrial fibrillation, a new study says.

A-fib is a common disorder that can lead to palpitations, dizziness and fatigue. Untreated, it can cause blood clots, stroke and heart failure, and people with a-fib have five times the risk of stroke than other people.

"When we looked ...

People with the heart condition atrial fibrillation often use blood thinners to help prevent a stroke. Now a new study suggests one of those medications might stand out as safer and more effective.

Researchers found that a-fib patients on the drug Eliquis (apixaban) had a slightly lower risk of blood clots and stroke than those on Xarelto (rivaroxaban) -- a clot-preventing drug in the...

Too few Americans have quick access to a medical center that can perform a procedure to remove stroke-causing blood clots, new research shows.

For the study, researchers examined nationwide availability of endovascular thrombectomy -- removal of a blood clot with a mechanical device that's threaded through an artery.

It improves patients' outcomes if it's performed within 24...

Fewer U.S. veterans are having leg amputations or dying due to serious blockages in leg arteries, a new study finds.

These blockages are called critical limb ischemia (CLI). They can cause severe leg pain, wounds that don't heal and poor quality of life, according to the study published recently in the journal Circulation: Cardiovascular Interventions.

"All patients w...

Ambulances outfitted as "mobile stroke treatment units" provide faster treatment and reduce patients' risk of severe disability and death, German researchers report.

The new study examined the use of three mobile stroke units in Berlin. Each unit is staffed with emergency medicine neurologists and has a CT scanner and lab on board that enables treatment at the scene.

Treatme...

A noninvasive magnetic brain stimulation device worn less than an hour a day can increase activity near stroke-injured areas of the brain, a small, preliminary study suggests.

Those improvements in brain activity might then lead to increased motor function in people who have had a stroke, the researchers said.

"We were excited to see a strong hint of improved motor functio...

Gastrointestinal bleeding in patients taking blood thinners for an irregular heartbeat should prompt doctors to check for colon cancer, a new study advises.

Researchers looked at more than 125,000 patients in Denmark with the heart rhythm disorder atrial fibrillation (a-fib). They reported that those with gastrointestinal bleeding were 11 to 24 times more likely than others to be diag...

People with blood types A and B may have higher risks for developing dangerous blood clots compared to people who have type O blood. That's according to new research that also showed a slightly higher risk for certain types of heart disease among the A and B groups.

Past research has shown a likely link between heart disease and the ABO gene that exists in people with A, B or AB bloo...

Patients taking the blood thinner warfarin have been told that it should be taken at night, but a new study found the time of day doesn't matter.

"Whether warfarin is taken in the morning, or the evening, its therapeutic effect is the same," said lead researcher Dr. Scott Garrison, an associate professor of family medicine at the University of Alberta in Edmonton, Canada.

...

People with what's known as the "metabolic syndrome" are vulnerable to recurring blood clots, new research shows.

Metabolic syndrome is a collection of conditions, including obesity, high blood sugar, high cholesterol and high blood pressure. These factors put people at risk for diabetes, heart disease and a type of blood clot known as deep vein thrombosis (DVT), researchers say.

...

"Space medicine" took another small step forward after an astronaut who developed a blood clot in a neck vein was diagnosed and treated while onboard the International Space Station (ISS), physicians at NASA and elsewhere report.

The research team didn't reveal the astronaut's name, age or gender, but said the ISS crew member developed an asymptomatic thrombosis -- blood clot -- in th...

Testosterone therapy appears to double a man's risk of suffering a potentially life-threatening blood clot, a new study warns.

Men had twice the risk for a deep vein blood clot if they'd been receiving testosterone during the previous six months, researchers reported in the Nov. 11 online edition of JAMA Internal Medicine.

The increased risk occurred whether or not a ...

Men who are on the blood-thinning drug warfarin have more difficulty taking the medication if they live alone, but the same is not true for women, a new study finds.

Warfarin (brand-name Coumadin) is a common anti-clotting treatment to prevent stroke in people with atrial fibrillation, the most common type of heart rhythm disorder.

Continuous bloo...

Black and Hispanic people having a stroke are less likely than their white counterparts to get treatments proven to reduce death and improve quality of life, new research shows.

For strokes caused by a clot, the gold standard treatment is a clot-busting drug called alteplase, according to guidelines from the American Heart Association and American Stroke Association. Some people migh...

Former pro football players typically have healthier hearts than the average Joe -- except when it comes to a type of heart rhythm disturbance, a new study suggests.

Researchers found that former NFL players had a nearly six times higher rate of atrial fibrillation (a-fib), versus other men their age. The condition was present in 5% of 460 former players, versus 0.5% of nonath...

A urinary tract infection might be more than just a painful nuisance for some, with new research suggesting it could raise the risk of stroke in vulnerable people.

The study of over 190,000 stroke patients found that the risk of suffering a stroke was heightened in the weeks and months following any infection that required a trip to the hospital. But urinary tract infections (UTIs) sh...

Cautions about TV viewing are as old as television itself, but how bad is it really?

A number of studies cite health risks due to the link between a sedentary lifestyle and the number of hours spent watching the tube.

Young adults who watch three or more hours of TV a day and get little exercise have a greater chance of cognitive issues in midlife, according to a 25-year st...

Spinach-loving seniors, rejoice. A new study suggests that -- despite doctor warnings to the contrary -- you can eat leafy greens rich in vitamin K if you are taking the blood thinner warfarin.

In fact, "I think all warfarin-treated patients would benefit from increasing their daily vitamin K intake," said lead author Guylaine Ferland. She's a professor of nutrition at University of ...

Older age raises the odds of many ills, but for adults with gout, it's the younger ones who have the highest risk for developing a serious blood clot, new research indicates.

Gout patients of any age have a 25% greater risk of developing a blood clot deep in the veins in the first 10 years after diagnosis, the British study found.

But "the risk was 79% higher in gou...

Could electrical stimulation of nerves that sit behind your nose help limit the harm done to your brain by a stroke?

New research suggests it's possible. In early experiments, blood flow to the brain was increased by widening undamaged arteries and bypassing the clot. This delivered oxygen-rich blood to threatened areas of the brain.

How could that reduce disability after a ...

LDL cholesterol – the so-called "bad" cholesterol – is known to narrow arteries, which can lead to heart attacks and strokes. It's also now suspected of contributing to venous thromboembolism, new research suggests.

The preliminary study, presented Tuesday at the American Heart Association's Vascular Discovery Scientific Sessions, looked at genes and proteins that might i...

For years, many people suffering a stroke have not been able to get a critical drug due to time limits on its use. Now, a new study suggests that treatment time window can be doubled.

Experts said the findings could open up the treatment option for many more stroke victims.

The drug is called tissue plasminogen activator, or tPA. It can dissolve the blood clot causing a pers...

Researchers say an experimental stroke drug prevented blood clots without the typical side effect of blood thinners: increased bleeding risk.

Bleeding is a common and potentially dangerous side effect of current anti-clotting drugs used to treat stroke patients. But the new findings suggest that the antiplatelet drug, called ACT017, may be a safe and effective alternative to current t...

For pregnant women, a C-section carries a higher risk of severe complications than a vaginal delivery, particularly after age 35, a new study finds.

The researchers said that cesarean deliveries appear to cause an overall 80% increased risk of severe maternal complications when compared with vaginal delivery.

For women 35 or older, the risk from C-section is nearly tripl...

A new version of an implantable heart pump could cut the risk of blood clots, bleeding and stroke in patients with advanced heart failure, according to a study funded by the device's maker.

The study included more than a thousand patients who received either Abbott Inc.'s HeartMate 3 left ventricular assist device (LVAD) or the HeartMate II.

After two years, about 75 percent...

Heart patients who get a stent to prop open a blocked artery are typically put on a powerful anti-clotting drug and aspirin for a full year after their procedure.

Now, new research suggests these patients can safely drop the aspirin regimen after just three months, and lower their bleeding risk in the process.

"Even though this treatment strategy needs to be confirmed in oth...

Overweight children may be more likely than normal-weight children to develop life-threatening blood clots as adults, a new Danish study suggests. The good news is, getting to a healthy weight by age 13 eliminated the extra risk.

For the study, published Friday in the Journal of the American Heart Association, the research team used medical exam records to calculate the annua...

If you're obese and you want to do your heart a favor, try adding some olive oil to your diet.

So suggests new research, which found that healthy but severely obese patients who ate olive oil at least once a week had lower platelet activation. That means their blood showed less propensity toward forming clots -- which might help lower their risk of heart attack or stroke.

But ...

High testosterone levels can drastically increase a man's risk of heart failure and stroke-causing blood clots, a new study reports.

Men with a genetic predisposition to high testosterone levels have a nearly eightfold increased risk of heart failure and twice the risk of thromboembolism (blood clots that can block veins or arteries leading to the brain or lungs), researchers found.

While it's long been understood that being overweight or obese raises the odds of stroke, new research indicates those carrying extra weight are far less likely to die after having such a "brain attack."

For the study, scientists analyzed more than 1,000 people who had a so-called ischemic stroke, in which a clot blocks blood flow to the brain. The researchers found that severely ob...

Keto, Paleo, Atkins -- there's no shortage of low-carb diets to try, but new research suggests that over time, living low-carb can raise your risk of a heart condition called atrial fibrillation, or a-fib.

People who regularly got fewer than 45 percent of their calories from carbohydrates were 18 percent more likely to develop a-fib than people who ate a moderate amount of carbohydra...

Taking the blood thinner Pletal (cilostazol) with either aspirin or clopidogrel (best known as Plavix) lowers stroke patients' risk of a subsequent stroke better than taking aspirin or clopidogrel alone, a new study finds.

The Japanese study was funded by Pletal's maker, Otsuka Pharmaceutical, and tracked outcomes for people with the most common form of stroke, ischemic stroke. These...

For patients who receive clot-busting drugs after a stroke, intensive blood pressure lowering is safe and it reduces their risk of bleeding in the brain, a new study finds.

Brain bleeds are a major potential side effect of clot-busting drugs. But the use of extreme blood pressure lowering to reduce that risk in patients who take the drugs after ischemic stroke has been controversial. ...

Newer blood thinners are recommended over warfarin for people with the heart condition called atrial fibrillation (a-fib) in updated treatment guidelines issued by three major American heart groups.

The newer drugs are called non-vitamin K oral anticoagulants (NOACs). Examples include dabigatran (Pradaxa), rivaroxaban (Xarelto) and apixaban (Eliquis). They don't require the same frequ...

There's a significant rise in the risk of heart attack and stroke in older people in the months before they're diagnosed with cancer, a new study finds.

"Our data show there is an associated risk of ischemic stroke and heart attack that begins to increase in the five months before the cancer is officially diagnosed, and peaks in the month just before," said study author Dr. Babak Navi...

A common heart rhythm disorder, atrial fibrillation, may speed up mental decline in older adults, new research suggests.

If you have atrial fibrillation, or A-fib, your heart beats irregularly. This means blood can pool and form clots that go to the brain, causing a stroke.

The good news from this study: Blood thinners can reduce the odds for stroke and maybe delay or preve...

A new study involving mice raises another concern about the danger of e-cigarettes in humans after experiments showed that short-term exposure to the device's vapors appeared to increase the risk of clot formation.

A higher risk of clots forming can lead to a greater chance of a stroke or heart attack.

In the study published July 18 in the Journal of the American Heart ...

Transwomen who undergo hormone therapy may face higher chances of blood clots, stroke and heart attack, a new study suggests.

The term transwoman refers to a woman who is designated male at birth. Some undergo hormone therapy to minimize their male characteristics and maximize female traits.

"While our study confirmed elevated risks of certain vascular events related to hor...

Blood transfusions around the time of surgery may raise your risk for dangerous blood clots, researchers report.

A new study of U.S. patients found that nearly 1 percent of those who received red blood cells before, during or after surgery developed clots in the following month.

Clot risk doubled after one transfusion and increased with additional transfusions -- tripling wi...

A new MRI scanning technique can help doctors better nail down when a person has suffered a stroke and whether clot-busting drugs will help preserve their brain.

This technique could save the brains of some people who suffer "wake-up" strokes, where symptoms become apparent after they wake from a night's sleep, said lead researcher Dr. Gotz Thomalla, a neurologist with the University ...

It's been long known that people who sit for extended periods of time run the risk of blood clots.

In fact, the condition has been dubbed economy class syndrome because it's believed it can be brought on by stretches of prolonged immobility on long-distance flights.

Now, a new study out of Japan found that people fleeing a natural disaster seemed to be at risk of the unexpec...

After a stroke, many patients are given the clot-busting intravenous drug alteplase, but another drug may be more effective, Australian researchers report.

Among more than 200 stroke victims, TNKase (tenecteplase) was about twice as effective as alteplase in restoring blood flow to the brain, and it also resulted in less disability, the scientists found.

"Tenecteplase is lik...

Those tangled blue varicose veins that can pop up on your legs as you age may be more than unsightly: New research suggests they might quintuple your risk of dangerous blood clots.

Known as deep venous thrombosis (DVT), these clots in the legs can be life-threatening if they travel to the lungs or heart, Taiwanese researchers said.

"Varicose veins are not merely a cosmetic o...

Hours spent binge-watching that hot new series might feel great, but it's doing no favors for your blood vessels, new research shows.

The study found that people who spend too much time in front of the TV are at increased risk for blood clots in their veins -- a condition called venous thromboembolism (VTE).

These clots, which often occur in the legs, can dislodge and trave...

Good old aspirin is just as effective as newer, expensive drugs at preventing blood clots after hip or knee replacement, a new clinical trial suggests.

Researchers said the findings could change some doctors' prescribing habits.

After knee or hip replacement surgery, there's a risk of blood clots in the legs or lungs. So it's routine for patients to take clot-preventing drug...
