Special MRI scan could identify stroke risk in people with atrial fibrillation
Atrial fibrillation is a heart rhythm disorder that affects millions of people. It can make you feel lousy. Even worse, it can cause potentially disabling or deadly strokes. A special MRI scan may — I stress the “may” — help identify people with atrial fibrillation who are at high risk of having a stroke. This could help many people with this condition to avoid taking warfarin or other clot-preventing medications for life.
A normal heartbeat starts in a cluster of cells called the pacemaker. It sits in the heart’s upper right chamber (the right atrium). These cells generate a pulse of electricity that...

Impact of atrial fibrillation on stroke risk eliminated with multiple risk factors
Dr Benn Christiansen said: "We know that atrial fibrillation increases the risk of ischemic stroke. And in patients with atrial fibrillation or previous ischemic stroke, the risk of stroke increases with the number of risk factors. But until now, little attention has been paid to the association between stroke risk and risk factors in patients without prior stroke or atrial fibrillation. We wanted to explore that association and to quantify if stroke risk was of comparable size in patients with numerous risk factors...

Blocked Heart Arteries May Presage Stroke
Even if you are considered to be at low risk for stroke, having blocked heart arteries can mean you are more likely to have one, says new research published online this week in Stroke, a journal of the American Heart Association. The researchers suggest blocked arteries should be taken into account to the same extent as other known risk factors such as atrial fibrillation when assessing patients' stroke risk. Lead author Dirk M. Hermann is professor of vascular neurology and dementia at the University Hospital Essen in Germany...

New Risk Assessment Tool To Predict Stroke In Patients With Atrial Fibrillation
A more accurate and reliable stroke prediction model has been developed to help physicians decide whether to start blood-thinning treatment for patients with atrial fibrillation, as described in the current online issue of the Journal of the American Heart Association. Atrial fibrillation affects millions of Americans. Because the heart-rhythm disturbance promotes the formation of blood clots that can travel to the brain and block an artery, atrial fibrillation independently increases the risk of ischemic stroke four-to-five-fold...

One-year data from global atrial fibrillation (AF) registry show antithrombotic agents not optimally used to prevent stroke
One-year outcomes data from the first cohort of the Global Anticoagulant Registry in the FIELD (GARFIELD), an innovative, independent academic research initiative, provide insights into the elevated stroke risk among subpopulations of patients with atrial fibrillation (AF). The findings, from eight abstracts presented this week at the ESC Congress 2013, collectively show that anticoagulant therapy - which is known to significantly lower stroke risk in AF patients - is consistently under-utilised among those at-risk AF patients...

Prolonged monitoring increases AF yield in stroke survivors
Another presentation at the International Stroke Conference today shows that prolonged periods of Holter-ECG monitoring markedly increase detection of paroxysmal atrial fibrillation in patients with stroke.

Pulse monitor 'will pick up thousands of stroke risk patients'
Patients with a type of heart palpitation that can raise the risk of stroke fivefold will be spotted thanks to a new type of blood pressure monitor, doctors hope.

Stroke risk 'higher at start of warfarin treatment'
Conclusion
This study has found that warfarin was associated with an increased risk of ischaemic stroke during the first 30 days of treatment. After 30 days of treatment, warfarin was associated with a decreased risk of stroke.
However, this study has a number of limitations that should be considered:
All information was from patient records, which means that it wasn't subject to recall bias, but the information may not be complete – we do not know if, for example, people took the medication they were prescribed.
There may be other factors (confounders) that explain the association seen. In particular, the ba...

Stroke Down to Fifth-Leading Killer in U.S. -- Here's What the Statistical Change Really Means
In the 1970s, Joseph Broderick was a resident at the Mayo Clinic in need of a focus for his fellowship. He decided to give stroke research a try.
Part of the lure was all the unanswered questions, like: Who is most likely to have a stroke? Why do they have it when others seemingly like them don't? Is stroke getting more or less common? What can be done to prevent it?
Another part of the lure was a landmark study on the frequency of stroke being done in the hospital's hometown of Rochester, Minnesota. Being part of it meant working for one of the nation's leading stroke researchers at the time, Jack Whisnant.
By the mid-...

10 steps to lower stroke risk
More than two dozen factors influence the odds of having a stroke. Some can't be changed, like getting older or having a family history of stroke. But a surprising number of these factors can be controlled, even when an underlying medical condition further ups the risk of stroke, reports the August 2013 Harvard Heart Letter.
"Stroke is potentially one of the most devastating illnesses that we see, and it's especially tragic when simply taking good care of one's blood pressure or some other preventive measure might have averted it," says Dr. Thomas Lee, MD, co-editor in chief of the Harvard Heart Letter.
There are two basic...

Check the pulse to track irregular heartbeats after a stroke
The rapid, irregular heartbeat known as atrial
fibrillation is a key cause of stroke. New research suggests that it's to blame
for more strokes than doctors realized, and that simply measuring the pulse could
help detect unrecognized atrial fibrillation and avert a second stroke, reports
the October 2014 Harvard Heart Letter.
Atrial fibrillation can come and go,
lasting from a few seconds to several days. Some people have distressing
symptoms such as palpitations, dizziness, or chest pressure. For many others, atrial
fibrillation passes silently. Either way, blood can pool in the heart's upper
chambers, or atria. This stag...

Sepsis-driven atrial fibrillation and ischaemic stroke. Is there enough evidence to recommend anticoagulation?
Sepsis can lead to cardiac arrhythmias, of which the most common is atrial fibrillation (AF). Sepsis is associated with up to a six-fold higher risk of developing AF, where it occurs most commonly in the first 3 days of hospital admission. In many patients, AF detected during sepsis is the first documented episode of AF, either as an unmasking of sub-clinical AF or as a newly developed arrhythmia. In the short term, sepsis that is complicated by AF leads to longer hospital stays and an increased risk of inpatient mortality. Sepsis-driven AF can also increase an individual ' s risk of inpatient stroke by nearly 3-fold, comp...
