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...

8 ways to prevent a stroke
This year, nearly half a million women will have a stroke. The June 2013 Harvard Women's Health Watch offers eight steps women can take to limit the chances a stroke will strike. Women can't do anything about two leading contributors to stroke—age and family history. But there are many other stroke risk factors they can control. Becoming aware of them is the first step. "Knowledge is power," says Dr. Natalia Rost, associate professor of neurology at Harvard Medical School and associate director of the Acute Stroke Service at Massachusetts General Hospital. "If you know that a particular risk factor is sabotaging your...

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...

Depression Could Double Stroke Risk In People Over 50
Published: May 13, 2015 04:35pm ET by LiveScience. People who have depression for a long time may be at increased risk for stroke, a new study suggests. Researchers found that adults ages 50 and older who had symptoms of depression that lasted more than two years were twice as likely to have a stroke in the following two years, compared with men and women of similar age with no signs of depression. "The exact pathway through which depressive symptoms may lead to stroke remains unclear, and is an important area for future research," said study lead author Paola Gilsanz, a postdoctoral fellow at the Harvard T.H. Cha...

Combination of a cholesterol-lowering statin and ezetimibe lowers risk of a heart attack or stroke
High cholesterol is a key culprit in the development of cardiovascular disease, the leading cause of death in the United States and many other developed countries. We know that lowering cholesterol helps prevent heart attacks and strokes. But an unanswered question remains: how low should you go? New research published online today in The New England Journal of Medicine suggests that lower is better. Cholesterol and cardiovascular disease Cholesterol travels through the bloodstream in two main particles: high-density lipoprotein (HDL) and low-density lipoprotein (LDL). HDL scavenges cholesterol from the bloodstream and fro...

Only the overworked die young
Follow me at @JohnRossMD Billy Joel was on to something. As the singer-songwriter suggested in “Movin’ Out,” working too hard really can give you a “heart attack-ack-ack…” And, as a recent study has also shown, stroke may be an even bigger problem than heart attack in people who are overworked. For the study, researchers from University College London compiled data on the relationship between working hours and heart attack risk in over 600,000 workers, as well as similar data on stroke risk in over 500,000 workers. They adjusted their data to compensate for individual workers’ differences due to healt...

Update on the SPRINT trial: Preliminary results pan out
In a previous blog, I reported on the preliminary results from SPRINT, a clinical trial that examined whether a systolic blood pressure target of 120 mm Hg or less would be better than a target of 140 mm Hg in patients with hypertension (high blood pressure). The National Heart, Lung, and Blood Institute of the National Institutes of Health issued a press release with the exciting results. Now, the full paper has been published in The New England Journal of Medicine, and the results appear to be as practice-changing at it initially seemed, demonstrating a stricter blood pressure goal can reduce the likelihood of dying. In ...

For the good of your heart: Keep holding the salt
Your doctor has probably told you to cut back on salt, especially if you have high blood pressure. For years we’ve understood that excess salt raises blood pressure and increases deaths from heart disease. The guilty element is sodium, which pairs with chloride to form common salt. So when the journal Lancet recently published a study reporting that low dietary sodium was associated with an increased risk of heart disease and death, controversy was predictable. A wealth of rigorous scientific studies supports a link between excess sodium intake and high blood pressure, heart attacks, and strokes. Yet the Lancet paper rep...

Daily low-dose aspirin can prevent heart attack and stroke but is often misused
Aspirin is often hailed as a wonder drug, thanks to its ability to help stave off heart attacks and clot-caused strokes. But fewer than half of people who could benefit from a daily low-dose aspirin take it, while many others take it when they shouldn't, reports the January 2014 Harvard Heart Letter. If you don't have heart disease, but do have high blood pressure, diabetes, or other risk factors for heart disease, don't automatically assume that taking aspirin every day is a good idea. "A lot of people take aspirin who really shouldn't," says Dr. Christopher Cannon, a cardiologist at Brigham and Women's Hospital and profe...

The SPRINT trial: A major advance in treating high blood pressure
This study was sponsored primarily by the National Heart, Lung, and Blood Institute of the National Institutes of Health. This trial is a wonderful example of the kind of long-term, large-scale clinical trials that are necessary to advance patient care meaningfully. The study results also illustrate the importance of randomized clinical trials — that is, studies in which patients are randomly assigned to one of two treatment arms. Lastly, credit must be given to the participants who consented to be enrolled in the study. They have generously and selflessly contributed to advancing medical science and improving the care o...

Strokes 'may be linked to temperature', study finds
Conclusion This retrospective study reports that there is an association between lower temperature and increased humidity and a slightly increased risk of ischaemic stroke. It was a large study, but there are several major limitations of this study design: The temperature was matched with discharge dates. There is a wide variation in the length of hospitalisation after a stroke, so the temperature at discharge may be very different to the temperature when the stroke occurred. The researchers assumed that changes in outdoor air temperature would have been experienced by all of the people who suffered from a stroke. It...

Could exercise be as effective as medication?
Conclusion The researchers found that there are very few trials that directly compare exercise with drug therapy for any condition. They were only able to find enough trials to be able to analyse results for four major conditions. They found that exercise reduced death rates for people after a stroke (although this analysis has limitations and should be interpreted cautiously), and that drug therapy with diuretics improved death rates for people with heart failure. They did not find any difference between exercise and drug therapy for death rates after a heart attack or in people with pre-diabetes. There were several limit...

Migraines linked to increased heart disease risk in women
Conclusion This study shows a strong link between migraine and cardiovascular disease, extending the link already found between migraine and stroke. However, many questions remain. We don't know if the results are relevant to men who have migraines, as all the people in the study were women. We also don't know if the results apply to non-white populations, as most of the women in the study were white. Previous studies on stroke have shown that the group at highest risk is who get an "aura" before a migraine – sensation(s) that tells them the migraine is on its way. But this study did not ask people about aura...

Atrial Fibrillation and Injected Aripiprazole: A Case Report
Conclusion In summary, although it is not possible to exclude confounding factors, the timing and dose-dependent effect of aripiprazole administration in our patient suggests an association between an initial intramuscular injection of long-acting aripiprazole and new onset of AF. This observation calls for clinical vigilance, not only in patients with additional risk factors for stroke but also in younger patients who might have predisposing factors for arrhythmias.
