One month of clot prevention after a stent was as effective as year-long course for AFib

Research Highlights: A one-month course of dual clot-preventing therapy followed by a single clot-prevention medication for the remainder of the standard 12-month regimen in adults with atrial fibrillation (AFib) who received a coronary stent was as effective as one year of continuous dual therapy for preventing stroke, heart attack and death. Participants treated with the one-month regimen experienced fewer bleeding problems than those in the year-long dual-treatment group. This is the first study to suggest the one-month strategy is as safe and effective as the standard year-long regimen of dual clot-preventing therapy for people with AFib treated with a stent.

Ablation reduces stroke risk for AFib and may remove need for some types of blood thinners

Research Highlights: Successful catheter ablation resulted in a low risk of stroke associated with atrial fibrillation (AFib), a type of irregular heart rhythm, according to an international study. Researchers said these findings may suggest that ongoing blood-thinning medication may not be needed after an ablation procedure. While catheter ablation is known to reduce the occurrence of AFib, it’s been unclear if it also reduces the increased stroke risk associated with the AFib. Note: This ...

Earlier blood transfusion may reduce heart failure, arrhythmia in adults with heart disease

Research Highlights: Earlier blood transfusion after major surgery – when hemoglobin was below 10 g/dL rather than beow 7 g/dl - did not affect the risk of severe complications, such as death, heart attack, need for a heart procedure, kidney failure or stroke. However, the timing of the blood transfusion may be associated with a lower risk of irregular heartbeat and heart failure among people with heart disease, according to a new study of U.S. military veterans. Note: This trial is simultaneously published today as a full manuscript in the peer-reviewed scientific journal JAMA. Embargoed ...

Diabetes drug reduced irregular heartbeat events in overweight/obese adults with AFib

Research Highlights: Adults with atrial fibrillation and obesity/overweight (but no diabetes) who took the diabetes medication metformin after a rhythm correction procedure were more likely to stay free of AFib episodes for a year. Weight loss was not thought to be the main reason metformin helped, since there was only a modest weight change among those taking the medication. Future studies may compare the impact of metformin with other diabetes medications in treating adults with obesity and AFib. Note: The study featured in this news release is a research abstract. Abstracts presented at American Heart Association’s scientific meetings are not ...

Cup of coffee a day may not be harmful for some adults with AFib and could lower episodes

Research Highlights: During the 6 months after treatment to restore a normal heart rhythm, adults with atrial fibrillation (AFib) who were randomly assigned to drink coffee every day were 39% less likely to have a recurrence of AFib compared to participants assigned to not have any coffee or other caffeinated drinks. The results of the 200-person trial may challenge the common belief that caffeine may spur more abnormal heart rhythms such as AFib. Researchers say it is reasonable for health care professionals to let their AFib patients try naturally caffeinated drinks ...

Investigational daily pill lowered bad cholesterol as much as injectables

Research Highlights: For people who have experienced a heart attack or stroke, or who are at high risk of one and need further cholesterol lowering, a new daily pill may be a more convenient yet similarly effective option to injectable therapies. The oral medication, enlicitide, lowered LDL cholesterol by up to 60% and could eventually offer an option for people whose LDL levels remain above goal despite lifestyle changes and standard cholesterol medications like statins. A longer, ongoing cardiovascular outcomes study will examine whether enlicitide can reduce the risk of heart attack or stroke. Note: The study featured ...

Medication still better than procedure for some irregular heartbeat conditions

Research Highlights: Standard care, which included medication for those eligible, was better than a promising minimally invasive procedure for people with irregular heart rhythms who had high stroke and bleeding risk. The procedure seals off a small pouch of heart tissue, where most blood clots form in people with irregular heartbeat. However, in older people, standard care, including the use of blood thinners when indicated, did a better job at prevention of stroke, blood clots, cardiovascular or unexplained death ...

Understanding how bacteria use “sunscreen” to adapt to climate

Cyanobacteria, commonly known as blue-green algae, are found almost everywhere in the world—from hot springs to arctic ice to antioxidant smoothies. Part of their extreme adaptability lies within a unique light-harvesting structure called the phycobilisome. These modular antennae both collect energy from sunlight, and adapt to changing light levels in order to provide a sort of sunscreen for the bacteria. One important way that phycobilisomes adapt involves an accessory protein to both sense and protect against too much light. ...

Patients with peripheral arterial disease who also have atrial fibrillation face significantly higher risk for cardiac events including death

New research from Intermountain Health in Salt Lake City finds that patients diagnosed with peripheral arterial disease (PAD) who also have atrial fibrillation (AFib) face a significantly higher risk of major adverse cardiovascular events (MACE). The Intermountain study analyzed long-term data of Intermountain Health patients with PAD and found that AFib was present in approximately one in four PAD patients, making this combination far more common than previously recognized. More importantly, Intermountain researchers found the presence of AFib nearly doubles the risk of major adverse cardiovascular events in patients compared to PAD alone. Irregular heart rhythms are called arrhythmias. ...

Factoring in frailty and age to improve pancreatic cancer treatment

While some risk factors for cancer can be mitigated through lifestyle choices such as diet or exercise, aging is not one of them. In the case of pancreatic cancer, it also can limit treatment options if a patient is too frail to be safely treated with surgery or other alternatives. Scientists at the NCI-Designated Cancer Center at Sanford Burnham Prebys Medical Discovery Institute would like to expand options for these patients with personalized treatments. Many stand to benefit from a therapeutic strategy that factors in age. The average age of a patient diagnosed with pancreatic cancer is 70, and nearly two-thirds of cases are in people over the age of ...

Exploring how the maternal bond affects social processing in babies

In a new JNeurosci paper, Sarah Jessen and colleagues, from the University of Lübeck, explored how infants track their mothers’ voices compared to unfamiliar voices. The researchers also explored whether this vocal processing affects how babies process new faces. Brain recordings of babies around 7 months old showed that they were far more attuned to the voices of their mothers than strangers. Additionally, neural tracking of unfamiliar faces was stronger when babies heard a stranger’s voice compared to their mother’s voice at the same time. Whether a face ...

How do people learn new movement patterns and alternate between them?

In a new JNeurosci paper, Kahori Kita and colleagues at Johns Hopkins University explored how people switch between intuitive motor skills they know and newly learned movement patterns. Study volunteers frequently made errors switching between more innate movements and new ones. These errors were largely because people persistently stuck to the movement patterns they used before the switch. Notes Kita, “People made similar errors when switching from the intuitive to the new skill, as when switching from the new skill to the intuitive one.” A second group of people learned two new movement-based skills. It was initially even more difficult for these ...
