Atrial Fibrillation News and Research

RSS

Atrial fibrillation (AF) is the most common arrhythmia. An arrhythmia is a problem with the speed or rhythm of the heartbeat. A disorder in the heart’s electrical system causes AF and other types of arrhythmia. AF occurs when rapid, disorganized electrical signals in the heart’s two upper chambers, called the atria, cause them to contract very fast and irregularly (this is called fibrillation). As a result, blood pools in the atria and isn’t pumped completely into the heart’s two lower chambers, called the ventricles. When this happens, the heart’s upper and lower chambers don’t work together as they should. Often, people who have AF may not even feel symptoms. However, even when not noticed, AF can lead to an increased risk of stroke. In many patients, particularly when the rhythm is extremely rapid, AF can cause chest pain, heart attack, or heart failure. AF may occur rarely or every now and then, or it may become a persistent or permanent heart rhythm lasting for years.

New findings reveal the long-standing underrepresentation of women in cardiology leadership roles

In a trio of studies analyzing trends in cardiology research funding, clinical trials and leadership, Johns Hopkins Medicine researchers say some progress has been made in the gender gap that has long favored men, but inequalities persist and are likely linked to ongoing disparities in outcomes for women with heart disease.

Novel transcatheter repair system for tricuspid regurgitation shows promising results at one year

Patients with tricuspid regurgitation, a common and debilitating form of valvular heart disease, who received a novel investigational device intended to repair the defective valve experienced significant improvements in blood flow through the heart and in quality of life at one year, according to research presented at the American College of Cardiology's 71st Annual Scientific Session.

Implantable heart rhythm monitor does not benefit NSTEMI patients

Patients who received an implantable heart rhythm monitor after suffering a heart attack did not have fewer subsequent cardiovascular events overall, but a subset of patients whose heart attack was classified as non-ST segment elevation myocardial infarction (NSTEMI) did see strong benefits, in a study presented at the American College of Cardiology's 71st Annual Scientific Session.

Extension study shows mavacamten’s efficacy and safety in treating hypertrophic cardiomyopathy

Use of mavacamten, a novel cardiac myosin inhibitor, to treat people with symptomatic obstructive hypertrophic cardiomyopathy (HCM), a condition that results in excess thickening of the heart muscle, resulted in continued benefits in patient quality of life and outcomes over an extended period of time, according to interim data from the EXPLORER-HCM extension study presented at the American College of Cardiology's 71st Annual Scientific Session.

Leakage after left atrial appendage occlusion associated with higher risk of adverse events

Patients who had leakage to the left atrial appendage due to incomplete device sealing after left atrial appendage occlusion (LAAO) experienced more clotting and bleeding events within a year following their procedure compared with patients who had no leaking, according to a study presented at the American College of Cardiology's 71st Annual Scientific Session.

Smartwatch application can be used for atrial fibrillation screening

Atrial fibrillation (AFib) was confirmed in nearly 94% of people who were initially identified to have signs of the heart rhythm disorder by a smartwatch application and who followed up with a clinician, in a study presented at the American College of Cardiology's 71st Annual Scientific Session.

'Stroke-heart syndrome' may put stroke survivors at higher risk for future cardiovascular events

People who survive an ischemic stroke are much more likely to develop major heart complications during the first month after their stroke, and, as a result, they also have an increased risk of death, heart attack or another stroke within five years, compared to people who don't develop heart problems soon after a stroke, according to new research published today in Stroke, the peer-reviewed, flagship journal of the American Stroke Association, a division of the American Heart Association.

Reduced kidney function caused by antithrombotic therapy can influence bleeding events

Antithrombotic therapy is prescribed to prevent thrombotic (blood clotting inside a blood vessel) events but the treatment also increases the likelihood of experiencing a bleeding event, which can be extremely serious if it occurs in a vital organ.
