Electrophysiology & Arrhythmia


For nearly 6,000 patients with heart failure and chronic kidney disease (CKD), the use of an implantable cardioverter defibrillator (ICD) showed no mortality benefit but a higher risk of subsequent hospitalizations after covariate adjustment, researchers reported in JAMA Internal Medicine.

Catheter ablation was associated with significantly fewer deaths and hospitalizations for worsening heart failure than medical therapy in a randomized trial of patients with atrial fibrillation (AFib) and heart failure.

A pair of researchers at Utah State University are aiming to revolutionize the world of digital monitoring with a new technology that can measure a person’s heartbeat using nothing more than a video camera and specialized software, the university announced Monday.

Atrial fibrillation (AFib) patients face higher odds for short-term cancer diagnoses but, depending on how long they've had AFib, the could face lower odds for cancer in the long run, a January study states.

Nearly half of all out-of-hospital cardiac arrest (OHCA) survivors struggle to rejoin the workforce and participate in society post-heart attack, a study published in Circulation: Cardiovascular Quality and Outcomes suggests.

Innovations in heart tech: 5 things standing between now and better medical technology

From pocket-sized electrocardiograms to watches that measure blood glucose levels, the field of medical technology is rapidly evolving. But these innovations, though oftentimes successful, aren’t necessarily living up to what scientists want them to be, according to presenters at the American Heart Association’s Scientific Sessions 2017.

AHA presentations highlight gender, racial disparities in response to cardiac arrest

Men are more likely to receive bystander cardiopulmonary resuscitation (CPR) in public locations than women and are more likely to survive cardiac arrest in those situations, according to research presented Nov. 11 at the American Heart Association’s (AHA) scientific sessions in Anaheim, California.

New LAA closure device linked to reduced stroke risk in pilot study

A new left atrial appendage (LAA) closure device can be implanted with a high success rate and slashes the one-year risk of stroke in nonvalvular atrial fibrillation (NVAF) patients, according to the researchers of the device’s pilot trial.

Deliver information in a nice, neat package for AFib patients

Millions of words have been written about communication—in relationships, in business partnerships, in patient-physician interactions. (How many of those words have been read is another question.) But an axiom for effectively conveying a thought or a feeling is that it’s not just what you say, it’s also how you say it.

Updated CPR guidelines recommend dispatcher instruction, rescue breaths for children

More cardiac arrest victims will survive if emergency medical dispatchers give cardiopulmonary resuscitation (CPR) instructions over the phone and if infants and children receive rescue breaths in addition to chest compressions, according to updated CPR guidelines released Nov. 7 by the American Heart Association (AHA).

TCT 2017: PREVAIL's Watchman is effective, but not '1st-line therapy' for AFib

A meta-analysis of the PREVAIL and PROTECT AF trials, two studies aimed at evaluating the efficacy of left atrial appendage closure (LAAC) with the Watchman device in atrial fibrillation (AFib) patients, ultimately found that LAAC with Watchman provides stroke prevention for nonvalvular AFib patients comparable to warfarin, with additional decreases in major bleeding events and mortality. The 5-year findings were presented at the 29th annual Transcatheter Cardiovascular Therapeutics convention in Denver.

Blood thinners cut dementia risk in AFib patients by 48%

Patients with atrial fibrillation (AFib) who are treated with blood thinners are at a significantly reduced risk for developing dementia, according to research published Oct. 24 in the European Heart Journal. Individuals on oral anticoagulants (OACs) at baseline demonstrated a 29 percent lower risk of dementia compared to those not on blood thinners, while people treated with OACs throughout the study experienced a 48 percent risk reduction.

Extroverts have better cardiovascular responses to stress

Extroverts benefit from lesser physiological responses to, more complete recovery from and better adaptation to social stressors, according to a new study published in Psychophysiology—a phenomenon that could have a range of cardiovascular health perks.

Moderate drinkers at no increased risk for AFib later in life

While heavy drinkers are at an established, increased risk for developing atrial fibrillation (AF) due to their alcohol habits, light-to-moderate consumers are at virtually no increased likelihood of developing the condition, a study out of Nord-Trøndelag County in Norway has found.
