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.

Change in AFib risk score predicts stroke better than single measurement

Analyzing the change in stroke risk factors for atrial fibrillation (AFib) patients was far more powerful in predicting stroke than assessing baseline risk factors alone, researchers reported in the Journal of the American College of Cardiology.

MRIs proven safe for patients with FDA-unapproved implantable devices

Longtime claims that heart patients fitted with implantable cardiac devices should forgo MRI testing for safety concerns could be incorrect and “outdated,” according to new research published in the New England Journal of Medicine.

Recent study evokes memories of sudden cardiac death in basketball players

When writing about a recent JAMA Cardiology study, I was struck by an image of former Loyola Marymount University basketball star Hank Gathers swinging from the rim after a powerful dunk—and then collapsing to the court seconds later. Gathers died at 23.

Injectable MRI tech could redefine way cardiologists detect CVD

New technology developed at New York’s Binghamton University could change the way clinicians detect heart disease with MRI scans, research published in the journal Colloid and Surfaces B: Biointerfaces suggests.

Positive stress ECG proven to predict cancer death

A positive echocardiogram (ECG) stress test can predict not just cardiovascular mortality but also death due to cancer, a team of Italian researchers reported this week in the Journal of the American Heart Association.

Abnormal ECGs common in NBA players; more research required to pinpoint athletes at risk

Even with criteria modified for athletes, National Basketball Association (NBA) players are more likely than other athlete groups to have abnormal electrocardiographic (ECG) findings, according to a report in JAMA Cardiology.

AFib patients more likely to die in rural hospitals

Patients with atrial fibrillation (AFib) who are admitted to rural hospitals have a 17 percent increased risk of death during their stay compared to those admitted to urban facilities, researchers reported in HeartRhythm.

Time for action to improve bystander response to cardiac arrest

Recent research provided sobering news on Americans’ ability to respond to cardiac arrest, which has about a 10 percent survival rate when occurring outside the hospital, according to the American Heart Association (AHA).

Study supports longer arrhythmia detection intervals for single-chamber ICDs

Patients with single-chamber (VVI) implantable cardioverter-defibrillators (ICDs) programmed with longer intervals for detecting arrhythmias experienced significant reductions in appropriate therapies, shocks and all-cause mortality when compared to patients with standardly programmed ICDs, according to a study published online Nov. 20 in JACC: Clinical Electrophysiology.

Athletes more likely to experience sudden cardiac arrest during racing, soccer, hockey

The incidence of young athletes experiencing sudden cardiac arrest during competitive sporting events is slim—just 0.76 cases in 100,000 athlete-years—but it does happen, according to one team of Canadian researchers who analyzed dozens of out-of-hospital cardiac arrests in an effort to dissect the underlying causes of these tragedies.
