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.

Dual antithrombotic therapy reduces risk of major bleeding events in AFib patients undergoing PCI

Dual antithrombotic therapy combined with the blood thinner dabigatran and a P2Y inhibitor could be a more effective—and less risky—alternative to standard care in atrial fibrillation (AFib) patients undergoing percutaneous coronary intervention (PCI), a study published this month in the New England Journal of Medicine reports.

Abbott smartphone-compatible cardiac monitor gains FDA clearance

Abbott has received FDA clearance for its smartphone-compatible insertable cardiac monitor (ICM), the healthcare company announced Oct. 23. The device allows a patient to actively monitor his heart activity while giving physicians the ability to identify arrhythmias remotely.

Thyroid hormone levels tied to increased risk of AFib

Higher levels of thyroid hormone in the blood were associated with an increased risk of atrial fibrillation (AFib), even when the levels were within normal range, according to an analysis of 11 studies containing more than 30,000 people.

Icelandic researchers ID genetic variant that increases risk of AFib

Icelandic researchers have uncovered two novel genetic variants of atrial fibrillation (AFib), one of which could increase the risk of developing AFib for susceptible patients.

A large-scale study of nearly 80,000 patients suggests men develop atrial fibrillation (AFib) an average of 10 years earlier than women, according to researched from the American Heart Association.

New mobile apps for patients, healthcare providers work together to treat AFib

Heart experts have launched a pair of smartphone and tablet applications designed to treat atrial fibrillation (AFib), the most common cardiac rhythm disorder.

Researchers analyze long-term benefit, safety of ICDs in patients with Brugada syndrome

Patients with Brugada syndrome (BrS) benefit from implantable cardioverter defibrillators (ICDs) but are at significant risk of device-related complications, according to the longest-term study to date on the topic.

Low serum calcium levels associated with sudden cardiac arrest

Patients with lower levels of calcium in the blood are more likely to experience sudden cardiac arrest (SCA), according to a study in Mayo Clinic Proceedings.

Watching an intense hockey game could double your heart rate

Hockey fans with cardiac disease might want to watch their heart rate a little more closely this winter, a team of Canadian researchers advises.

Drug reactions with NOACs in AFib patients could result in major bleeding problems

Patients prescribed non-vitamin K oral anticoagulants (NOACs) to manage symptoms of atrial fibrillation (AFib) could be at increased risk for major bleeding if they are taking certain common medications at the same time, a study published in the Journal of the American Medical Association states.
