A novel pacemaker designed to mimic a patient’s organic breath increased blood flow to the heart in a study of individuals with heart failure, according to research published in the journal Thorax.

Research that will be presented at the American Heart Association’s Resuscitation Science Symposium in Philadelphia this month suggests the National Institutes of Health invests far less money in cardiac arrest research than in research for other conditions, including diabetes, drug-use disorders and ischemic heart disease.

Taller people might be at an increased risk for atrial fibrillation, according to research set for presentation at the American Heart Association’s Scientific Sessions on Nov. 16.

The net clinical benefit of anticoagulants like warfarin and apixaban slows over time in patients with atrial fibrillation, according to a Circulation: Cardiovascular Quality and Outcomes study, diminishing as people age and face competing risks of death.

A Portland-area cardiologist has been accused of implanting more than 100 patients with unnecessary pacemakers, incentivized by free travel and gifts from device sales representatives, the East Oregonian reports.

Bystanders of out-of-hospital cardiac arrests are more likely to face legal consequences for delaying or failing to provide CPR than for damages incurred during a resuscitation attempt.

Nearly three-quarters of atrial fibrillation patients taking dabigatran remain adherent to the medication two years after filling their first prescription, while just over 25% discontinue the drug for various reasons, according to an analysis published in the American Journal of Cardiology.

The U.S. is seeing an uptick in the use of mechanical resuscitation devices despite a paucity of evidence that the digitized CPR tools are effective, researchers reported in JAMA Network Open this fall.

A cross-sectional study of heart patients undergoing ICD implantation revealed a marked decline in the use of defibrillation testing over time in the U.S., suggesting the precaution might be losing its value as a clinical tool.

A study of patients undergoing catheter ablation of atrial fibrillation between 2010 and 2015 found that early post-ablation mortality rates increased over the half-decade, reaching 1.35% per quarter by the end of the research period.

A novel machine learning algorithm improved patient selection for CRT in a study of nearly 1,000 heart failure patients, representing an opportunity to optimize care and spare certain individuals from a pricey procedure that might not benefit them.

Short-term opioid prescriptions could have long-term consequences for heart patients with cardiac implantable electronic devices, according to work published in Heart Rhythm Oct. 21.
