Researchers presented data and clinical updates at the Heart Rhythm Society Annual Scientific Sessions in San Francisco.
Live coverage from the Cardiology Today team featured news from the conference, onsite video interviews with leading experts and research implications on patient care and practice.
Healio Internal Medicine presents the six most-viewed stories from HRS 2016.
Among warfarin users, patients with AF at increased risk for dementia
In patients taking warfarin long-term, those with atrial fibrillation had elevated risk for dementia, according to a presentation.
Although mechanisms behind the association between dementia and AF are unknown, researchers previously found an increased risk for dementia in patients with AF when treated with warfarin with low percentage of time in therapeutic range (TTR) compared to patients that had high percent TTR.

Successful AF ablation reduces health care costs
Patients with atrial fibrillation who are event-free after catheter ablation had a 40% reduction in their health care costs, according to presented data.
Among those patients, health care expenditures dropped from a mean of $24,781 in the year before ablation to $14,823 after ablation (P < .001). Read more.
RESPOND-CRT: Hemodynamic sensor technology safe, effective for patients with HF, CRT devices
A new technology using a hemodynamic sensor is safe and effective to enhance response to cardiac resynchronization therapy in patients with HF, according to presented data.
The response rate for patients assigned the novel lead was 75% vs. 70% for patients with echocardiographic optimization (P < .001). Read more.
EFFORTLESS: Subcutaneous ICD effective in treating ventricular tachyarrhythmias
The subcutaneous implantable cardioverter defibrillator successfully treats ventricular tachyarrhythmias without lead failure or endocarditis, according to EFFORTLESS registry data.
The device had an inappropriate shock rate for AF/supraventricular tachycardia comparable to conventional ICDs, researchers reported. Read more.
Smartphone-based ECG monitor effective for diagnosing palpitations
A smartphone-based ECG recorder was noninferior to an ambulatory event monitor for the diagnosis of palpitations, according to results of a prospective study.
“The biggest takeaway from this study is how technology can literally diagnose palpitations,” Deepika Narasimha, MD, of University at Buffalo, told Cardiology Today. Read more.
VIDEO: Michael R. Gold, MD, PhD, highlights groundbreaking trials at HRS 2016
New data presented at the Heart Rhythm Society Annual Scientific Sessions advance the understanding of catheter ablation and cardiac resynchronization therapy, President-Elect Michael R. Gold, MD, PhD, told Cardiology Today.
Gold, from the Medical University of South Carolina and co-chairperson of the late-breaking clinical trials session, highlights three trials in this video exclusive: VANISH, RESPOND-CRT and the MultiPoint Pacing IDE study. Watch here.
