Magnetic Resonance Imaging in Patients With Cardiac Implantable Electronic Devices With Abandoned Leads

Abstract Full Text
JAMA Cardiol. Published online February 17, 2021. doi:10.1001/jamacardio.2020.7572

This cohort study assesses if the performance of magnetic resonance imaging in the presence of an abandoned cardiac implantable electronic device lead is safe and whether there are deleterious effects on concomitant active cardiac implantable electronic device leads.

Time to Clinical Benefit of Dapagliflozin and Significance of Prior Heart Failure Hospitalization in Patients With Heart Failure With Reduced Ejection Fraction

Abstract Full Text
JAMA Cardiol. Published online February 17, 2021. doi:10.1001/jamacardio.2020.7585

This secondary analysis of a randomized clinical trial examines the timing of the onset of clinical benefit with dapagliflozin and its magnitude as a function of proximity to prior heart failure hospitalization in patients with chronic heart failure with reduced ejection fraction.
