Gated F-18 FDG PET for assessment of left ventricular volumes and ejection fraction using QGS and 4D-MSPECT in patients with heart failure: a comparison with cardiac MRI.

PLoS ONE, 2014
PurposeVentricular function is a powerful predictor of survival in patients with heart failure (HF). However, studies characterizing gated F-18 FDG PET for the assessment of the cardiac function are rare.

Ventricular voltage‐gated ion channels: Detection, characteristics, mechanisms, and drug safety evaluation

Clinical and Translational Medicine, 2021
Cardiac voltage‐gated ion channels (VGICs) play critical roles in mediating cardiac electrophysiological signals, such as action potentials, to maintain normal heart excitability and contraction.

Sorted Golden-step phase encoding: an improved Golden-step imaging technique for cardiac and respiratory self-gated cine cardiovascular magnetic resonance imaging

Journal of Cardiovascular Magnetic Resonance, 2019
Background Numerous self-gated cardiac imaging techniques have been reported in the literature. Most can track either cardiac or respiratory motion, and many incur some overhead to imaging data acquisition.

Cardiac monitoring in HER2-positive patients on trastuzumab treatment: A review and implications for clinical practice

Breast, 2020
Trastuzumab prolongs progression-free and overall survival in patients with human epidermal growth factor receptor 2 (HER2) positive breast cancer. However, trastuzumab treatment is hampered by cardiotoxicity, defined as a left ventricular ejection ...

Unscheduled Emergency Visits after Cardiac Devices Implantation: Comparison between Cardioverter Defibrillators and Cardiac Resynchronization Therapy Devices in less than one year of Follow Up

Arquivos Brasileiros de Cardiologia, 2019
Background: The use of Cardiovascular Implantable Electronic Devices (CIED), such as the Implantable Cardioverter Defibrillator (ICD) and Cardiac Resynchronization Therapy (CRT), is increasing. The number of leads may vary according to the device.
