An Electronically Delivered Patient-Activation Tool for Intensification of Medications for Chronic Heart Failure With Reduced Ejection Fraction: The EPIC-HF Trial.

Background: Major gaps exist in the routine initiation and dose up-titration of guideline-directed medical therapies (GDMT) for patients with heart failure with reduced ejection fraction. Without novel approaches to improve prescribing, the cumulative benefits of heart failure with reduced ejection fraction treatment will be largely unrealized. Direct-to-consumer marketing and shared decision making reflect a culture where patients are increasingly involved in treatment choices, creating opportunities for prescribing interventions that engage patients.

An Electronically delivered, Patient-activation tool for Intensification of medications for Chronic Heart Failure with reduced ejection fraction: Rationale and design of the EPIC-HF trial.

Background: Heart failure with reduced ejection fraction (HFrEF) benefits from initiation and intensification of multiple pharmacotherapies. Unfortunately, there are major gaps in the routine use of these drugs. Without novel approaches to improve prescribing, the cumulative benefits of HFrEF treatment will be largely unrealized.

Efficacy of echocardiographic screening of pilot applicants.

Background: The efficacy of cardiac screening programs for individuals in competitive athletics and high-risk occupations such as commercial and military aviation continues to be highly debated. For the past 12 yr, all United States Air Force (USAF) pilot applicants have undergone screening echocardiography.

Methods: All available studies were reviewed for disqualifying (DQ) diagnoses.

H2O2 activates Nox4 through PLA2-dependent arachidonic acid production in adult cardiac fibroblasts.

Stimulated production of reactive oxygen species (ROS) by plasma membrane-associated nicotinamide adenine dinucleotide phosphate oxidases (Nox) in non-phagocytic cells regulates a number of biological processes including growth, vessel tone, and oxygen sensing. The purpose of this study was to investigate H(2)O(2)-stimulated ROS production in primary adult cardiac fibroblasts (CF). Results demonstrate that CF express an H(2)O(2)-inducible oxidant generating system that is inhibitable by diphenylene iodonium (DPI) and sensitive to antioxidants.
