Heart Failure

Heart failure occurs when the heart cannot pump as much blood as the body requires. This ineffective pumping can lead to enlargement of the heart as the myocardium works harder pump the same amount of blood. Heart failure may be caused by defects in the myocardium, such as an a heart attack infarct, or due to structural issues such as severe heart valve regurgitation. Heart failure can be divided into HF with preserved ejection fraction (HFpEF), and HF with reduced ejection fraction (HFrEF). The disease is further divided into four New York Heart Association (NYHA) classes. Stage IV heart failure is when the heart is completely failing and requires a heart transplant or hemodynamic support from a left ventricular assist device (LVAD).

Video games may motivate heart failure patients to exercise more

Heart failure patients who were given instructions on how to use a Nintendo Wii device—which incorporates physical activity into video gaming—improved their exercise capacity and quality of life more than counterparts who were simply advised to exercise 30 minutes per day.

New Study Demonstrates Feasibility of Using RenalGuard-Guided Diuretic Therapy for Acute Heart Failure Patients

MILFORD, Mass. — May 29, 2018 — RenalGuard Solutions™, Inc., a medical device company focused on innovative fluid management technologies for the cardiac and vascular markets, today announced new clinical study results demonstrating the feasibility of using RenalGuard®-Guided Diuretic Therapy to optimize fluid management in Acute Decompensated Heart Failure (ADHF) patients while alleviating related symptoms.

Social isolation in HF patients related to increased risk of death, use of healthcare resources

Patients with heart failure who describe themselves as being socially isolated have an increased risk of death and also have an increased use of healthcare resources, according to new research published in the Journal of the American Heart Association on May 23.

Machine learning algorithm predicts survival for heart transplant candidates

Researchers from the University of California Los Angeles (UCLA) have developed a new algorithm which better predicts pre- and post-heart transplant survival than existing methods.

Beta-blockers equally effective for blacks, whites with HFrEF

A study published May 8 in the Journal of the American Heart Association suggests black and white patients with heart failure with reduced ejection fraction (HFrEF) derive similar benefit from beta-blockers, despite conflicting previous reports.

His bundle pacing trumps right ventricular approach in single-center study

A His bundle pacing (HBP) strategy was associated with a significant reduction in hospitalizations for heart failure when compared to pacemaker implantation via the right ventricle, according to a study published online May 14 in the Journal of the American College of Cardiology.
