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).

Differences in hospitals' short-term heart failure mortality persist to 5 years

Heart failure patients treated at hospitals with lower 30-day mortality rates also enjoy a survival benefit one, three and even five years later, suggesting a short-term risk-standardized mortality rate (RSMR) may deserve additional weight in CMS’s financial incentive programs.

Baylor St. Luke’s reopens heart transplant program after review of patient deaths

Baylor St. Luke’s Medical Center in Houston reopened its heart transplant program June 15 after a two-week suspension in which the hospital conducted an internal review of two recent patient deaths.

Stem cell therapy for heart failure may save money, lives

Scientists are researching how to take stem cells from the patient’s blood to repair damage to the heart. A new therapy could reduce the need for operations, the U.K.’s Express newspaper reports, with researchers hoping the therapy could save lives while being cost effective. 

Progression of silent AFib tied to heart failure

Patients who progressed to having longer episodes of subclinical atrial fibrillation (SCAF) were more than four times as likely to be hospitalized for heart failure in a one-year span, according to a study published June 4 in the Journal of the American College of Cardiology.

Malnutrition aids in death prediction of heart failure patients

Measurements of malnutrition offer incremental prognostic value for patients with heart failure, but more work is needed to tease out which components of the condition are most crucial to calculate and treat, researchers reported in JACC: Heart Failure.

Average hospitalization for pediatric VADs costs $750K

The average hospital stay for pediatric patients requiring a ventricular assist device (VAD) spans nearly three months and costs $750,000, according to research in the Journal of the American Heart Association.

‘Home time’: A new outcome for heart failure trials?

Time spent alive and out of healthcare institutions can be calculated from claims data and represents an important, easy-to-grasp outcome for heart failure patients, researchers said.

Class I recall issued for Medtronic’s HeartWare VAD

The electrical connection between the ventricular assist device (VAD)'s power source and its controller may be interrupted due to oxidation on the connecting surfaces, according to the agency’s recall notice.
