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).

HeartWare’s alignment guides prompt another recall

The FDA announced another Class I recall for HeartWare, this time citing damaged alignment guides or connection pins in its ventricular assist system that potentially could cause the pump to stop. The recall affects 1,763 devices.

Congestion in heart failure patients is associated with increased mortality risk

Patients with acute decompensated heart failure who had severe congestion during and after hospitalization had an increased risk of mortality and morbidity, according to a post-hoc analysis of two clinical trials.

CRT-D in older adults improves survival compared with ICD alone

After one and four years, older patients with heart failure were more likely to be alive if they received cardiac resynchronization therapy with defibrillator (CRT-D) compared with a group who received only an implantable cardioverter-defibrillator (ICD), according to a registry analysis.

Hospice care referral for heart failure leads to lower hospital readmissions

Medicare beneficiaries who were hospitalized for heart failure were less likely to be readmitted within 30 days if they were referred to hospice care, according to an analysis of data from Alabama hospitals. Within six months of hospital discharge, most of the patients who had died were not referred to receive hospice care.

Hospitalization, death rates high for HF patients with preserved ejection fraction

Nearly one-third of patients who were hospitalized with heart failure with preserved ejection fraction died during a follow-up period of 49.5 months, according to a randomized study.

HRS.15: Baroreflex activation therapy improves quality of life in heart failure patients

BOSTON—A novel approach known as baroreflex activation therapy led to a 30 percent improvement in New York Heart Association  classification and an increase in quality of life among patients with heart failure and reduced ejection fraction who had failed previous therapies.

FDA issues another recall for HeartWare

The FDA issued a Class I recall on a component of the HeartWare Ventricular Assist System. This latest recall targets a splice repair kit that fails when exposed to excessive force.

Data shows the CardioMEMS HF System adds incremental benefit when combined with device therapy and is cost effective

St. Jude Medical, Inc., a global medical device company, today announced important new data presented during the Heart Rhythm Society's (HRS) 36th annual Scientific Session supporting improved outcomes and cost-effectiveness of the CardioMEMS™ HF System for the management of Class III heart failure patients.
