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).

Cardiac rehab after VAD implantation rare—but effective

Only 30 percent of Medicare patients who received ventricular assist devices (VADs) in 2014 attended cardiac rehabilitation, but those patients enjoyed significant decreases in hospitalizations and mortality over the following year, according to a study in JACC: Heart Failure.

Guideline adherence—not patient volume—linked to better heart failure care

A new analysis in Circulation suggests low-volume centers that follow clinical guidelines are able to provide the same level of care in treating heart failure as higher-volume centers.

Wearable patch successfully assesses patients' heart failure status

A wearable patch with the ability to track cardiac activity can assess patients’ heart failure status, researchers reported in Circulation: Heart Failure this week.

Adult heart disease could stem from fetal infections

Heart disease in adults could be a result of fetal infection and inflammation before birth, especially if a baby is born prematurely, researchers from the University of Washington School of Medicine reported this week.

Researchers ID risk of heart failure subtypes by gender, race

Men are more prone to develop heart failure with reduced ejection fraction (HFrEF) than women but both sexes are equally likely to have heart failure with preserved ejection fraction (HFpEF), according to research published Jan. 19 in Circulation.

Moms face increased risk of HF for 6 weeks post-delivery

A six-week period following delivery poses the greatest threat to a new mom’s heart health, according to a study published this month in Circulation—it’s during these 42 days postpartum that a woman appears most susceptible to heart failure.

Genetic variants could be key to identifying chemo-induced cardiotoxicity

As life expectancy continues to expand for cancer patients, clinicians are increasingly dealing with oncological complications like cardiotoxicity, according to a medical team in the Netherlands—and those doctors are met with a paucity of research on the topic.

JACC publishes expert consensus document to guide clinicians’ treatment of HFrEF

An update on the 2013 heart failure guidelines released jointly by the American College of Cardiology and the American Heart Association, the new decision pathway aims to guide clinicians through 10 critical issues in treating heart failure with reduced ejection fraction (HFrEF).
