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).

Omega-3 slashes GI bleeding rates for LVAD patients

Omega-3 treatment was associated with significantly fewer gastrointestinal bleeding events for patients with left ventricular assist devices (LVADs), researchers reported in Circulation: Heart Failure.

AFib’s impact on heart failure outcomes varies by subtype

Higher ejection fractions (EFs) among heart failure patients are associated with an increased incidence of atrial fibrillation (AF) and worse cardiovascular outcomes, according to data from a multinational European registry.

Why Cleveland Clinic began screening carpal tunnel patients for cardiac amyloidosis

Cleveland Clinic researchers identified amyloid deposits in 10.2 percent of patients undergoing carpal tunnel release surgery, suggesting biopsies of hand tissue could be an early signal of life-threatening cardiac amyloidosis.

Prior cardiotoxicity linked to 30% increased risk of CHF during pregnancy

Women with a history of cardiotoxicity from previous cancer treatments are around 30 percent more likely to experience clinical congestive heart failure (CHF) before, during or after pregnancy, according to research published ahead of print in the Journal of the American College of Cardiology.

Researchers develop 1st mini pacemaker capable of long-term mouse studies

Harvard Medical School scientists have created a wirelessly programmed, miniaturized pacemaker which functions for weeks to months at a time, opening the door to “previously impossible investigations of arrhythmia and heart failure in the mouse.”
