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).

Myocarditis remains difficult to diagnose, treat

Since 2005, the mortality from myocarditis has decreased, although it remains a difficult disease to treat and diagnose, according to a recent review.

Avoiding hypertension, obesity, diabetes by mid-life may reduce heart failure risk

A pooled analysis of four cohort studies found that patients who did not have hypertension, obesity and diabetes by 45 to 55 years old had up to an 86 percent lower risk of developing heart failure during their lifetime.

Behave yourself: Good heart habits save lives

Genetics isn’t the only determinant of heart disease. Healthy habits can decrease the risk of developing issues later in life. 

AHA 2016: CMS’s 30-day heart failure readmission rates do not help predict clinical outcomes

A registry analysis found that the quality of care and one-year clinical outcomes for Medicare beneficiaries were similar at centers with low and high risk-adjusted 30-day heart failure readmission rates.

AHA 2016: Investigational device notifies clinicians of worsening heart failure

After one year, the HeartLogic heart failure diagnostic service helped alert healthcare professionals of worsening heart failure in patients with cardiac resynchronization therapy defibrillator (CRT-D) systems, according to a multicenter, nonrandomized trial.
