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).

Hospitals improve adherence to heart failure guidelines regardless of teaching status

From 2005 to 2014, hospitals participating in the Get With The Guidelines (GWTG) program improved their adherence to heart failure performance measures, according to a database analysis.

These U.S. cities have the lowest rate of reported heart attacks

High resting heart rate, blood pressure linked to poor mental health

Many mental health disorders are co-morbid with abnormalities in heart function and blood pressure. A new study from the University of Helsinki sought to determine if problems with heart rate and resting blood pressure precede psychiatric illness.
