Heart's pumping function is not an indicator of heart failure survival rates

(University of California - Los Angeles Health Sciences) Contrary to popular practice, a measure of the heart's pumping function known as 'left ventricular ejection fraction' is not associated with the long-term outcomes of hospitalized heart failure patients, a UCLA-led study of Medicare patients has found. Hospitalized heart failure patients in all age groups within the study and with all levels of ejection fraction had significantly lower rates of survival after five years and a higher risk o...
