MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Heart failure (HF) is a chronic condition and progressive disease which is associated with a high-risk of hospitalization and death. One of the principle ways in which heart function is estimated is the use of ultrasound to calculate the ejection fraction of the heart, an estimate of the heart’s pump function. The ejection fraction can help predict how long patients will live and affects decision-making with regards to what medications may help their condition.
A total of 39,982 patients from 254 hospitals who were admitted for Heart failure between 2005 and 2009 were included. They were followed over time to see if they were admitted to the hospital again or if they died during this period. We compared three subgroups within this large group of patients based on their estimated ejection fraction. Across subgroups, the 5-year risk of hospitalization and death was high when compared with the U.S. population. Furthermore, the survival for patients with a diagnosis of heart failure who have been hospitalized once for this condition have a similarly poor 5-year risk of death and re-hospitalization, regardless of their estimated ejection fraction.
