An ejection fraction of under 20 percent is frightfully low as far as survival…or is it?
“Having a low ejection fraction (absolute number) is not necessarily correlated to symptoms,” begins Pilar Stevens-Cohen, MD, FACC, Department of Cardiology, South Nassau Communities Hospital.
“For example, a person with an ejection fraction of 40 may be more symptomatic than one with an ejection fraction of 15.
“However, having systolic heart failure with an ejection fraction < 35, there is an increased mortality related to poor cardiac output and arrhythmias.
“Medication and ICD therapy when indicated may help manage symptoms and prevent arrhythmias; however, the mortality is still high.”
ICD stands for implantable cardioverter defibrillator.
“The biggest correlation with heart failure deaths is related to hospital admissions and renal failure/injury.
“Patients with renal failure and more than three hospitalizations in one year may have a mortality rate (one year) of >50 percent.”
