Congestive Heart Failure
Definition
a complex clinical syndrome that results from structural or functional impairment
of ventricular filling or ejection of blood, which in turn leads to the cardinal clinical
symptoms of dyspnea and fatigue and signs of HF, namely edema and rales.
Because many patients present without signs or symptoms of volume overload, the
term “heart failure” is preferred over the older term “congestive heart failure.”
the historical terms “systolic” and “diastolic” HF have been abandoned, and HF patients are now
broadly categorized into HF with a reduced Ejection Fraction (HFrEF; formerly systolic failure) or HF
with a preserved Ejection Fraction (HRpEF; formerly diastolic failure).
