Congestive Heart Failure:
Definition and Symptoms
? Definition: The inability of the heart to meet the
metabolic (bloodflow) demands of the body at
normal ※filling pressures.§
? Diminished bloodflow causes symptoms of fatigue,
especially with physical activity.
? Elevated pressures in the heart contribute to fluid
retention in the lungs, abdomen and legs.
Function of the Heart
? The heartbeat, or cardiac cycle, has two phases
每 Systole 每 pumping the blood to the body
每 Diastole 每 receiving blood from the veins in preparation for
the next beat
? In congestive heart failure, both phases are often
abnormal
每 Systolic dysfunction 每 diminished amount of forward flow
每 Diastolic dysfunction 每 blood can*t get into the heart
normally in preparation for the next beat
