A client diagnosed with systolic heart failure is admitted to the intensive care unit (ICU). When planning care for this client which does the nurse understand about systolic heart failure?
A) Occurs when the ventricle fails to contract adequately to eject a sufficient volume of blood into the arterial system.
B) Results when the heart cannot completely relax in diastole, disrupting normal filling.
C) Decreases passive diastolic filling, increasing the importance of atrial contraction to preload.
D) Results from decreased ventricular compliance caused by hypertrophic and cellular changes and impaired relaxation of the heart muscle.
Answer: A
Heart failure is commonly classified as either systolic or diastolic heart failure, based on the underlying pathology. Systolic heart failure occurs when the ventricle fails to contract adequately to eject a sufficient volume of blood into the arterial system. All other choices are true of diastolic heart failure, not systolic.
