lesson 11 part 1 Flashcards
heart failure is also known as _____
congestive heart failure
a clinical syndrome characterized by signs and symptoms of ‘‘fluid overload or of inadequate tissue perfusion’’
heart failure
the inability of the heart to pump sufficient blood to meet the needs of the tissue
heart failure
there is a problem in the CONTRACTION of the heart
systolic dysfunction
there is a problem in the FILLING of the heart
diastolic dysfunction
most often a progressive, life long condition that is managed with lifestyle changes and medications
heart failure
heart failure is classified in tow types:
LHF
RHF
occurs when the ‘left ventricle cannot effectively pump blood’ out of the ventricle into the aorta
pulmonary congestion
when the right ventricle fails, congestion in the peripheral tissues and the vicera
right heart failure
increase venous pressure leads to
JVD / jugular venous distention
what stage: patients with HIGH RISK for developing left ventricular dysfunction but “WITHOUT STRUCTURAL HEART DISEASE or symptoms of heart failure”
STAGE A
what stage: patients WITH left ventricular or structural heart disease and HAS NOT developed symptoms of heart failure
STAGE B
what stage: patients WITH left ventricular or structural heart disease and WITH CURRENT or prior symptoms of heart failure
STAGE C
what stage: patients WITH REFRACTORY END STAGE heart failure requiring specialized interventions
STAGE D
results in decreased blood volume being ejected in the venthen retricle
systolic hf
the sympathetic nervous system produces?
epinephrine and norepinephrine
if there is a decrease in renal perfusion, it cause _____
renin release
the renin promotes the formation of ______
angiotensin 1
angiotensin 1 to angiotensin 2 is converted by _______
ACE
it is the primary cause of heart failure
atherosclerosis
CAD is found in more than ___ of the patients with HF
60%
it deprive hearts cells of oxygen
ischemia
