CONGESTIVE HEART FAILURE Flashcards
1
Q
insufficient CO required by the metabolic demands of the organs
A
CHF
2
Q
mechanisms that maintain function?
A
frank starling mech hypertrophy neurohumoral systems -norepi -renin-angiotensin-aldosterone system -ANP
3
Q
physiologic results?
A
forward failure:decreased CO
-poor perfusion
backward failure
-congestion of venous system
4
Q
two types of CHF?
A
left sided
right sided
5
Q
common cause of left sided CHF?
where so they manifest?
A
ischemic heart disease
hypertension
atrioventricular/mitral valve disease
non-ischemic myocardial disease
heart
lung- backward failure
kidney, brain- forward failure
6
Q
common cause of left sided CHF?
where so they manifest?
A
left sided heart failure
pulmonary disease (cor pulmonale)
-pulmonary edema
-pulmonary effusion
venous congestion passive congestive hepatosplenomegaly peripheral edema ascites minimal pulmonary congestion
