Flashcards in Cardiac Failure Deck (26)
What is cardiac failure?
cardiac output is insufficient for body's needs
usual cause of cardiac failure?
reduced systolic function
what does reduced systolic function lead to?
low ejection fraction
Cardiac output is determined by?
Direction of hydrostatic?
out of capillary
direction of osmotic?
Four causes of edema?
Increased venous pressure,
decreased osmotic pressure,
What causes increased cap permeability?
what causes blocked lymphatics?
what causes Increased venous pressure,
what causes decreased osmotic pressure,
plasma protein loss
increased Left Atrial venous pressure leads to?
increased Right atrial venous pressure leads to?
Renin-Angiotensin-aldosterone system does what?
overall fluid retention to maintain cardiac output
what Is the role of the sympathetic nervous system in cardiac failure?
increased noradrenaline, long term is bad
4 causes of shortness of breath?
on examination, what's a big sign that it's cardiac failure?
what causes Cor Pulmonale?
Heart Failure due to Lung Disease: COPD, CF, pulmonary fibrosis, PE
What is the ejection fractions for left heart failure?
40-50% = mild
30-40% = moderate
<30% = severe
if normal systolic ejection fraction but still has SOB?
diastolic heart failure,
poor compliance of ventricle
3 examples of cardiac failure due to incrsed body needs?
how come high arterial pressures don't cause oedema?
cause of step down of pressures to arterioles/metarterioles
List the causes of congestive heart failure/CCF?
2 kinds of pericardial disease?
1. pericardial tamponade
2. pericardial constriction
how do you get cor pulmonale?
long standing pulmonary fibrosis, CF, COPD, astha
