pressure/resistance ventricles must overcome to eject blood through semilunar valves into peripheral blood vessels

New cards
preload
the degree of myocardial fiber stretch at end of diastole
55
New cards
stroke volume
amount of blood ejected by L vent during each contraction
56
New cards
ECG
info about cardiac troubles
57
New cards
ankle brachial index
measurement of arterial insufficiency based on ratio of ankle vs brachial systolic pressure
58
New cards
RAAS
renin >angiotensin 1>angiotensin 2(vasoconstrictor controlling aldosterone(aldosterone reabsorb Na. Sodium retention prevents fluid loss and increases blood volume and BP
59
New cards
If BP is up then renin should be
down because reduced arteriolar pressure usually inhibits renin secretion
60
New cards
Atherosclerosis
involves formation of plaque within arterial vessel wal;
61
New cards
Risk factor for athersclerosis
Diabetes
62
New cards
Athersclerosis cause
blood vessel damage> inflammation> plaque forms obstructing blood flow
63
New cards
Unstable plaque
more severe possible blood vessel blockage
64
New cards
PAD
result of systemic arthersclerosis
65
New cards
Inflow obstruction
involve distal end of aorta and the common internal and external iliac artery
