QUESTIONS AND CORRECT ANSWERS (VERIFIED
ANSWERS) | A+ GRADE
CAD Risk Factors: Non-modifiable - ✔✔ANSWER✔✔-age
genetic disposition
family history
ethnic background
gender
CAD risk factors - ✔✔ANSWER✔✔-Age >55
male
fam hx
personal hx peripheral vasc/Cerebrovascular disease
smoking
lipid abnorm
DM
HTN
obesity
sedentary
cocaine
,estrogen use
dyslipidemia - high LDL, low HDL, high triglycerides
what happens when LDL becomes oxidized - ✔✔ANSWER✔✔-becomes
oxidized when exposed to endothelial cells and smooth muscle cell
then exposed to macrophages
becomes foam cell
makes up atherosclerotic plaque
what does HDL do - ✔✔ANSWER✔✔-reverse cholesterol transport
returns excess cholesterol from the tissue to the liver where it binds to hepatic
receptors and is processed or eliminated as bile or converted to cholesterol-
containing steroids
protects LDL from oxidation
explain the relationship of lipoprotiens and diabetes as a risk factor for CAD -
✔✔ANSWER✔✔-lipoproteins can be altered by glycation as a result of high
glucose levels which causes a greater integration into macrophages (engulf
oxidized LDL) this then accumulates in the arterial wall causing platelet
aggregation and smooth muscle proliferation
android obesity - ✔✔ANSWER✔✔-excess body fat that is placed
predominantly within the abdomen and upper body, as opposed to the hips
and thighs
strongest link with CAD risk r/t insulin resistance, decreased HDL levels,
increased blood pressure, and inflammation
9 P21 - ✔✔ANSWER✔✔-genetic variant associated with a strong risk for CAD
,what is the risk of having an MI in relation to the age that it occurred in a
parent - ✔✔ANSWER✔✔-inverse relationship
if you have a parent who had an MI at 40 you have a higher risk than someone
who's parent had one at 70
Women typically present with CAD symptoms 10 years earlier than men
t/f - ✔✔ANSWER✔✔-false
lipoprotein (a) and CAD - ✔✔ANSWER✔✔-nontraditional risk factor
associated with atherosclerosis and thrombosis
genetically derived particle
at risk for premature CAD as well as stroke
elevated high sensitivity c reactive protein and CAD (hs-CRP) -
✔✔ANSWER✔✔-acute phase reactant or protein
made in liver
indirect measure of atherosclerotic plaque-related inflammation/progression
inflammatory marker
the more inflammation the more likely to have plaque ruptures
t/f lipoproteins increase risk for a cardiac event, thrombus, and stroke -
✔✔ANSWER✔✔-true
t/f high numbers of large and puffy LDL particles are associated with increased
risk for CAD - ✔✔ANSWER✔✔-false
high numbers of small dense LDL
, total cholesterol levels - ✔✔ANSWER✔✔-desirable - <200
Borderline - 200-239
high - >240
LDL levels - ✔✔ANSWER✔✔-Optimal: <100
Near optimal: 100-129
Borderline high: 130-159
High: 160-189
Very high: >190
Triglycerides levels - ✔✔ANSWER✔✔-desirable - <150
borderline - 150 - 199
high - 200-499
very high - >500
HDL levels - ✔✔ANSWER✔✔-low - <40
high - >60
response to injury hypothesis - ✔✔ANSWER✔✔-Atherosclerosis hypothesis
where plaque build up begins with the endothelial damage
changes in permeability
monocytes attach
move in
release oxygen free radicals
LDL becomes oxidized
monocyte becomes macrophage
