T/F

ischemic disorders typically affect arteries only
TRUE
which artery supplies the left lateral wall of the left ventricle?
left circumflex artery of the left coronary artery
where do the coronary arteries originate?
aorta- just above aortic valve
which artery supplies the left ventricle?
ant descending artery of left coronary artery
which artery supplies the ant portion of the rt ventricle

a) anterior circumflex
b) interventricular A
c) marginal A
d) None
marginal artery of the rt coronary artery
the posterior descending artery of the coronary artery supplies the

a) post HT
b) R ventricle
c) left ventricle
d) all
e) none
posterior portion of ht
which artery supplies the ant portion of the HT?

a) Ant descending
b) Left Coronary A
c) Ant interventricular
d) Rt Coronary A
e) a, b
f) b, c
Ant interventricular of the left coronary artery
T/F

blood flow to the HT muscle is greatest during systole
F

DIASTOLE- valve is closed therefore it must enter the coronary system instead of being circulated thru the body
if you increase the aortic pressure what happens to the blood flow to the HT muscle?

a) increase blood flow
b) decrease blood flow
c) stays the same
decrease blood flow- hi prssr more difficult to move
which of the following is false about blood flow to the HT muscle?

a) depends of vascular tone
b) regulated by metabolic need
c) affected by HR
d) can be compensated by collateral circulation
e) all are false
f) all are true
All true
also- depends on aortic prssr, is maximal during diastole
inadequate blood supply and inefficient metabolite removal defines

a) Myocardial infarction
b) Congestive Ht Failure
c) Ischemic Ht Disease
d) None
ischemic Ht disease- affects arteries
the possible causes of Ischemic Ht disease
atherosclerosis
vasospasm
thrombosis
aortic stenosis
which of the following is false about angina

a) it is a constricting pain
b) can radiate to the Left arm, shoulder, jaw, back
c) intensity decreases with time
d) all are true
e) all are false
intensity of pain INCREASES with time- telling body there is more potential damage

(pseudo aneurism - pain decreases)
T/F

classic angina is associated with atherosclerosis
True
classic angina - aka - exertional angina
with classic angina pain is related to

a) increased metabolic need
b) vasospasm
c) atherosclerosis
d) a, b
e) a, c
f) b,c
atherosclerosis
increased metabolic need

(vasopsasm = variant angina, unstable angina also caused by atherosclerotic plaque)
which of the following is not associated with atherosclerosis

a) classic angina
b) variant angina
c) unstable angina
d) all are associated
variant angina= due to vasospasm during rest or minimal exercise. it occurs at night and is cyclic
list the criteria for unstable angina
new onset < 2 months
symptoms occur at rest and last <20 min
exertional angina increases in severity
what is the most common cause of AMI?
rupture/fissure of atherosclerotic plaque- causes ischemia within minutes
transmural MI affects _____ layers
subendocardial MI affects _____
transmural- all layers of Ht are damaged- most life threatening

subendocardial- only layer below endocardium is damaged
ischemic damage is irreversible within
a) immediately
b) 10-20 min
c) 20-40 min
d) 1 hour
20-40 min
T/F

ischemic damage travels from outside to inside
F

inside to out
what are the three zones of ischemic damage
necrotic (inner most)
injured
suffering (outer most)
T/F

AMI can be relieved by Nitroglycerine supplement and rest
F

Narcotics are required
list manifestations of AMI
nausea, vomit,
fatigue, weakness,
anxiety, restless,
pale, cool moist skin,
tachycardia, hypotension, shock
following AMI- EKG diagnosis will detect _____
arrhythmia
Which of the following is/are not used as a diagnostic tool for MI

a) serologic marker
b) xray
c) Doppler
d) EKG
xray
doppler
following a MI, what happens to myoglobin levels

a) peak within 4-8 hours
b) normalize within 2-3 days
c) peak within 3-6 days
d) a, b
e) none
(elevate within an hour) peak 4-8 hours

(elevated CK/MB normalize within 2-3 days)
(LDH peaks within 3-6 days)
How long does it take Myoglobin levels to elevate following MI

a) 30 min
b) 1 hour
c) 3 hour
d) 4 hour
1 hours
what is the treatment plan following MI
rapid re-canalization of occluded coronary artery

relieve pain
manage life threatening complications
rehab to maximize physiologic/psychologic wellbeing
what is the treatment for MI

a) recanalize coronary artery
b) relieve pain
c) physiologic/psychologic rehab
d) all of the above
e) none
ALL
T/F

cardiac troponin levels increase following MI
TRUE- not helpful info in emergency situation
which serologic marker elevates within 4-8 hours and normalizes 2-3 days later after MI

a) myoglobin
b) CK/MB
c) LDH
d) Troponin
e) None
CK/MB
which serologic marker elevates within 24-48 hours and peaks 3-6 days later after MI

a) myoglobin
b) CK/MB
c) LDH
d) Troponin
e) None
LDH
