Q

greatest immediate improvement in patient outcomes associated with CAD

A

stop smoking

25
worst risk factor for CAD
diabetes mellitus
26
most common risk factor for CAD
hypertension (> 140/90)
27
age that is a risk factor for CAD
males > 45, females > 55
28
family hx of premature CAD which are risk factors for CAD
- 1st degree relative | - premature coronary disease in male relative < 55, female < 65
29
optimal values (mg/dL) for LDL, HDL, cholesterol
LDL 100-130 HDL M 40-50, F 50-60 Cholesterol < 200
30
most common ADRs of statins
muscle pain, liver damage
31
where is ST elevation located on EKG w/inferior wall MI ?
II, III, aVF
32
where is ST elevation located on EKG w/lateral wall MI?
I, V5, V6, aVL
33
where is ST elevation located on EKG w/anterior wall MI?
V2, V4
34
where is ST elevation located on EKG w/septal MI?
V1
35
if a patient has chest pain in the office, what is the next best test after EKG?
stress test - must be able to read EKG - must be able to exercise (85% of max HR = 220 - age)
36
what test should be done if patient has chest pain in office, EKG is performed, but EKG cannot be read w/stress test (LBBB, LVH, digoxin, pacemaker)?
- exercise echo - nuclear stress test (exercise and isotope uptake w/Tc99/sestamibi or thallium, which is picked up by normal myocardium)
37
what test should be done if patient has chest pain in office, EKG is performed, but patient cannot exercise w/stress test?
- dobutamine echo | - nuclear stress test (persantine/dipyridamole and isotope uptake w/thallium or Tc99/sestamibi)
38
what condition should persantine be avoided with?
asthma (b/c bronchospasm)
39
most accurate test for detection of CAD that determines narrowing of coronary arteries (70% indicates surgery)
coronary angiography
40
procedure that is best for ACS, especially w/ST elevation ; does NOT provide clear evidence for mortality benefit in STABLE patients
angioplasty (percutaneous coronary intervention)
41
next step in patient with normal EKG and want to r/o rhythm problem
holter monitor
42
process that involves continuous EKG monitoring in the hospital
telemetry
43
TIMI (thombolysis in MI) score
- > 65 y.o. - ASA in past 7 d. - angina 2x in last 24 hrs - CAD risk factors (HTN, DM, HLD, first degree relative w/MI M < 55, F < 65) - CAD history (> 50% stenosis) ST elevation of 0.5 mm - cardiac marker positive score of 7 indicates 41% greater chance of MI
44
what may cause false positive troponin levels (high troponin w/normal wall motion on echo)?
- CHF | - renal failure
45
compare rise, peak and duration of CK MB vs troponin
rise 3-4 hr, 1-2 hr peak 12 hr duration 1-2 days, 2 wks
46
within how many hours of chest pain must thrombolytics be used?
12 hours
47
fibrinolytic agent of choice in the U.S. ; as effective as alteplase and a decrease in risk of non-cerebral bleeding
Tenectaplase (TNK-tPA)
48
most widely used fibrinolytic agent worldwide - low cost, reasonable efficacy to safety ratio
streptokinase
49
number of diseased vessels indicated for angioplasty
1-2
50
number/diseased vessels indicate for coronary artery bypass graft (CABG)
3+, left main coronary a.
51
complications of coronary angioplasty
- restenosis - coronary a. rupture - hematoma at entry site
52
grafts used for CABG
- internal mammary a. (lasts 10 yrs) | - saphenous v. (lasts 5 yrs)
53
complications 2-3 days post-MI
arrhythmias (monitor pt in ICU)
54
major / comorbid complication 2-3 days post-MI
reperfusion arrhythmia - accelerated idioventricular rhythm (looks like v. tach, but not tachycardia) - BENIGN, DON'T TREAT
55
complications several days post-MI
- septal rupture - valve rupture GET ECHO (may need surgery and possible balloon pump)
56
what can all complications of MIs result in?
hypotension
57
how do you treat hypotension complication post-MI?
- repeat BP - trendelenberg position - fluids (250-500 mL NS over 30 min ; repeat q 15-30 min)
58
following steps for post-MI asymptomatic patient
- stress test - ACE inhibitor (best for anterior wall MI), ASA, beta blocker, clopidogrel - don't combine nitrates w/sildenafil or tadalafil (hypotension)
