T/F: Echo is not useful for the detection of coronary artery disease?

False

role for echo continues to increase in CAD, specially with the expanded role of stress echo
The electrical aberration that would produce a sawtooth pattern in an M-mode scan of the mitral valve

LBBB (left bundle branch block)
RBBB (right bundle branch block)
Wolff-Parkinson White syndrome
atrial fibrillation

atrial fibrillation

in A fib, each P wase generates an atrial contractions resulting in a constant reopening of the mitral valve that gives a sawtooth appearance
T/F: Early systolic "beaking" of the IVs is noted on M-mode with:

RBBB
LBBB
electrical pacing
Type B Wolff-Parkinson-White

F,T,T,T

RBBB does not have the same effect on the LV conduction as LBBB or Wolff-Parkinson. If electrical pacing is done in the RV apex, beaking can bee seen.
Atherosclerosis is a disease that begins in the

adventitia
intima
transverse fibers
inner media
outer media

intima
T/F: Which of the following are true regarding atherosclerosis

is a specific disease
usually develops at bifurcation
is a segmental disease
is a generalized disease
intimal damage/repair may begin in adolescence

F,T,F,T

atherosclerois is a generalized disease that begins most often at bifurcations b/c of the shear forces generated at the wall surfaces. Px with atherosclerosis in the periphery will have other atherosclerotic changes in the carotid & coronary vesssels even though these may be clinically silent. Of all of the theories of its development, the injury/repair cycle seems to best account for the prevalence of coronary ather disease found on postmortem exam of young mell killed in Vietnam, Regardless of its etiology there is no quesiton that disruption of intimal continuity is the principal manisfestation
In pathogenesis of thromboembolism, which of the following is likely to occure first?

loss of intimal continuity
aggreagation of platelets and fibrin
fibrinoplatelet embolic shower
development of fibrosis
plaque hemorrhage

loss of intimal conitnuity
Which of the following is NOT considered a risk factor for atherosclerosis?

hypertension
being female
diabetes mellitus
lipoprotein abnormalities
tobacco use

being female

being a female is not considered a risk factor although postmenopausal females are at greater risk for atherosclerosis than premenopausal females
