Cards

Term
What do q waves indicate
Definition
past MI
Term
metabolic syndrome X
Definition
and combo of: HLD, HTN, CAD, glucose intolerance, DM, hyperuricemia

result of insulin resistance and obesity
Term
syndrome x
Definition
diff than metabolic syndrome x.
syndrome x is exertinal angina with normal coronary arteriogram, stress tests shows ischemia tho there are no coronary stenosises
Term
what is considered a + stress ECG
Definition
ST depression.
chest pain
hypotension
significant arryhtmia

(any of the above)
Term
what do you do if a pt has a + stress ECG
Definition
cardiac cath
Term
what % of coronary stenosis --> sx
Definition
70
Term
if a pt cant exercise what drugs can you use to induce a stress test
Definition
dobutamine
dipyramidole
adenosine
Term
medical therapy in CAD in general
Definition
ASA (reduces risk of MI)
BB (reduces frequency of coronary events)
nitrates (sx relief)
CCB (add on if still have sx after bb and nitrates)
Term
two surgery type of CAD
Definition
1. CABG
2. percut transluminal coronary angioplasty (PTCA)
Term
PTCA vs CABG
Definition
do PTCA if only 1-2 vessel disease
Term
major risks specific to ptca
Definition
restenosis (after 6 mo)
Term
pathophys of stable vs unstable angina
Definition
in unstable o2 demand is unchanged, there is just reduced resting coronary flow
in stable, there is issues when there is increased o2 demand
Term
medical tx in unstable angina
Definition
1. ASA
2. BB
3. Nitrates
4. LMWH or unfractionated heparin (enoxaparin)
5. gp11b/IIIa inhib (abciximab, tirofiban)
Term
variant prinzmetal angina features
Definition
1. vasospasm
2. with or without atherosclerotic leasion
3. angina at rest with ventricular dysryhthmias
4. ST elevation on ECG
Term
what does ST depression represent in variant angina?
Definition
transmural ischemia (subendothelial ischemia)
Term
medical tx of variant angina
Definition
CCB and nitrates more helpful in these pts
Term
first ekg change in MI
Definition
peaked t waves
very early on
often missed
Term
indication for tpa in pt with MI
Definition
st elevation in 2+ leads
Term
contra to tpa
Definition
uncontrolled htn (>180/110) can use after htn is controlled

active gi ulcers

previous stroke

recent surgery or invasive procedure

dissecting aortic aneyrsm

recent head trauma or traumatic cpr
Term
what are the only agents shown to reduce mortality in MI
Definition
BB
ACEI
ASA
Term
anterior MI changes in ekg
Definition
1. ST elevation or Q in V1-V4
(Q wave is a later change)
Term
posterior MI changes in ekg
Definition
1. large R in V1 and V2
2. ST depression in V1 and V2
3. big upright T in V1 and V2
Term
lateral MI changes in ekg
Definition
Q in I and aVL
Term
inferior MI changes in ekg
Definition
Q in II, III, aVF
