contraindications of Exercise TEst
|
stroke
MI unstable angina wheezing HF, etc |
|
|
In dynamic exercise....
|
HR increases
Diastole gets shorter SV increases CO increases SVR decreases increase in oxygen extraction CO redistribution from inactive areas to active areas |
|
|
normal vs CAD ex. test
|
Normal: HR goes higher, SBP goes higher, exercise longer, stop bc muscle ache, ST shifts are rare
CAD: stop bc chest pain SOB, or fatigue, ST seg shifts are more common but not everyone |
|
|
REsting BF
|
before exercise
|
|
|
peak or maximum flow
|
during maximum stress
|
|
|
Stress ECG reading
|
CAD: ST segmetn lower (depression), elevation can also occur, reflect ischemia 10:1 dep to elevation
|
|
|
Bayesian Theorem
|
postive test: likely to be false pos with a low pre test liklihoood
negative test; likely to be false neg in pt with high pre test liklihood of disease |
|
|
METS
|
measure of how much O2 body uses
|
|
|
imaging methods combined with stress tests
|
Nucelar testing
Echo MRI |
|
|
Pharmocologic stress test w/imaging for obese or non exercise pts
|
vasodilators, if CA blocked, flow wont increase; more powerful than exercise
inotropes(dobutamine): used in pateints with bronchospasm from vasodilator use |
