Echo & stress test Flashcards
- assess general cardiac structure and function
- portable, low cost
TTE
- assess for endocarditis, cardiac source of embolus
- involves moderate sedation, semi-invasive
TEE
no known CAD, can exercise and has normal ECG
ETT
which is preferred, exercise or pharmacologic stress testing?
exercise
which is preferred: stress echo or stress nuclear?
echo
- assess viability, 3D relationships, HCM
- expensive and not readily available
Cardiac MRI (CMR)
2 main reasons to perform stress imaging
- ECG abnormalities at rest
- cant exercise adequately
these are C/I of what kind of testing
- Sick sinus syndrome
- High degree AV block
- Reactive airway disease (active wheezing)
- Significant carotid artery stenosis
vasodilator stress testing
these are C/I of what kind of testing
- Sick sinus syndrome
- High degree AV block
- Reactive airway disease (active wheezing)
- Significant carotid artery stenosis
vasodilator stress testing
these are C/I of what two testing
- Inability to exercise, gait instability
- Tachycardia
- Significant arrhythmia (ventricular tachycardia, high degree heart block)
- Aortic dissection or aneurysm
- ETT
- exercise nuclear imaging
what test does this apply to
Viability assessed by looking for delayed uptake of tracer in areas of the heart that are poorly perfused, but not dead
nuclear stress test
rarely used; calculate ejection fraction by comparing blood pool counts during systole and diastole
resting scan (MUGA)
4 indications for stress echo
- chest pain or dyspnea
- known or suspected CAD
- significance of known valve disease
- stress-induced pulmonary HTN
in addition to giving consent, list 5 other C/I to all types of stress testing
- MI < 1week
- unstable angina or ongoing chest pain
- decompensated HF
- hypertension or hypotension
- acute pulmonary embolism
these are 4 indications for what
- valvular issues
- intracardiac thrombus
- congenital abnormalities
- acute aortic pathology
