Lecture 14: Cardiac Rehab Medical Conditions I Flashcards
What are the two main components of cardiac rehabilitation?
- Exercise
2. Patient Education
Why is patient education so important in cardiac rehabilitation?
It lets patients know what they can do - because being sedentary is the last thing someone with a cardiac problem should do
What are 5 general goals for a cardiac patient?
- Risk Factor Reduction
- Increase aerobic activity
- Return to safe vocational and recreational activities
- Decrease angina
- Decrease anxiety
When is aerobic activity (always involves overload) not indicated (in cardiac patients)?
After/during acute MI
What are the two most common complications for cardiac patients?
Depression and anxiety
What are some cardiac patients that we will see (5)?
- MI
- CABG
- Transplant
- Valve Replacement
- patients at risk for MI
What are the phases of cardiac rehabilitation (4 + 1 in between phase)? What are the timelines for each phase?
- Inpatient (2 days post event - discharge from the hospital)
- Transitional (immediately after hospital discharge to until outpatient program begins)
- Outpatient (1-3 weeks post event to ~3 months after event)
- Transitional - short term weaning from outpatient to lifetime self-management
- Lifetime - 3 months post event to the remainder of the life of the patient
What should you work on with the patient in the Phase I after MI? (5)
- Patient Education
- Exercise guidelines
- Risk factor reduction
- Teaching home exercise Rx
- Low level exercise (< 3 METs)
What are the factors that the patient must be taught during patient education in Phase I after post MI?
Having the patient self record HR, BP and RPE.
Why is teaching a patient to monitor RPE so important during phase I post MI?
RPE may be the most accurate representation of the patient’s effort during activity (because medication can disrupt both BP and HR)
How intense should exercise be during phase I post MI?
Low level exercise (<3 METs, 2-4 times per day, 5-7 days per week)
If indicated, what (6) activities can be used during the inpatient phase (phase I)

Can you include resistance exercise during the outpatient phase (phase III)?
Yes, but monitor HR and BP changes carefully
What are the safety guidelines of the outpatient phase (phase III) for HR?
Stay within target HR training range
Keep 10 bpm less than ischemic threshold HR
What is the formula to finding the target HR range?
HR reserve formula:

- ETT (GXT)
There is a second transitional phase after the outpatient phase (phase III). What is this phase also known as?
The weaning phase
There is a second transitional phase after the outpatient phase (phase III). What is the purpose of this phase?
It is a short term weaning phase that transitions the patient from supervised outpatient to lifetime self-management
