Cardiac Rehabilitation Flashcards
what is cardiac rehabilitaiton?
a multidisciplinary approach to the rehabilitation of pts w/heart disease
involves:
- education
- structured, progressive physical activity
- lifestyle modification
- vocational counseling
Candidacy for Cardiac Rehabilitation
- Post MIs
- Post cardiac surgery, including transplants
- Heart disease
- CHF
- Post PTCA
- Elderly
- Asymptomatic, at-risk patients
Who is not a candidate for Cardiac Rehab?
- Unstable Angina
- hemodynamic instability
- Serious arrhythmias
- Conduction abnormalities (2nd and 3rd degree blocks)
- active infections
- uncontrolled diabetes
- resting ST segment depression
what constitutes hemodynamic instability?
SP > 200
DP > 100
orthostatic fall > 20 mmHg
does cardiac rehab work?
YES!
- reduces body weight
- unloads the heart
- improves cardiac function
- might get changes in lifestyle
- modifies risk factors
List and briefly describe the 4 phases of cardiac rehab
- Phase I → acute/inpatient phase
- immediately upon becoming medically stable
- monitored
- Phase II → subacute/rehab/ conditioning phase
- immediately upon D/C
- monitored
- Phase III → training/intensive rehab
- outpatient
- Phase IV → maintenance
what is a standard outcome measure for Phase II Cardiac Rehab?
6-min walk test
what occurs in the initial assessment in Phase I cardiac rehab?
- Hx
- family interview
- Physical exam
- How well can pt perform ADLs
- ROM, Strength, Gait
- Sternal precautions
how is exercise tolerance determined in Phase I cardiac rehab?
- monitor BP 3-5 min
- pt is slowly walked 25-30 ft and a rest break is taken
- if no unusual HR, BP, or ECG reading observed then the walk is repeated and over time lengthened according to pt’s subjective feelings as well as vitals
- activity is progressed as long as pt tolerates the exercise
Describe treatment within Phase I cardiac rehab
- start slowly
- use short duration sessions, multiple times per day
- warm up/cool down
- intensity
- <120 bpm or <20-30 bpm increase over resting
- symptom monitor
when would you stop treatment in Phase I Cardiac Rehab?
- unusual HR increase
- inappropriate BP response
- SP >210
- DP> 110
- 10 mmHg or more drop in DP w/exercise → stop exercise
what symptoms call for a cessation of exercise in Phase I Cardiac Rehab?
- angina
- dyspnea
- excessive fatigue
- mental confusion or dizziness
- pallor, cyanosis, cold sweat
- EKG abnormalities
- arrhythmias
Goals for Phase I cardiac rehab
- initiate return to IADLs
- counteract the deleterious effects of bed rest, reduce risk of thrombi and pneumonia, maintain muscle tone, reduce OH
- provide medical surveillance during ADL types of activities
- pt/family edu
activities to consider for phase I cardiac rehab
- self care
- arm and leg AROM
- very light weights
- independent transfers
- bedside sitting to ambulation to stairs
how many METS should be attainable by D/C from Phase I cardiac rehab?
3-5 METS
ADLs = ______ METS
about 5 METS
length of Phase II cardiac rehab
8-12 weeks
goals of Phase II cardiac rehab
- improved exercise tolerance
- pt edu
- risk factor reduction/secondary prevention
- return to work
- promote psychological, behavioral and educational improvement
- 9-10 METs or 3.0 mph for 30 min
how is intensity determined in Phase II cardiac rehab?
via a fraction of HR reserve
HRmax = 207 - ((0.7) * age))
things to consider when establishing intensity in phase II cardiac rehab
- keep HR below levels that:
- elicit symptoms/signs limited
- cause dyspnea
- elicit a plateauing or decreasing SBP
- 240 or 110
- elicit ECG abnormalities
- elicit arrhythmias of >6 min
- use RPE
Abnormal responses to exercise in Phase II Cardiac Rehab
- SBP > 240, DBP> 110
- Systolic hypotension >20 bpm drop
- unusual HR response
- symptom provocation
- anginal response
- undue dyspnea
- excessive fatigue
- mental confusion/dizziness
- severe leg claudication
- signs
- pallor
- cold sweat
- ataxia
- pulmonary rales
- ECG abnormalities
can you preform resistance training in phase II cardiac rehab?
YES but with reservations
- onset:
- 5 weeks post MI
- 8 weeks post CABG
- 2 weeks post PTCA and stent
- 30-50% of 1 rep max
- 8-10 reps, 2-3x/wk with a day of rest in between
- large muscle groups
- control weights
- breathe/exhale during effort
Mode, Intensity, Duration, and Frequency of resistance training in Phase II cardiac rehab
- Mode → hand weights and/or machines
- Intensity
- RPE → 11-13
- no straining, no pain
- Duration
- 10-12 reps/set
- 1-2 sets
- Frequency
- 2-3x per week
Resistance considerations for Phase II Cardiac Rehab
- complete a smooth, controlled, and full ROM w/each activity
- balance your exercise between complementary muscle groups
- core strengthening
- avoid gripping the weight handles tightly
When is Phase III cardiac rehab occuring?
3-6 months post event
what is included in phase III cardiac rehab?
- HEP
- community exercise programs (like YMCA)
- pts may or may not be seen once/week
- no ECG monitoring
- self monitoring
goals of Phase III Cardiac Rehab
- achieve 50-80% of HRR on treadmill test (moderate activity)
- 3-4 sessions/week
- >45 min per session
what is included in Phase IV Cardiac Rehab?
- HEP
- self-monitoring
- environmental concerns
- adherence
considerations for exercising after a stent placement
- avoid vigorous exercise and heavy lifting for a short time after stent procedure
- an early symptom-limited exercise stress test (1 day post-op) did NOT increase the incidence of clinical stent thrombosis or access site complications
why do referrals to cardiac rehab remain low?
- lack of centralized method for referral
- inadequate communication among treatment teams, pts, and CR facilities
- unfamiliarity with CR among potential referring physicians
- limited access, competing responsibilities, and perceived inconvenience for the pt
