Phase 1: inpatient lasts

2-4 days

• directly after event and in patients room

Phase 2 outpatient m duration

up to 36 sessions/ 12 weeks

• depending on AACVPR stratification

Phase 2 outpatient supervision and works on

• part supervised and part home base

• self monitoring strongly emphasized

Guideline for inpatient CR program should focus on:

• current clinical status assessment (s/s, EKG)

• mobilization

• identification and provision of info regarding modifiable risk factors/ self care

• discharge planning with a home PA and ADL and referral to outpatient

Patients in Phase 1 will work individually with an

exercise physiologist

The EP should be able to obtain

• HR

• BP

• Heart Sounds

• Lung sounds

What is the main focus in Phase 1 inpatient

flexibility and cardiorespiratory

Before beginning any type of PA what should be done

• base line assessment s

• risk stratified immediately to help guide initiation and progress of PA

AACVPR Parameters for Inpatient Cardiac Rehab Daily Ambulation

• no new or recurrent chest pain in previous 8 hours

• stable or falling creating kinase and troponin values

• no indication of decompensated Heart failure

• normal cardia rhythm and stable EKG for 8 hours

Phase 1 type/mode

walking, treadmill, cycle ergometer

Phase 1 time

-intermittent bouts of walking

• 3-5 min between

• rest can be a slower walk or rest

• attempt to have 2:1 exercise to rest ration

Phase 1 progression

progress to 10-15 min of continuous walking

Before leaving Phase 1 an individual should:

-strongly encouraged to participate in an outpatient program

• be counseled on how to identify abnormal s/s leading to medical evaulation

• be five a safe and progressive exercise prescription (until outpatient)

At phase 1 hospital discharge patient should have

-specific instruction regarding strenuous work

• these are permissible and should be avoiding

At the time of physical referral or program entry, the following assessment should be performed

• medical and surgical history

• physical exam

• review of cardiovascular tests and prodcedures

• current medication

• CVD risk factors

what should the medical and surgical history include

• most recent cardiovascular event

• cormobidities

• other pertinent medical history

What should the physical exam have an emphasis on

cardiopulmonary and musculoskeletal system

goals for outpatient cardiac rehab

• Develop and assist patient to implement a safe and effective formal exercise and lifestyle physical activity program

• Provide supervision and monitoring to detect change in clinical status

• Provide ongoing surveillance to patient's health care providers in order to enhance medical management

• Return patient to vocational and recreation activities or modify based on status

• Provide patient and partner/family education to optimize secondary prevention (risk factor modification) through aggressive lifestyle management and judicious use of cardioprotective medications

Components of outpatient cardiac rehab

• CV risk factor assessment and counseling on aggressive lifestyle management

• Education and support to make healthy lifestyle changes to reduce risk of secondary cardiac event

• Development and implementation of safe and effective personalized exercise plan

• Monitoring with goal of improving blood pressure, lipids/cholesterol, and diabetes mellitus

• Psychological/stress assessment and counseling

• Communication with each patient's physician and other health care providers regarding progress and relevant medical management issues

• Return to appropriate vocational and recreational activities

Phase 2 begins

1-2 weeks after patient is discharged

Duration of phase 2

2-12 weeks

What is the duration of phase 2 determined by

• risk stratification

• need for monitoring

• progression toward outcomes

What is happening during phase 2

• ECG monitoring

• self monitoring taught and enforced

• education with emphasis on risk factor reduction

How long does phase 3 last

often 3-4 weeks

Transition into phase 3 varies case by case from

often when vital signs remain relatively stable with increase workloads

Phase 3 entails

• more independent and group exercise

• patients are still supervised, but vitals are no longer strictly monitored

• further incorporate strength training and stretching

Before, during, and after exercise, the clinician should assess the following

• vitals (HR, BP, SPO2)

• body weight

• sign and symptoms or evidence of clinical status not necessarily related to exercise

• symptoms and evidence of exercise intolerance

• changes to medications

• ECG and HR monitoring via telemetry

What are s/s and or evidence in clinical status not necessarily related to exercise

• Dyspnea at rest

• light headedness

• irregular heart rate

• chest discomfort

ECK monitoring for patients with known stable CVD and low risk for complications

• may begins with continuous ECG monitoring

• decrease to intermittent or no ECG monitoring after 6-12 session or sooner is deemed appropriate

ECK monitoring for patients with know CVF and at moderate to high risk for cardiac complication

• begin with continuous ECG monitoring

• decrease to intermittent or no ECG monitoring after 12 sessions and as deemed appropriate

When considering removing or reducing ECG monitoring, the patient should understand

individual exercise level that is safe

Phase 2 Aerobic exercise frequency

at least 3 days a week preferably > or equal to 5 days/ week

Phase 2 Aerobic exercise intensity if GXT was performed

40-80% of HRR or VO2

• can be steady state or interval training

Phase 2 Aerobic exercise if no VO2 peak test was performed

+20-30 bpm of RHR for a standing or sitting exercise

• or RPE of 4-7

LOOK OVER INTERVAL TRAINING SLIDE

Phase 2 Aerobic exercise time

20-60 minutes

Phase 2 Aerobic exercise type

• arm ergometer

• treadmill

• elliptical

• stair climber

• cycle ergometer

Phase 2 Aerobic exercise progression if exercise test was performed

maintain (0%) to 20%

Phase 2 Aerobic exercise progression if no exercise test was performed

can increase up to 30 bpm above resting HR

Progression for cardiac individuals should

occur at a slower, more gradual progression

Criterial for participation (GETP)

• all risk classifications may participate in resistance training

• must occur with supervision

Contraindications for resistance training

• congestive heart failure

• uncontrolled dysrhythmias

• uncontrolled hypertension

• unstable symptoms

Criteria for cardiac rehab patient structured RT if they have undergone a percutaneous coronary intervention

• initiate RT prescription 2-3 weeks post intervention and

• 2 weeks of supervises aerobic training

started immediately if tolerated

Phase 2 resistance training progression

10-20%

• and the 2x2 rule

2 by 2 rule

when a patient is able to comfortably complete one to two reps over the desired of reps on two consecutive training sessions

If patients functional capacity has been measure by an exercise test and an ischemic threshold was identified as

angina and/ or > or equal 1 mm ischemic ST segment depression on exercise test

Exercise intensity must be keep

below ischemic threshold

Upper limit is

10 bpm below ischemic threshold

Classic angina pectoris that is induced with exercise training and relieved with rest or nitro is

sufficient evidence for the presence of myocardial ischemia

If peak Hr is unknown, what method is used

RPE method should be used to guide exercise intensity

<3 on modified Borg scale is

light, <40% of HRR

4-6 on modified Borg Scale is

somewhat hard, or 40-59% of HRR

7-8 on modified Borg Scale is

is hard or 60-80% of HRR

If their is updated medications

a new stress test may be needed

It is recommended that an exercise test be performed any time that symptoms or clinical changes occur

• change in their level of chest pain or dyspnea

• possibly for those with an ischemic etiology who have not undergone a coronary revascularization procedure

• those who have been incompletely revacularize

• those who have rhythm disturbances and desire to exercise to a higher intensity level

However, another exercise test may not be medically necessary in patients who

• have undergone complete coronary revascularization

• who are asymptomatic

• when it is logistically impractical

Systolic heart failure

thin, weak heart muscle
