Unit
- Definition: Phase II Cardiac Rehabilitation is a structured outpatient program that begins after hospital discharge for a cardiac event. It typically lasts 12 to 36 sessions, with sessions occurring three times per week under continuous medical supervision. The program focuses on exercise training, education, and counseling to reduce cardiovascular risk.
- Timeline: Enrollment begins within 14 days of discharge for low-risk patients and up to 6 weeks for higher-risk patients. Early enrollment improves adherence and outcomes. Delays beyond 90 days are associated with increased readmission rates and reduced program benefits.
- Setting: Services are delivered in hospital-based outpatient departments, physician offices, or dedicated rehabilitation centers. The setting must be equipped with emergency equipment including defibrillators, oxygen, and a crash cart. Staff-to-patient ratios are typically 1:4 to 1:6 for exercise sessions.
- Regulatory Framework: In the US, Phase II is covered by Medicare under a specific benefit category. Services must be prescribed by a physician and provided by qualified personnel including nurses, exercise physiologists, and dietitians. Documentation requirements include initial assessment, progress notes, and discharge summary.
- Evidence Base: Meta-analyses show Phase II CR reduces cardiovascular mortality by 26% and hospital readmissions by 18%. Improvements in exercise capacity, quality of life, and risk factor control are well documented. Programs achieving 80% completion rates show the strongest outcomes.
- Patient Population: Eligible patients include those after myocardial infarction, coronary artery bypass grafting, percutaneous coronary intervention, heart valve surgery, or stable heart failure. Each patient receives an individualized plan based on clinical status and functional capacity.
- Core Team: The multidisciplinary team includes a medical director (cardiologist), program coordinator (registered nurse or exercise physiologist), dietitian, psychologist or social worker, and exercise specialists. Regular team meetings ensure coordinated care and goal tracking.
- Outcome Measures: Common tracked outcomes include peak VO2, 6-minute walk distance, resting heart rate and blood pressure, lipid profiles, body weight, depressive symptoms, and self-efficacy scores. Data collection occurs at baseline, midpoint, and program completion.
- Exercise Prescription: Each Phase II session incorporates aerobic, resistance, and flexibility exercises individualized to the patient's baseline functional capacity. Aerobic intensity is typically set at 40 to 70% of heart rate reserve or a rating of perceived exertion of 11 to 14 on the Borg scale. Progression in duration and resistance follows symptom-limited protocols to safely improve cardiorespiratory fitness and muscular strength.
- Educational Components: Patient education covers heart disease pathophysiology, medication adherence, dietary modifications such as the DASH diet, stress management techniques, and recognition of warning signs. Group sessions and individualized counseling reinforce self-management skills. Education is delivered by the multidisciplinary team throughout the program to empower patients in long-term risk reduction.
- Contraindications and Safety: Patients are continuously monitored via telemetry and blood pressure checks. Absolute contraindications to exercise include unstable angina, uncontrolled arrhythmias, symptomatic heart failure, or recent embolism. Relative contraindications require physician clearance before participation. Emergency protocols are reviewed regularly with staff to ensure rapid response to adverse events.
Scope of Practice
Role: Cardiac Rehabilitation Program Coordinator
Within scope:
- Conducting initial patient assessments including medical history and risk factor review
- Developing individualized care plans based on exercise tolerance and clinical guidelines
- Supervising exercise sessions and modifying prescriptions as needed
- Providing patient education on heart disease management and healthy behaviors
- Documenting progress and communicating with referring physicians
Outside scope:
- Diagnosing new cardiac conditions or interpreting imaging studies
- Prescribing medications or adjusting dosages without authorization
- Performing invasive procedures or administering intravenous therapies
- Making independent decisions beyond the care plan without physician input
- Billing for services without proper documentation and coding
Terminology
- Phase II Cardiac Rehabilitation
- Structured outpatient program for cardiac recovery, typically 12-36 sessions, including exercise, education, and counseling.
- Myocardial Infarction
- Heart attack caused by reduced blood flow to heart muscle, leading to tissue damage.
- Functional Capacity
- Maximum ability to perform aerobic exercise, often measured by metabolic equivalents (METs).
Quick Revision
- Phase II CR is a medically supervised outpatient program starting after hospital discharge.

- Program is covered by Medicare with specific documentation and staffing requirements.
- Evidence shows Phase II reduces cardiovascular mortality by 26% and readmissions by 18%.
- Coordinator scope includes assessment, plan development, supervision, and education.
