# Cardiovascular physical therapy: cardiac rehabilitation

Receiving a diagnosis of heart disease or experiencing a cardiovascular event such as a heart attack can cause a lot of anxiety, especially when it comes to returning to an active, normal life. You may wonder what activities you will be able to resume, how you can regain your physical capacity, and how you can reduce the risk of it happening again.

Here's the good news: cardiovascular physiotherapy, offered as part of hospital-based cardiac rehabilitation programs, can help you regain control of your health. This specialty combines supervised exercise, therapeutic education, and lifestyle changes to optimize your recovery and improve your long-term quality of life.

Service not offered at Physioactif. Cardiovascular physiotherapy requires a specialized clinical environment with continuous cardiac monitoring. We invite you to consult the cardiac rehabilitation programs available at hospitals in the Montreal area, including the Montreal Heart Institute, the CHUM, and the MUHC.

This article introduces you to the fundamentals of this specialty, its organization into rehabilitation phases, the conditions treated, and the benefits demonstrated by research. To learn more about the different specialties in physical therapy, check out our comprehensive guide to types of physical therapy.

What is cardiovascular physical therapy?

Cardiovascular physical ^therapy is a multidisciplinary approach to care focused on the rehabilitation of people with cardiovascular disease. It aims to optimize physical capacity, reduce symptoms, improve quality of life, and decrease the risk of recurrence or complications.

This specialty is based on three fundamental pillars:

Supervised therapeutic exercise: Individualized training programs tailored to each person's cardiac condition, carried out under medical supervision with continuous cardiac monitoring. Therapeutic education: Information about heart disease, recognizing warning signs, managing stress, modifying risk factors, and adhering to medical treatment. Psychosocial support: Support to manage anxiety and depression frequently associated with heart disease, and facilitate a return to daily and professional activities. This educational component is also central to the women's health physical therapy, where understanding one's condition helps to manage it better.

Cardiac rehabilitation physical ^therapists work closely with cardiologists, specialized nurses, nutritionists, and psychologists to provide comprehensive and coordinated care. This multidisciplinary approach is similar to that used in geriatric physical therapy, where collaboration between professionals is essential for treating complex patients.

What are the four phases of cardiac rehabilitation?

Cardiac rehabilitation is structured in four distinct phases that accompany the individual from hospitalization to long-term maintenance of their achievements[⁴].

Phase	Location	Duration	Primary objective
Phase I	Hospital (acute care)	3-7 days	Early mobilization, prevention of complications
Phase II	Rehabilitation center	8–12 weeks	Intensive supervised exercise, education
Phase III	Mixed (supervised + home)	6-12 months	Transition to independence
Phase IV	Home/community	For life	Long-term retention of acquired knowledge

Phase I: Acute inpatient rehabilitation

^This phase begins upon admission to the hospital, usually within 24 to 48 hours following an acute cardiac event such as a myocardial infarction or cardiac surgery.

The main objectives include preventing complications associated with prolonged bed rest, initially assessing exercise tolerance, and initiating gradual mobilization. Activities include breathing exercises, gentle joint movements, and a gradual progression to standing and assisted walking.

^The average length of hospital stay varies from 3 to 7 days depending on the condition and the procedure performed. The team also assesses the person's ability to perform basic activities such as washing, dressing, and moving around safely before returning home.

Phase II: Supervised outpatient rehabilitation

^Phase II is considered the core of cardiac rehabilitation. It usually begins 2 to 6 weeks after discharge from the hospital and takes place in a specialized rehabilitation center.

This phase includes:

Comprehensive initial assessment: Stress test with cardiac monitoring (stress test on a treadmill or exercise bike), assessment of functional capacity, identification of modifiable risk factors, and setting of personalized goals. Supervised exercise program: 60- to 90-minute training sessions, 2 to 3 times a week for 8 to 12 weeks[⁸]. Each session includes a warm-up, cardiovascular training, muscle strengthening, and a cool-down. The intensity of the exercise is adjusted according to the target heart rate calculated from the initial stress test. Therapeutic education sessions: Understanding heart disease, managing medication, changing eating habits, quitting smoking, managing stress, and recognizing warning signs that require urgent medical attention.

Research shows that participation in a Phase II program reduces cardiovascular mortality by 26% and the risk of rehospitalization by 18^%.

Phase III: Transitional Rehabilitation

This intermediate phase prepares the transition to complete independence. It generally lasts 6 to 12 months and combines supervised sessions at intervals with independent exercise at home[¹⁰].

The objectives include maintaining the gains made in phase II, gradually increasing autonomy in exercise management, and consolidating lifestyle changes. Clinical monitoring is less frequent but still takes place in order to adjust the program according to changes in the patient's condition.

Phase IV: Long-term maintenance

Phase IV represents a lifelong commitment to an active and healthy lifestyle. The individual exercises independently, often at a community center or at home, with periodic follow-ups with the rehabilitation team[¹¹].

This phase is crucial to prevent the loss of benefits gained during the previous phases. Studies show that approximately 50% of gains in functional capacity can be lost within a year of stopping a structured program if the person does not maintain a regular level of physical activity[¹²].

Which cardiovascular conditions can benefit from rehabilitation?

Cardiovascular physical therapy addresses a wide range of cardiac and vascular conditions.

Acute coronary syndrome and myocardial infarction

^After a myocardial infarction (heart attack), cardiac rehabilitation is considered an essential component of treatment. It helps restore functional capacity, reduce anxiety associated with physical activity, and promote a return to an active lifestyle.

People who have completed a rehabilitation program after a heart attack have a 20 to 30% reduction in the risk of death and a significant improvement in their quality of life[¹⁴].

Heart failure

Heart ^failure, a condition in which the heart does not pump blood efficiently, benefits greatly from appropriate cardiac rehabilitation. Contrary to past recommendations that advocated rest, modern research shows that supervised exercise improves functional capacity, reduces symptoms, and lowers the risk of hospitalization.

An appropriate exercise program can increase exercise capacity by 15 to 30% in people living with heart failure[¹⁶].

Heart surgery

People who have undergone coronary artery bypass grafting, valve replacement, or other major heart surgery are candidates for rehabilitation[¹⁷]. The program aids in postoperative recovery, chest (sternum) pain management, strengthening respiratory capacity, and gradually resuming activities.

Rehabilitation after cardiac surgery accelerates functional recovery and reduces postoperative complications such as pneumonia and atelectasis[¹⁸].

Peripheral artery disease

Peripheral artery ^disease(PAD) affects the arteries in the legs and causes intermittent claudication, which is muscle pain triggered by walking and relieved by rest. Supervised walking training is the first-line treatment for improving pain-free walking distance.

Supervised exercise programs can increase maximum walking distance by 50 to 200% after 3 to 6 months of training[²⁰].

Other indications

Cardiac rehabilitation is also beneficial for people with stable angina, cardiac arrhythmias, heart transplants, pacemaker or defibrillator implants, and valvular heart disease[²¹].

How is exercise prescribed for cardiac patients?

The prescription of exercise in cardiac rehabilitation follows rigorous principles based on each person's initial assessment and risk profile.

Assessment of functional capacity

Cardiorespiratory exercise ^testing with continuous ECG monitoring is the standard tool for assessing functional capacity and determining safe exercise parameters. This test measures maximal oxygen consumption (VO₂ max), maximal heart rate, blood pressure response to exercise, and the onset of symptoms or ECG abnormalities.

^This data can be used to calculate the optimal training zone, which is generally between 40% and 80% of maximum capacity, depending on fitness level and risk profile.

Training methods

Cardiovascular training: Treadmill walking, stationary cycling, arm ergometer, or elliptical trainer are the most commonly used methods. Progress is made gradually by increasing the duration (from 15 to 45 minutes per session) and then the intensity. Resistance training: Strength training is included in the program because muscle weakness is common in people with heart disease and limits functional capacity.²⁴]. Light to moderate weights (30 to 60% of maximum strength) are used with a high number of repetitions (10 to 15). These principles of gradual progression are similar to those used in physical therapy for chronic pain, where the exercise must be adapted individually. Interval training: This approach alternates periods of more intense effort with periods of active recovery. Recent studies suggest that interval training can produce greater gains in functional capacity compared to moderate continuous training, particularly in people with heart failure.²⁵].

Monitoring and stopping criteria

^During exercise, monitoring includes continuous ECG monitoring, regular blood pressure measurement, heart rate assessment, and observation of symptoms (chest pain, excessive shortness of breath, dizziness).

Criteria for immediate cessation of exercise are established to ensure safety: significant chest pain, significant arrhythmias, excessive drop or rise in blood pressure, severe shortness of breath, or signs of poor perfusion such as paleness or confusion.

When should you seek cardiovascular physical therapy?

Cardiac rehabilitation is recommended in several specific clinical situations.

After an acute cardiac event

Referral to a rehabilitation program should be automatic after myocardial infarction, acute coronary syndrome, percutaneous coronary intervention (angioplasty with stent placement), or revascularization surgery[²⁷].

International guidelines consider rehabilitation to be an integral part of the continuum of care, on a par with medication and cardiac interventions[²⁸].

Diagnosis of chronic heart disease

People diagnosed with heart failure, stable angina, or peripheral artery disease benefit from early referral to rehabilitation, even in the absence of a recent acute event[²⁹].

Limiting signs and symptoms

Reduced exercise capacity (abnormal shortness of breath during light activities, excessive fatigue, difficulty performing daily tasks) warrants evaluation and possibly referral to rehabilitation after reversible causes have been ruled out.

Access to programs in Montreal

Several hospitals in the Montreal area offer structured cardiac rehabilitation programs:

Hospital	Program	Type of services
Montreal Heart Institute (MHI)	Internationally recognized program	Complete rehabilitation with medical follow-up, supervised exercise, education
CHUM	Cardiovascular rehabilitation	Program integrated with cardiology services
MUHC (Royal Victoria, General)	Multi-site programs	Comprehensive multidisciplinary approach
Sacred Heart Hospital of Montreal	Cardiac rehabilitation	Services with a multidisciplinary team

Referrals to these programs are usually made by the treating cardiologist, but some centers accept referrals from family doctors.

Frequently Asked Questions

Is cardiac rehabilitation safe?

^Yes. Although exercise always carries a theoretical risk for people with heart conditions, supervised rehabilitation programs are extremely safe. Data shows a rate of serious cardiac events of only 1 per 60,000 hours of supervised exercise. Continuous monitoring and emergency protocols in place minimize the risk.

How long does a rehabilitation program last?

Phase II (intensive supervised rehabilitation) typically lasts 8 to 12 weeks with 2 to 3 sessions per week, for a total of approximately 24 to 36 sessions[³¹]. The total duration, including the transition and maintenance phases, extends over several months to years.

Is it covered by insurance?

In Quebec, cardiac rehabilitation programs offered in hospitals are covered by the Régie de l'assurance maladie du Québec (RAMQ) and do not require any direct payment from the patient. However, certain complementary services or programs in the private sector may incur variable costs.

Can I do rehabilitation at home?

Remotely supervised home rehabilitation programs exist and may be an option for some people who are unable to travel to^a rehabilitation center. However, supervised rehabilitation remains the preferred approach, particularly in the first few weeks following a cardiac event, as it offers optimal monitoring and comprehensive multidisciplinary support.

What are the proven benefits of cardiac rehabilitation?

Studies show multiple benefits: a 26% reduction in cardiovascular mortality, an 18% decrease in rehospitalizations, a 15-30% improvement in functional capacity, a reduction in angina and shortness of breath symptoms, an improvement in quality of life, and a decrease in anxiety and depression[³³].

Should I continue the exercise after the program?

Absolutely. The benefits of cardiac rehabilitation are only maintained if the person continues to lead a physically active lifestyle after the structured program has ended[³⁴]. The long-term maintenance phase IV is essential for preserving the gains made and preventing the progression of heart disease.

What exercises are safe for someone with heart disease?

Specific ^exercises depend on individual condition and are determined after a comprehensive assessment including a stress test. In general, walking, stationary cycling, arm ergometer, and strengthening exercises with light weights are commonly used. Intensity, duration, and progression are individualized according to functional capacity and therapeutic goals.

Conclusion

Cardiovascular physical therapy is an essential component of the treatment of heart and vascular diseases. Through structured four-phase programs, it combines supervised therapeutic exercise, education, and psychosocial support to optimize recovery and reduce the risk of future complications.

The benefits of cardiac rehabilitation are well established by research: significant reduction in mortality, improvement in functional capacity and quality of life. Despite its proven effectiveness, rehabilitation remains underutilized, with only 20 to 30% of eligible individuals participating.

If you or a loved one is living with heart disease, don't hesitate to talk to your cardiologist about participating in a cardiac rehabilitation program. Montreal hospitals offer comprehensive, accessible programs that can transform your recovery and long-term quality of life.
