Discussion/General Information

Cardiac rehabilitation is a program of multidisciplinary interventions, designed to assist clinically suitable individuals to attain and maintain their optimal level of functioning. Over the past two decades, risk factor modification programs for individuals with cardiac conditions, commonly referred to as cardiac rehabilitation, have evolved into a comprehensive management strategy. The American Heart Association (AHA) and the American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR) define cardiac rehabilitation programs as, “Coordinated, multifaceted interventions designed to optimize a cardiac patient’s physical, psychological, and social functioning, in addition to stabilizing, slowing, or even reversing the progression of the underlying atherosclerotic processes, thereby reducing morbidity and mortality” (Leon, 2005). Interventions include, “Baseline patient assessments, nutritional counseling, aggressive risk factor management, (i.e., lipids, hypertension, weight, diabetes, and smoking), psychosocial and vocational counseling, and physical activity counseling and exercise training, in addition to the appropriate use of cardioprotective drugs” (Leon, 2005).

According to a 2007 scientific statement from the AHA and the AACVPR (Balady, 2007), which addresses the core components of cardiac rehabilitation/secondary prevention programs, the following is noted:

Symptom-limited exercise testing is strongly recommended prior to participation in an exercise-based CR program. The evaluation may be repeated as changes in clinical condition warrant. Test parameters should include assessment of heart rate and rhythm, signs, symptoms, ST-segment changes, hemodynamics, perceived exertion, and exercise capacity. On the basis of patient assessment and the exercise test if performed, it is recommended to risk stratify the patient to determine the level of supervision and monitoring required during exercise training.

Goel and colleagues (2011) conducted a retrospective review which looked at 2395 individuals over a 14 year period that underwent percutaneous coronary intervention. Of the 2395 individuals who underwent percutaneous coronary intervention, 964 of them enrolled in cardiac rehabilitation following the intervention. Mean follow-up was 6.3 years. During that time, there were 503 deaths, of which 199 were due to cardiovascular disease. Revascularization was required in 755 individuals and 394 individuals had subsequent myocardial infarction. The authors reported a 45% to 47% decrease in mortality of those individuals who participated in cardiac rehabilitation after percutaneous intervention compared with those individuals who did not participate in cardiac rehabilitation.

A study by Lee and colleagues (2014) reported on 576 individuals who were post drug-eluting stent implantation for coronary artery disease who were then referred for cardiac rehabilitation. A total of 288 participants successfully completed the cardiac rehabilitation program. The primary endpoint was in-stent luminal loss at a 9-month angiographic follow-up. Those who completed the cardiac rehabilitation program had a 35% less in-stent luminal loss when compared to those who didn’t complete the cardiac rehabilitation. Those in the cardiac rehabilitation group also showed an improvement in overall risk factors including current smoking, biochemical profiles, depression, obesity and exercise capacity.

Exercise training is the principal component of cardiac rehabilitation, since it results in increased peak exercise capacity, which is usually expressed in METs (metabolic equivalents). This is the total oxygen requirement of the body, with 1 MET equal to 3.5 mL of oxygen consumed per kilogram of body weight per minute. Exercise training improves MET capacity by 10% to 50%, resulting in improved oxygen delivery and extraction by exercising skeletal muscles, thereby decreasing the cardiovascular requirements of exercise and increasing the amount of work that can be done before ischemia occurs. Although dynamic aerobic exercise is necessary to improve cardiovascular endurance, resistance exercise is becoming a useful adjunctive component of the exercise regimen as well. Resistance training should be included in the exercise program to minimize loss of muscle mass.

Cardiac rehabilitation programs are generally divided into four phases: phase I, inpatient or recovery phase; phase II, outpatient or intermediate phase; phase III, community-based or home long-term phase; phase IV, maintenance (Thompson, 2007).

Phases of Cardiac Rehabilitation

Phase

Type of Program

Duration

Description

I

Inpatient

Days

  • Inpatient or recovery phase
  • Begins as soon as the individual is medically stable following a cardiac event (e.g., myocardial infarction, bypass surgery) and continues while the individual remains in the hospital
  • Consists of 1) early assumption of upright posture; 2) progressive exercise and self-care based on individual tolerance; 3) education; and 4) risk factor identification and initial attempts at modification.

II

Outpatient, immediately after hospitalization

2 – 12 weeks

  • Outpatient or intermediate phase
  • Initiated within a few weeks after hospital discharge
  • Consists of 1) supervised exercise training to maximize functional capacity, teach safe exercise practices, and identify individuals at risk for complications; 2) risk factor modification; and 3) education about medications, signs and symptoms of heart disease and its progression, dietary modifications and activity guidelines.

III

Late recovery period

Minimum of 6 months beyond phase II

  • Community-based or home long-term phase
  • Consists of a lifelong program committed to encourage exercise and a healthful lifestyle to minimize recurrence of cardiac problems.
  • Such programs are usually undertaken at home or in a fitness center.

IV

Maintenance

Indefinite

  • Consists of efforts to modify risk factors and a routine program of physical activity that individuals should continue indefinitely.
  • For some programs, phase IV rehabilitation is combined with phase III. All cardiac rehabilitation programs, however, recommend some form of indefinite maintenance for their participants.

 

Definitions

Duke Treadmill Score (DTS): A quantitative means of expressing cardiac risk derived entirely from the exercise ECG. It incorporates ST segment deviation (depression or elevation), treadmill time (METS) and exercise-induced angina. The angina index has a value of 0 if there is no angina during exercise, 1 if the individual had non-limiting angina and 2 if angina was the reason the individual stopped exercising. The typically observed range for the DTS is highest risk of –25 to lowest risk of +15.
