Love Your Heart: A Cleveland Clinic Podcast

The Power of Cardiac Rehab

Cleveland Clinic Heart & Vascular Institute

Cardiac rehabilitation has been shown to reduce the risk of hospital readmission and improve quality of life, with benefits that persist even years after completing the program. Erik Van Iterson, PHD, MS, MA describes how cardiac rehab can help people reach their heart health goals.

Erik Van Iterson, PhD, MS, MA:

Good morning, everyone. Thank you very much for tuning into this podcast focused on this topic of cardiac rehab, why it is critical. My name is Dr. Van Iterson. I am the Director of Cardiac Rehab at the Cleveland Clinic in Cleveland, Ohio. Today, I'll begin with giving a general overview of the modern cardiac rehab program and its key components, who are the patients who are eligible for the service? I'll begin with perhaps what we might all think about when the term cardiac rehab first arises. Many of us may not realize that, yes, exercise training is involved in cardiac rehab, but this only represents the origin story of cardiac rehab back when it first started in 1970.

In the modern day version of cardiac rehab, yes, exercise training still exists as a fundamental component of the service, but that exercise training can only be optimized when we look at cardiac rehab from a multidisciplinary perspective. Cardiac rehab always includes discussions and education with patients about exercise training, but also importance of blood pressure management, lipid control, blood sugar control for diabetes prevention, tobacco cessation if there's a concern there, and psychosocial, and mental health awareness, and education and strategies to manage that. And finally, important education on topics relating to diet, nutrition and body weight management.

And so, cardiac rehab is indeed a multidisciplinary systematic approach to applying secondary prevention therapies of known benefit. Cardiac rehab is a class one recommendation, and that cardiac rehab is always individualized to the patient regardless of what we're coming in for. We strongly encourage individuals who are eligible for cardiac rehab to get started as soon as possible. And for some of these patients, it can be in as little as one week, but typically most can start within 21 days following their hospital discharge. And that we don't want to delay cardiac rehab initiation, because we also know that every day that goes by beyond an ideal window of starting this program, there unfortunately becomes a lesser likelihood that a patient will begin the process.

Getting started early is better, and that it is optimal for directing the best benefits from not just the sessions per week or 12 consecutive weeks, or 36 sessions of cardiac rehab, but the lifelong practice of cardiac rehab after you get done with hospital-based care. When patients come into cardiac rehab, we take all that information and create what we call an individualized treatment plan. That means patients have a clear set of interventions defined to address each of the risk factors relating to those four component cardiac rehab. We set very specific goals for patients to work towards throughout the program, but also set them up for success beyond cardiac rehab.

And that we want patients to not just, of course, participate, but we want them to be adherent to the education, the recommendations and ask questions. When patients initiate cardiac rehab, they participate in the sessions. They adhere to all the program recommendations, and then they complete cardiac rehab where a discharge consultation to discuss what they should do beyond cardiac rehab. 

Our largest patient population would be those coming the cardiac rehab with acute coronary syndrome, who have experienced myocardial infarction with or without revascularization. The data are very potent in showing the benefits of cardiac rehab at the short-term follow-up, medium-term follow-up, and long-term follow-up when viewing important key clinical outcomes.

And those important outcomes and the reduction in risk associated with cardiac rehab, of course, persists then in the long term, as long as individuals continue to adhere to and participate in those principles of secondary prevention. Some strong benefits gained through reductions in risk of hospitalization readmission, as well as improvements in quality of life. And importantly, these are outcomes that patients experience, not just in the short term or less than a year after finishing cardiac rehab, but these are benefits that patients tend to experience more than a year after the cardiac rehab experience began.

Even though changes in fitness or cardiac strength fitness aren't a prerequisite to extracting the benefits of cardiac rehab, we do know that in general there is a very strong association between fitness, and risk of cardiovascular disease, and other cardiovascular outcomes. Participating in cardiac rehab over the course of 36 sessions or 12 weeks, what the data shows is that regardless of what starting fitness level you have, everyone can benefit from cardiac rehab. And everyone can improve their fitness over the course of that program.

And the data showed that those coming in with the least fitness ended up demonstrating the largest improvements in their fitness by the time they finished rehab. But overall, that change in fitness across the entire patient cohort translated to reduction in all-cause mortality risk in the long term just from an increase in fitness.

Thank you very much. I appreciate your interest in this topic.
