“The Spectrum of Change in the Elite Athlete’s Heart”
CME Information: 1 credit
Release date: August 2019 Valid through: August 2020
Introduction/Statement of Need:
Athlete’s heart (AH) is a term used to define cardiac remodeling due to high levels of physical activity. It is a functional, structural, and electrical adaptive change in response to high-intensity exercise for prolonged periods of time. This adaptation may include increases in the sizes of all four cardiac chambers, an increase in left ventricular (LV) wall thickness, and improvement in the diastolic filling of the left ventricle depending on the type of exercise performed. This remodeling allows increased stroke volume on demand and therefore increased cardiac output for any given heart rate. This in turn increases skeletal muscle oxygen delivery, enabling higher levels of performance and endurance.
This activity is designed for all cardiac sonographers and cardiovascular physicians with a primary interest and knowledge base in the field of echocardiography; in addition, residents, researchers, clinicians, intensivists, and other medical professionals.
At the end of this article the reader will better be able to:
1. Characterize the changes in cardiac anatomy and function with high intensity exercise
2. Describe cardiac remodeling over time in athletes
3. Understand the factors that contribute to cardiac remodeling with chronic exercise
