Key Result
The 2021 ESC and 2019 ACC/AHA guidelines both emphasize lifestyle optimization and risk factor management for cardiovascular disease prevention, despite differences in risk assessment tools.
Key Points
- This review aims to compare the primary prevention recommendations for cardiovascular disease from American and European guidelines.
- Reviewed the 2021 European Society of Cardiology and 2019 American College of Cardiology/American Heart Association guidelines.
- Examined differences in risk assessment tools and philosophical approaches to prevention.
- Analyzed conventional and nonclassical risk factors acknowledged by both guidelines.
- Both guidelines stress lifestyle optimization but differ in risk factor management strategies.
- The ESC guideline includes nonclassical risk factors like environmental issues more prominently.
- Variations in risk assessment tools reflect differences in the populations they target.

Abstract
This review compares the primary prevention recommendations of the recent 2021 European Society of Cardiology (ESC) and 2019 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines on cardiovascular disease (CVD) prevention. Although the 2019 ACC/AHA guideline represents its inaugural version, the ESC guideline is an update to its 2016 statement. Both guidelines address prevention using a holistic approach and agree on the importance of lifestyle optimization and intensified risk factor management. Cardiovascular (CV) risk assessment tools differ, reflecting the unique populations being screened as well as philosophical differences to their approach. Conventional risk factors are used to estimate CV risk, but each guideline acknowledges the role of risk modifiers to refine risk calculation. The ESC guideline recognizes the importance of nonclassical risk factors, including environmental issues, that impact CV health at the population level and calls for legislative action at the local, regional, and national levels.
