Mitochondrial Bioenergetics and Cardiac Rehabilitation: Bridging Basic Science and Clinical Practice

Area of Science:

• Cardiology and Exercise Physiology
• Mitochondrial Biology

Background:

• Cardiovascular diseases (CVDs) are a major global health concern, necessitating effective secondary prevention.
• Comprehensive cardiac rehabilitation (CR) is a proven, cost-effective intervention for managing CVDs.
• Mitochondrial bioenergetics, including biogenesis, dynamics, and mitophagy, are increasingly recognized as key mechanisms in CR's benefits.

Purpose of the Study:

• To synthesize molecular insights on mitochondrial function with clinical CR guidelines.
• To evaluate four national CR guidelines (Poland, France, US, Portugal) and the European Society of Cardiology (ESC) recommendations.
• To analyze exercise modalities and prescription parameters within these guidelines.

Main Methods:

• Systematic review and synthesis of molecular evidence and clinical guidelines.
• Focused analysis on exercise components: aerobic, resistance, and high-intensity interval training.
• Inclusion criteria ensured guidelines provided complete and detailed data on CR components.

Main Results:

• The review identified key exercise modalities and prescription parameters within selected CR guidelines.
• Analysis highlighted variations and commonalities in exercise recommendations across different national and European guidelines.
• The role of mitochondrial mechanisms in CR benefits was considered in relation to guideline components.

Conclusions:

• Understanding the interplay between mitochondrial bioenergetics and exercise is crucial for optimizing CR.
• Comparative analysis of guidelines can inform best practices for CR program design.
• Further research may refine exercise prescriptions to maximize mitochondrial adaptations for CVD secondary prevention.
