Cardiac rehabilitation is a core comprehensive intervention system for the full-cycle management and secondary prevention of cardiovascular diseases. Evidence-based medicine has demonstrated that this system can effectively improve patients' cardiopulmonary function, exercise endurance, and quality of life, reduce readmission rates and the risk of cardiovascular adverse events. Currently, it has been listed as a Class I recommended plan by multiple authoritative guidelines at home and abroad. At present, there are a large number of cardiovascular disease patients in China. Although the cardiac rehabilitation industry is steadily developing, there are still problems such as low patient participation rate, insufficient standardization, single evaluation system, homogeneous intervention plans, and weak management of special populations. This article combines five studies in this column to explore prognostic markers, construct non-exercise cardiopulmonary function prediction models, analyze traditional exercise rehabilitation mechanisms, and review cutting-edge achievements in the field of perioperative rehabilitation in cardiac surgery. It objectively evaluates the clinical value, application advantages, and limitations of various technologies and plans, and looks forward to future development directions, aiming to provide evidence-based reference and theoretical support for clinical practice, scientific research innovation, and disciplinary construction of cardiac rehabilitation in China.
