Objective: To explore the positive exercise experience of patients with coronary heart disease after PCI surgery. Methods: purposive sampling was used to conduct semi-structured interviews with 15 patients with coronary heart disease after PCI in a tertiary hospital in Baise City from March to May 2024. The data was analyzed using the Colaizzi seven step method. Results: Three themes were extracted as a result. Knowledge is the foundation of active movement, including the transmission of external advantageous resources and actively absorbing new information; Belief is the driving force behind sports, including stimulating enthusiasm for sports, promoting sports consciousness, and enhancing sports confidence; Behavior is the foundation of exercise, including personalized formulation of exercise prescriptions, improvement of exercise compliance, and positive incentives for exercise experience. Conclusion: Patients with coronary heart disease after PCI can form positive emotional experiences during exercise, internalize internal and external advantageous resources into exercise beliefs, and stimulate exercise behavior. Nurses should be guided by the knowledge, belief, and action model to improve patients' mastery of motor knowledge, perceive positive incentives for exercise, and form sustained exercise behavior.
