Effects of Mindfulness-based Interventions on Psychophysiological Recovery and Physical Functioning in Patients After Coronary Heart Surgery

Background: If patients with coronary heart disease are not properly controlled and treated, it is not only easy for the disease to relapse and cause angina pectoris, which will prevent the heart from receiving sufficient blood and oxygen supply, leading to an increase in the severity of the disease, and may lead to coronary artery bypass surgery, but postoperative complications may occur. Due to reduced respiratory muscle vitality, chest wound pain caused by median sternotomy surgery, and bed rest, resulting in incomplete lung expansion or lung collapse, discomfort due to physiological symptoms, and fear of life-threatening disease, and the risk of disease The uncertainty of treatment causes patients to have negative emotions of anxiety and depression, affecting their sleep quality. Purpose: The purpose of this study is to explore the effect of mindfulness on the physical and mental recovery and physical function of patients after coronary heart surgery. Methods: Convenience sampling was adopted, and patients in the cardiology ward of a northern medical center were selected as the research subjects. Eligible subjects were assigned to the experimental group (mindfulness treatment) and the routine care group. The subjects were tested on the day before surgery and on the seventh day after intervention. Physical and mental recovery (awareness of inner feelings, anxiety, depression, sleep quality, pain) and physical function (vital capacity, cardiorespiratory endurance, dyspnea after exercise) were measured, and the secondary measurement data were statistically analyzed using SPSS 29.0 for Windows software suite. Compare the differences between the two groups in physical and mental recovery and physical function.
