This randomized controlled trial aims to evaluate the effect of a mindfulness-based nursing intervention on anxiety levels and vital signs in patients undergoing open-heart surgery during the preoperative and early postoperative periods.

Patients undergoing open-heart surgery may experience high levels of anxiety due to the complexity of the surgical procedure, the intensive care environment, pain, invasive interventions, and the perception of a life-threatening condition. Increased perioperative anxiety has been reported to negatively affect vital signs such as blood pressure, heart rate, and respiratory rate, prolong recovery, and reduce patient comfort. Although pharmacological methods are commonly used to manage anxiety, they may cause adverse effects including sedation, respiratory depression, and hemodynamic instability. Therefore, non-pharmacological nursing interventions are of particular importance in cardiac surgery patients. Psychosocial and supportive nursing interventions have been shown to reduce anxiety and support physiological stability. In recent years, mindfulness-based interventions have emerged as safe and feasible approaches to reduce stress and anxiety through breath awareness, relaxation, and present-moment techniques. Previous studies in various surgical populations have demonstrated that mindfulness-based interventions can reduce anxiety levels and positively influence certain physiological parameters. However, randomized controlled trials evaluating structured and short-term mindfulness-based nursing interventions during the preoperative and early postoperative periods in open-heart surgery patients are limited. This study is designed as a quantitative, randomized controlled trial to evaluate the effects of mindfulness-based nursing interventions applied during the preoperative and early postoperative periods on anxiety levels and vital signs in patients undergoing open-heart surgery. The findings are expected to contribute to evidence-based nursing practices and support clinical care processes in the management of anxiety in cardiac surgery patients. The mindfulness-based nursing intervention consists of brief, structured sessions focusing on breath awareness, relaxation, and present-moment attention, delivered individually by a trained nurse during the preoperative and early postoperative periods. Outcome assessments, including anxiety questionnaires and vital sign measurements, will be performed by nurses who are not involved in the intervention and are blinded to group allocation.
