Objective: To study the effects of PDCA cycle nursing on athletic patients with coronary artery CT angiography. Methods: The medical records of 68 athletic patients (coronary artery CT angiography, 2020.4-2022.4) were selected and analyzed retrospectively. The athletic patients were divided into groups according to the nursing plan. The subjects in the control group were treated with routine nursing plan, while the athletic patients in the observation group were treated with PDCA cycle nursing plan. The image quality, success rate of one examination and nursing satisfaction were compared between the two groups, and the changes of vital signs and the change of anxiety of the two groups during the examination were compared. Results: All indexes of image quality in the observation group were better than those in the control group, and the success rate of one examination and nursing satisfaction were higher than those in the control group (P<0.05); the measured values of heart rate, diastolic blood pressure and systolic blood pressure in the observation group were lower than those in the control group, and the scores of the self-rating anxiety scale (SAS) at each time point after the examination were lower than those in the control group (P<0.05). Conclusion: The PDCA cycle nursing mode applied in the nursing of athletic patients with coronary artery CT angiography can ensure the image quality, improve the success rate of one examination, and help to stabilize the emotional state and vital signs of athletic patients, improve anxiety, and has the value of further promotion and application.
