Effect of KAP-Based Nursing Intervention on Patients Undergoing Coronary Artery Computed Tomography Angiography Review after Percutaneous Coronary Intervention

Objective: This study aimed to analyze the impact of nursing intervention based on knowledge, belief, and action theory (KAP) on patients undergoing coronary computed tomography angiography (CTA) review after percutaneous coronary intervention (PCI). Methods: The research subjects were post-PCI patients who underwent coronary CTA review in our hospital from July 2021, to July 2023. A total of 123 review patients were divided into two groups in accordance with whether they had experienced KAP-based care. The observation and control groups consisted of 65 and 58 cases, respectively (n = 58). The self-rating anxiety scale (SAS), heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP), CTA image quality, examination cooperation, and nursing satisfaction were compared between the two groups. Results: Compared with those of before nursing, the SAS scores of both groups after nursing were significantly reduced (p < 0.05). Compared with the control group, the observation group had significantly reduced SAS scores (p < 0.05). Compared with those before nursing, the HR, SBP, and DBP of both groups after nursing were significantly reduced (p < 0.05). Compared with the control group, the observation group showed significantly reduced HR, SBP, and DBP (p < 0.05). The grade I rate of the observation group significantly increased, the grade III rate was significantly reduced, and the image quality significantly improved compared with those of the control group (p < 0.05). No statistically significant difference was observed in the incidence of grade II between the two groups (p > 0.05). The total cooperation degree of the observation group was 93.86% (61/65), which was significantly increased compared with the total cooperation degree of 81.03% (47/58) in the control group (p < 0.05). The total satisfaction of patients in the observation group was 96.92% (63/65), which was significantly increased compared with the total satisfaction of 74.14% (43/58) in the control group (p < 0.001). Conclusion: Nursing based on the KAP model during coronary CTA review after PCI can significantly alleviate patients' negative emotions and improve CTA image quality. It can also improve patients' examination cooperation and nursing satisfaction.
