Abstract Background Coronary artery disease (CAD) patients who have undergone coronary artery bypass grafting (CABG) often experience a severe psychological burden for a long period of time, which can adversely affect their post-operative prognosis. Therefore, this study aimed to evaluate the effect of a web-based Information-Knowledge-Attitude-Practice (WIKAP) continuous intervention on the psychological status, medical compliance, and quality of life (QoL) in patients with CAD after CABG surgery. Methods A parallel randomized clinical trial enrolled 174 CAD patients who underwent CABG at our hospital between January 2018 and December 2019. The participants were randomly divided into the Control and WIKAP group and received intervention for 12 months. The scores for anxiety, depression, medical compliance, and QoL were assessed on the first day (M0), 3rd month (M3), 6th month (M6), 9th month (M9) and 12th month (M12) after discharge. Furthermore, the occurrence of major adverse cardiac and cerebrovascular events (MACCE) was analyzed using the Kaplan-Meier curve and Cox proportional regression models for an additional 24-month follow-up period without any intervention. Results After the 12-month intervention, the scores of anxiety and depression were significantly reduced in the WIKAP group at M9 and M12 compared to those in the Control group (all P 0.05). Cox proportional regression analysis also showed that the nursing intervention (Control vs. WKIAP) was not associated with the incidence of MACCE. Conclusion WIKAP nursing intervention effectively improved the psychological health, medical compliance, and QoL in CAD patients who underwent CABG operation, but it did not prolong MACCE-free survival. Trail registration The study is registered in isrctn.org: ISRCTN13653455.
