The knowledge, attitude, and practice (KAP) toward post-percutaneous coronary intervention (PCI) self-management among Chinese patients remains unknown. This study investigated the KAP toward postoperative self-management among patients after PCI.

Patients exhibit poor knowledge, attitudes, and practices regarding post-PCI self-management, requiring enhanced education strategies.

This cross-sectional study recruited patients after PCI at Jishuitan Hospital, Beijing, between November 2022 and May 2023. Inclusion criteria comprised patients 1-3 months post-PCI, those capable of self-care, and those willingly participating. The questionnaire (49 items) was designed with reference to current guidelines (the Cronbach α = .829). The final questionnaire included four dimensions with 49 items. The Pearson correlation analysis and structural equation modeling (SEM) were used to determine the relationship among knowledge, attitude, and practice.

A total of 476 valid questionnaires were included. The knowledge, attitude, and practice scores were 8.24 ± 2.78 (possible range: 0-12), 21.61 ± 3.15 (possible range: 9-45), and 32.62 ± 3.75 (possible range: 10-50). The Pearson correlation analysis showed only knowledge scores were correlated with the attitude scores (r = .446, p < .001). The SEM showed that knowledge directly affects attitude (β = .616, p < .001) but had no influence on practice (β = .119, p = .155); attitude had no influence on practice (β = .015, p = .809).

This study indicated that patients had poor knowledge, unfavorable attitudes, and unsatisfied practice toward post-PCI self-management. Strengthening patient health education through diverse approaches is imperative.
