Key result
Only ~6% of CAD patients have good pre-procedure knowledge despite positive attitudes and practices.
Why the study?
Patients undergoing cardiac catheterisation and PCI often lack information and experience anxiety, compromising safety, self-care, and clinical outcomes.
Cross-Sectional (n=49)
No
Patients with coronary artery disease undergoing catheterization show significant knowledge deficits despite favorable attitudes and practices, highlighting the need for targeted educational interventions.

Low pre-procedure knowledge despite positive attitudes warrants caution assuming readiness; leaves open whether education improves outcomes.
Background Coronary artery disease remains the leading cause of global mortality. Patients undergoing cardiac catheterisation (CAT) and percutaneous coronary intervention (PCI) often experience anxiety and lack of information, which may compromise safety, self-care, and clinical outcomes. The Knowledge, Attitude and Practice (KAP) methodology allows for the identification of gaps and supports the design of targeted educational interventions. Purpose To evaluate the KAP of patients with coronary artery disease in a university hospital in Brazil. Methods A cross-sectional study was conducted between June 2023 and August 2024 with 49 patients from the haemodynamics sector of a university hospital in south-eastern Brazil. Sociodemographic and clinical data, as well as KAP information, were collected through a structured and previously validated questionnaire (Cronbach’s alpha >0.80). The KAP survey was divided into: (1) pre-procedure, addressing general knowledge and preparation; and (2) post-procedure, assessing self-care and recognition of warning signs after discharge. Analyses were performed using SPSS and STATA, including descriptive statistics, Fisher’s exact test, and multiple logistic regression (p<0.05). Results Of the 49 patients, 51% were female, 91.8% lived in urban areas, and 57.1% had education below high school level. The most prevalent comorbidities were hypertension (73.5%) and family history of heart disease (67.3%). In the pre-procedure evaluation, only 6.1% demonstrated good knowledge, whereas 69.4% showed positive attitudes and 85.7% good practices. In the post-procedure assessment, 28.6% presented good knowledge, 89.8% positive attitudes, and 93.4% good practices. Factors associated with higher odds of improved KAP included the desire to receive information through educational materials, having a mobile phone, and completing high school education (p<0.05). Conclusion Although most patients displayed favourable attitudes and practices, knowledge deficits were evident, particularly in the pre-procedure phase. Educational strategies tailored to patients’ preferences and access to information may enhance knowledge and improve the quality of care for individuals with coronary artery disease.

Fioresi et al. (2026) conducted a cross-sectional in coronary artery disease (n=49). Knowledge, Attitude and Practice (KAP) evaluation was evaluated on Knowledge, Attitude and Practice (KAP) in pre- and post-procedure phases. Among patients with coronary artery disease, pre-procedure knowledge was good in only 6.1%, while post-procedure knowledge was good in 28.6%, despite high rates of positive attitudes and practices.
