Assessment of Knowledge Regarding Coronary Artery Atherosclerosis and the Role of Interventional Radiology in Diagnosis and Treatment

Abstract

Introduction: Coronary artery disease (CAD) remains a leading cause of death and disability globally and within
Saudi Arabia, largely due to atherosclerosis, a progressive condition that narrows the coronary arteries and reduces
blood flow. Despite its growing prevalence, public awareness in Saudi Arabia remains low, particularly concerning
the role of interventional radiology in early diagnosis and minimally invasive treatment. Objectives: This study
evaluates the knowledge levels among patients in Saudi Arabia regarding coronary artery atherosclerosis and
the role of interventional radiology in diagnosis and treatment. Methodology: A cross-sectional study was
conducted between July 2025 and December 2025 using a structured online questionnaire. The target population
included Saudi citizens aged 18 years and above, excluding healthcare professionals, students, and individuals
living outside Saudi Arabia. Participants were recruited through social media platforms. A minimum sample
size of 384 participants was calculated using the infinite population formula at a 95% confidence interval and
5% margin of error. The survey consisted of three sections: informed consent, demographic data, and questions
assessing awareness, knowledge, and perceptions of CAD and interventional radiology
