Coronary Angiography and Percutaneous Coronary Interventions (PCI) are diagnostic and therapeutic procedures often for patients with CAD. Although these are minimally invasive and have relatively low risk, most patients showed pre-procedural anxiety. The present study assessed the anxiety level and factors associated with it among older Adults undergoing coronary angiography and percutaneous coronary intervention. A total of 155 older patients undergoing Coronary Angiography and PCI at Cardiac Catheterization Units, Zagazig University Hospitals were selected. The results showed that 58.1% of the studied older adults patients had moderate anxiety, while, 25.8% of them had severe anxiety and only 16.1% of them had mild anxiety level. The highest rates of anxiety were found in in female patients with age greater than or equivalent to 70 years compared with other age groups, with low educational level, had chest pain attack and those without previously cardiac intervention.
