Abstract
This study was done to evaluate the psychological state and anxiety of patients undergoing computed tomography coronary angiography (CTCA), and assess their acceptance and satisfaction compared to invasive conventional coronary angiography (CCA). A total of 442 consecutive patients (282 male; mean age 57.7±9.5years) who underwent CTCA for suspected or known coronary artery disease were evaluated with the Endler Multimodality Anxiety Scales (EMAS) before and after the scan, and a questionnaire administered after the scan. Among the 442 patients, 181 had a history of CCA. Two radiologists assessed the image quality of CTCA. Anxiety was more intense prior to the scan (EMAS score 51.7 vs. 46.7, p<0.01) and in patients with a history of CCA (EMAS score 55.5 vs. 49.1, p<0.01). Women presented more intense anxiety (EMAS score 59.5 vs. 47.3, p<0.01), higher mean heart rate (63.5±7.6 vs. 60.7±7.3beats per minute, p<0.01) and a lower image quality than men (p<0.0001). CTCA proved to be more acceptable than CCA because of accurate preparation, lower concern prior to the examination, negligible pain, higher comfort, and greater overall satisfaction (p<0.0001). Computed tomography coronary angiography is a patient-friendly imaging method because of the minimal perceived discomfort. Anxiety may affect CTCA image quality in women.
