Does the pre-scan Self-Rating Anxiety Scale score correlate with the success rate of computed tomography coronary angiography in adult patients?
Higher pre-procedural anxiety, as measured by the Self-Rating Anxiety Scale, is significantly associated with a lower success rate of obtaining diagnostically useful images during 64-slice CT coronary angiography.

Higher pre-scan anxiety may reduce CT coronary angiography success; leaves open whether mitigation strategies improve diagnostic yield.
OBJECTIVE: Computed tomography coronary angiography, a key method for obtaining coronary artery images, is widely used to screen for coronary artery diseases due to its noninvasive nature. In China, 64-slice computed tomography systems are now the most common models. As factors that directly affect computed tomography performance, heart rate and rhythm control are regulated by the autonomic nervous system and are highly related to the emotional state of the patient. The aim of this prospective study is to use a pre-computed tomography scan Self-Rating Anxiety Scale assessment to analyze the effects of tension and anxiety on computed tomography coronary angiography success. METHODS: Subjects aged 18-85 years who were planned to undergo computed tomography coronary angiography were enrolled; 1 to 2 h before the computed tomography scan, basic patient data (gender, age, heart rate at rest, and family history) and Self-Rating Anxiety Scale score were obtained. The same group of imaging department doctors, technicians, and nurses performed computed tomography coronary angiography for all the enrolled subjects and observed whether those subjects could finish the computed tomography coronary angiography scan and provide clear, diagnostically valuable images. Participants were divided into successful (obtained diagnostically useful coronary images) and unsuccessful groups. Basic data and Self-Rating Anxiety Scale scores were compared between the groups. RESULTS: The Self-Rating Anxiety Scale standard score of the successful group was lower than that of the unsuccessful group (P = 0.001). As the Self-Rating Anxiety Scale standard score rose, the success rate of computed tomography coronary angiography decreased. CONCLUSIONS: The Self-Rating Anxiety Scale score has a negative relationship with computed tomography coronary angiography success. ADVANCES IN KNOWLEDGE: Anxiety can be a disadvantage in computed tomography coronary angiography examination. The pre-computed tomography coronary angiography scan Self-Rating Anxiety Scale score may be a useful tool for assessing whether a computed tomography coronary angiography scan will be successful or not.

Li et al. (2015) conducted an observational in Planned for computed tomography coronary angiography. Self-Rating Anxiety Scale assessment was evaluated on Success of computed tomography coronary angiography (obtaining diagnostically useful coronary images) (p=0.001). Higher pre-scan Self-Rating Anxiety Scale scores were significantly associated with a lower success rate of 64-slice computed tomography coronary angiography (P=0.001).
