The Assessment Analysis of Feasibility for using Beta-Blockers in Coronary CT Angiography

Beta blockers are medications that reduce heart rate and make heartbeats more regular during CCTA exams, helping to reduce motion artifact and improve visibility of blood vessels for diagnosis. However, even when avoiding patients with contraindications, beta blockers continue to cause side effects, as well as fatigue and discomfort for both medical staff and patients due to the waiting time required for the medication to take effect, leading to delayed testing schedules. According to recent literature, advancements in hardware and software technology have diminished the importance of heart rate control for diagnostices. In other words, this implies the necessity for changes in the guidelines for beta-blocker administration. In our institution, the guidelines for beta-blocker administration were revised from prescribing them when the heart rate was over 70 beats per minute before 23 years ago to over 80 beats per minute since then. This study compares and analyzes CCTA examinationes before and after the revision of the guidelines, aiming to provide practical insights through case studies from our institution.
