The maintenance of low heart rates is preferable when conducting coronary CT angiography (CCTA). Current medical publications recommend a heart rate less than 60 beats/min for optimal image and radiation dose reduction. Patients undergoing CCTA are usually given beta-blockers if there are no contraindications one hour before the test to control the heart rate. Another method that is used in moderating the heart rate of patients undergoing CCTA is ivabradine. Ivabradine is a novel heart rate-reducing agent that has the potential to be an attractive alternative to currently available drugs to achieve optimal heart rate control in patients undergoing CCTA (Adile et al., 2012). It is a specific heart rate-lowering drug that acts by selectively inhibiting the pacemaker current in the sinoatrial node. Unlike beta-blockers, ivabradine does not affect myocardial contractility, does not cause changes in blood pressure, and has no effect on respiratory function. This study aims to focus on the differences between ivabradine and beta blockers in their respective effects for controlling the heart rate of patients undergoing CCTA. Clinical Practice Question In patient undergoing CCTA how does Ivabradine compared to Beta blockers for heart rate control? Critical Appraisal Components 1st Critical Appraisal Component in CETEP Model Evidence-Based Factors: Research The clinical practice question of this posed here includes will be used to examine the effects of ivabradine to the heart
