The Efficacy and Safety of Ivabradine in Arrhythmias: A Systematic Review

ABSTRACT

Background: Treating arrhythmia adequately is crucial to prevent cardiac morbidity and mortality. Previous studies report that ivabradine may increase the risk of atrial fibrillation; however, emerging evidence shows that the drug may have beneficial effect in treatment of arrhythmia. Purpose: The present research explored the clinical evidence regarding the clinical efficacy and safety of ivabradine to treat arrhythmias. Method: A comprehensive literature search was conducted using MEDLINE, EMBASE, Scopus, Google Scholar and Web of Science databases. Full text articles that report on the use of ivabradine in human subjects with arrhythmia are included. Studies not written in English language and those not published in the period between 2016 and May 2021 were excluded. Results and discussion: Eight articles were included in the current review after screening a total of 1100 articles. The studies depicted that ivabradine is effective in improving ventricular rate, heart rate, and sinus rhythm in atrial fibrillation and has limited or no side effects. In addition, the findings indicate that combining ivabradine with other medications is more effective for improving the ventricular rate and maintain sinus rhythm than when used alone. Conclusion: Ivabradine alone or in combination with other medications can therefore be used as a potential treatment for arrhythmias. (AU)
