Intravenous Landiolol for Rate Control in Supraventricular Tachyarrhythmias in Patients with Left Ventricular Dysfunction: A Systematic Review and Meta-Analysis

Abstract

Background: This systematic review explores the effects of landiolol administration in individuals presenting with supraventricular tachyarrhythmia (SVT) and concurrent left ventricular dysfunction, without being septic or in a peri-operative period. Methods: We systematically searched PubMed, Cochrane, Web of Science, and Scopus databases, retrieving a total of 15 eligible studies according to prespecified eligibility criteria. Results: Patients treated with landiolol experienced a substantial reduction in heart rate (HR) (mean HR reduction: 42 bpm, 95% confidence intervals (CIs): 37–47, I2 = 82%) and were more likely to achieve the target HR compared to those receiving alternative antiarrhythmic therapy (pooled odds ratio (OR): 5.37, 95% CIs: 2.87–10.05, I2 = 0%). Adverse events, primarily hypotension, occurred in 14.7% of patients receiving landiolol, but no significant difference was observed between the landiolol and alternative antiarrhythmic receiving groups (pooled OR: 1.02, 95% CI: 0.57–1.83, I2 = 0%). No significant difference was observed between the two groups concerning sinus rhythm restoration (pooled OR: 0.97, 95% CI: 0.25–3.78, I2 = 0%) and drug discontinuation due to adverse events (pooled OR: 5.09, 95% CI: 0.6–43.38, I2 = 0%). Conclusion: While further research is warranted, this systematic review highlights the potential benefits of landiolol administration in the management of SVTs in the context of left ventricular dysfunction.

The Impact of Chronic Oral Beta-Blocker Intake on Intravenous Bolus Landiolol Response in Hospitalized Intensive Care Patients with Sudden-Onset Supraventricular Tachycardia—A Post Hoc Analysis of a Cross-Sectional Trial

“…However, in one-third of patients, there was no effect. Landiolol has already shown a high potential for rhythm- and frequency-controlling effects in several studies in the ICU setting [ 7 , 8 , 21 , 22 , 26 , 27 , 28 , 29 ]. Compared with the frequently used amiodarone in intensive care medicine, Landiolol also showed a significantly faster rhythm-controlling effect in postoperative atrial fibrillation but with similar effectiveness in terms of rhythm control rates [ 30 ].…”
