Safety and efficacy of omecamtiv mecarbil for heart failure: A systematic review and meta-analysis

To assess the safety and efficacy of omecamtiv mecarbil compared with placebo in heart failure (HF) patients. We searched PubMed, Web of Science, Cochrane Library, and SCOPUS until August 15th, 2021. We included all randomized controlled studies comparing omecamtiv mecarbil with placebo in heart failure patients. The meta-analysis was carried out using Rev Man software V5.4. A total of eight studies were included in our systematic review. Pooled analysis showed that omecamtiv mecarbil is not associated with increased incidence of death, any adverse events, hypotension, heart failure, ventricular tachyarrhythmia, dyspnea, dizziness, and serious adverse events. Regarding the efficacy, omecamtiv mecarbil significantly reduced heart rate with some studies demonstrating its significant improvement in left ventricular ejection fraction and systolic function. Conclusion: Omecamtiv mecarbil is a well-tolerated drug in heart failure patients. The limited data regarding the efficacy suggested that it may improve ejection fraction and systolic function.
