Therapeutic Development of Levosimendan in Acute and Advanced Heart Failure: A Systematic Review

Levosimendan (LS) has been progressively used for the treatment of patients developing acute as well as chronic or advanced cardiac dysfunction. It has proven to be a better inotropic agent than its counterparts in terms of its ability to increase the cardiac output in an acutely or chronically decompensated heart without an increase in the myocardial oxygen demand. The purpose of this systematic review, which was carried out in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020, was to determine the efficacy and advantages of utilizing LS in patients with both acute and chronic heart failure. We collected and reviewed articles, including clinical trials, literature reviews, randomized and non-randomized control trials, case-control and cohort studies, and systematic reviews and meta-analyses published between January 1, 2012, and November 27, 2022. The databases that were used to collect these articles included Pubmed, Pubmed Central, Cochrane Library, and Google Scholar. After applying appropriate filters, a total of 143 reports were identified from these four databases. They were further screened and subjected to quality assessment tools which finally yielded 21 studies that were included in this systematic review. This review provides strong evidence that the pharmacological properties and different mechanisms of action of LS give it an upper hand over other inotropic agents for its successful administration in patients with either acute or advanced cardiac failure, which consists of left as well as right ventricular failure, either individually or in combination.
