Low-Dose Dobutamine and Single-Dose Tocilizumab in Acute Myocardial Infarction With High Risk of Cardiogenic Shock

Summary

In the present study, we aim to investigate the effects of dobutamine infusion and/or a single intravenous (IV) dose of the IL-6 antagonist Tocilizumab administered after percutaneous coronary intervention (PCI) to patients with acute myocardial infarction (AMI) presenting \< 24 hours from onset of chest pain and an intermediate to high risk of cardiogenic shock (CS) by assessment with the ORBI risk score (≥10 - not in overt shock at hospital admission). Plasma concentrations of pro-B-type natriuretic peptide (proBNP) as a proxy for development of cardiogenic shock (CS) and hemodynamic instability will be sampled for primary endpoint analysis. Effects on clinical parameters, mortality, morbidity as well as specific indicators of inflammation, cardiac function, and infarct size will secondarily be assessed noninvasively. The rationale behind the current study is that inflammatory and neurohormonal responses are associated with subclinical hemodynamic instability in patients with AMI with high risk of CS have worse outcomes. The potentially unstable condition may be targeted pharmacologically as an add-on to existing therapy. This is investigated in patients at elevated risk of CS by sampling biomarkers reflecting the inflammatory and neurohormonal responses, as well as determining effects on patient outcomes and infarct size.
