Abstract/OtherAbstract:
Abstract Objectives: Levosimendan is an inodilator indicated for acute heart failure (AHF). Its vasodilatory and anti-ischemic effects are mediated by the opening of ATP-dependent potassium channels (KATP channels). Diabetes mellitus is common in AHF patients and sulfonylureas are often prescribed. Sulfonylureas act by blocking the KATP channels. An interaction between levosimendan and sulfonylureas has been shown in preclinical models and could be hypothesized in clinical practice. Design: We produced a pooled analysis of six randomized levosimendan trials (in total of 3004 patients of which 1700 were treated with levosimendan and 226 both with levosimendan and sulfonylureas) with the aim to study the influence of concurrent sulfonylurea treatment to the levosimendan effects. Invasive and non-invasive hemodynamics, biomarkers (BNP), adverse events related to myocardial ischemia, and survival were evaluated. Results: In our relatively small data set, we could not detect any clinically relevant interactions between the sulfonylureas and levosimendan. Similar decreases in systolic and diastolic blood pressure, pulmonary capillary wedge pressure and BNP, and similar survival and adverse event profiles were seen in sulfonylurea users and non-users exposed to levosimendan. Conclusions: Concomitant use of sulfonylureas with levosimendan does not attenuate the hemodynamic or other effects of levosimendan.
