Levosimendan for Cardiac Patients Undergoing Major Abdominal Cancer Surgeries

Overview

The objective of this pilot study is to evaluate the efficacy and safety of preoperative administration of levosimendan in patients with chronic heart failure scheduled for major abdominal cancer surgery assuming the reduction of both perioperative morbidity and mortality.

Cardiac complications are one of the most common causes of perioperative morbidity and mortality in patients undergoing non-cardiac surgery. Heart failure (HF) is an established risk factor for postoperative cardiac complications and mortality. The risk for postoperative mortality following major non-cardiac surgery is twice as that of patients with coronary artery disease (CAD) without HF. HF occurs in 1% to 6% of patients after major surgery, the risk being higher, between 6% and 25%, in patients with pre-existing cardiac conditions such as CAD, prior HF or valvular heart disease. Cardiovascular disease and cancer are among the leading causes of mortality worldwide. The number of patients presenting with both diseases concomitantly is likely to increase. Cardiac patients undergoing major abdominal cancer surgeries with substantial fluid shift, blood loss and severe hemodynamic instability are at higher risk for perioperative HF.Therefore, preoperative optimization of such patients is of paramount importance. Unfortunately, guidelines for the perioperative management and preparation of such patients have not been proposed. Besides, the prophylactic use of inotropic agents for preoperative optimization of patients at high risk for HF remains controversial owing to their potential to jeopardize the myocardial oxygen supply-demand balance or to induce dysrhythmias with an assumed higher mortality. Levosimendan is a calcium sensitizer with a positive inotropic action that has been shown to safely improve cardiac performance and hemodynamics in HF patients without increasing the myocardial oxygen demand or causing dysrrhythmias. The perioperative use of levosimendan for optimization of patients with HF has been reported in few studies with promising results, mainly for cardiac patients undergoing cardiac surgeries. However, the role of levosimendan has not been thoroughly evaluated in patients with chronic heart failure (CHF) undergoing major cancer surgery. The purpose of this prospective study is to evaluate the safety and efficacy of preoperative administration of levosimendan in patients with CHF scheduled for major abdominal cancer surgery.
