Methods Patients (128 cases) with dilated cardiomyopathy in the Sixth People's Hospital of Nantong from November 2016 to June 2019 were divided in to observation group (64 cases) and control group (64 cases) according to random number table method. Patients in the control group was intravenously injected with Dobutamine Hydrochloride Injection at 5 μg/(kg·min) for 24 h on the basis of conventional treatment. On the basis of conventional treatment, patients in the observation group was given Levosimendan Injection with an initial loading dose of 6-12 μg/kg, the infusion time was longer than 10 min, followed by intravenous pumping 0.05-0.2 μg/(kg·min) for 24 h. 7 days as a course of treatment, two groups were treated for 1 course. The clinical effects of two groups were observed, and the indexes of cardiac function, myocardial mechanics, and serology before and after treatment were compared.Results After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). After treatment, LVESV and LVEDV in two groups were significantly decreased, but the LVEF were increased (P<0.05). And LVESV and LVEDV in the observation group were significantly lower than those in the control group, LVEF were higher than those in the control group (P<0.05). After treatment, GLS, GRS, and GAS in two groups were significantly increased (P<0.05). And GLS, GRS, and GAS in the observation group were significantly higher than those in the control group (P<0.05). After treatment, Gal-3, β2-MG, and sST2 in two groups were significantly decreased (P<0.05). And the levels of Gal-3, β2-MG, and sST2 in the observation group were significantly lower than those in the control group (P<0.05). Conclusion Levosimendan in treatment of dilated cardiomyopathy can significantly improve the cardiac function and myocardial contractility, inhibit the secretion of Gal-3, β2-MG, sST2, and improve the efficacy, safety and reliability, it is worth recommending in the clinical treatment of patients with dilated cardiomyopathy."/>
