Abstract

Methods of (i) reducing morbidity and/or mortality in a human patient undergoing cardiac surgery; (ii) preventing, or reducing the risk of development of, LCOS in a human patient undergoing cardiac surgery; or (iii) reducing the risk of, intensity of, or occurrence of, one or more postoperative adverse events in a human patient undergoing cardiac surgery. The methods can involve (a) a first period of administering to the patient levosimendan for about 1 hour, in which the administration of levosimendan during the first period is initiated: (i) before skin incision for the cardiac surgery, and (ii) at an infusion dose of about 0.2 μg/kg/min; and (b) a second period of administering to the patient levosimendan for about 23 hours, in which the administration of levosimendan during the second period is initiated at an infusion dose of about 0.1 μg/kg/min.

Claims (28)

1 . A method of reducing morbidity and mortality in a human patient undergoing cardiac surgery, the method comprising:

(a) a first period of administering to the human patient levosimendan for about 1 hour, wherein the administration of levosimendan during the first period is initiated (i) before skin incision for the cardiac surgery, and (ii) at an infusion dose of about 0.2 μg/kg/min; and

(b) a second period of administering to the human patient levosimendan for about 23 hours, wherein the administration of levosimendan during the second period is initiated at an infusion dose of about 0.1 μg/kg/min.

2 . A method of preventing, or reducing the risk of development of, low cardiac output syndrome (LCOS) in a human patient undergoing cardiac surgery, the method comprising:

(a) a first period of administering to the human patient levosimendan for about 1 hour, wherein the administration of levosimendan during the first period is initiated (i) before skin incision for the cardiac surgery, and (ii) at an infusion dose of about 0.2 μg/kg/min; and

(b) a second period of administering to the human patient levosimendan for about 23 hours, wherein the administration of levosimendan during the second period is initiated at an infusion dose of about 0.1 μg/kg/min.

3 . A method of reducing the risk of, intensity of, or occurrence of one or more postoperative adverse events in a human patient undergoing cardiac surgery, the method comprising:

(a) a first period of administering to the human patient levosimendan for about 1 hour, wherein the administration of levosimendan during the first period is initiated (i) before skin incision for the cardiac surgery, and (ii) at an infusion dose of about 0.2 μg/kg/min; and

(b) a second period of administering to the human patient levosimendan for about 23 hours, wherein the administration of levosimendan during the second period is initiated at an infusion dose of about 0.1 μg/kg/min.

4 . The method of claim 1 , wherein the about 0.2 μg/kg/min infusion dose initiated during the first period is decreased to one or more lower infusion doses.

5 . The method of claim 4 , wherein the about 0.2 μg/kg/min infusion dose administered during the first period is decreased to about 0.1 μg/kg/min.

6 . The method of claim 5 , wherein the about 0.1 μg/kg/min infusion dose administered during the first period is decreased to about 0.05 μg/kg/min.

7 . The method of claim 1 , wherein the about 0.1 μg/kg/min infusion dose initiated during the second period is decreased to one or more lower infusion doses.

8 . The method of claim 7 , wherein the about 0.1 μg/kg/min infusion dose initiated during the second period is decreased to about 0.05 μg/kg/min.

9 - 15 . (canceled)

16 . The method of claim 1 , wherein the cardiac surgery comprises coronary artery bypass graft (CABG) surgery, CABG with aortic valve surgery, CABG with mitral valve surgery, or isolated mitral valve surgery.

17 . The method of claim 1 , wherein the cardiac surgery is with a cardiopulmonary bypass.

18 - 48 . (canceled)

49 . The method of claim 2 , wherein the about 0.2 μg/kg/min infusion dose initiated during the first period is decreased to one or more lower infusion doses.

50 . The method of claim 49 , wherein the about 0.2 μg/kg/min infusion dose administered during the first period is decreased to about 0.1 μg/kg/min.

51 . The method of claim 50 , wherein the about 0.1 μg/kg/min infusion dose administered during the first period is decreased to about 0.05 μg/kg/min.

52 . The method of claim 2 , wherein the about 0.1 μg/kg/min infusion dose initiated during the second period is decreased to one or more lower infusion doses.

53 . The method of claim 52 , wherein the about 0.1 μg/kg/min infusion dose initiated during the second period is decreased to about 0.05 μg/kg/min.

54 . The method of claim 3 , wherein the about 0.2 μg/kg/min infusion dose initiated during the first period is decreased to one or more lower infusion doses.

55 . The method of claim 54 , wherein the about 0.2 μg/kg/min infusion dose administered during the first period is decreased to about 0.1 μg/kg/min.

56 . The method of claim 55 , wherein the about 0.1 μg/kg/min infusion dose administered during the first period is decreased to about 0.05 μg/kg/min.

57 . The method of claim 3 , wherein the about 0.1 μg/kg/min infusion dose initiated during the second period is decreased to one or more lower infusion doses.

58 . The method of claim 57 , wherein the about 0.1 μg/kg/min infusion dose initiated during the second period is decreased to about 0.05 μg/kg/min.
