Method of treating dyspnea associated with acute heart failure

Abstract

The disclosure pertains to methods of reducing decompensation through acute intervention including in subjects afflicted with acute decompensated heart failure. Particularly, the disclosure provides methods for treating acute cardiac decompensation by administering a pharmaceutically effective amount of relaxin.

We claim: 
     
         1 . A method of reducing death from cardiovascular causes in a hypertensive or normotensive human subject with acute heart failure comprising administering a therapeutically effective amount of a pharmaceutically active H2 relaxin to the subject. 
     
     
         2 . The method of  claim 1  wherein fewer deaths from cardiovascular causes occur by day 180 in subjects administered relaxin than in subjects administered placebo. 
     
     
         3 . The method of  claim 2  wherein fewer deaths from cardiovascular causes occur by day 60 in subjects administered relaxin than in subjects administered placebo. 
     
     
         4 . The method of  claim 3  wherein fewer deaths from cardiovascular causes occur by day 30 in subjects administered relaxin than in subjects administered placebo. 
     
     
         5 . A method of reducing renal impairment in a hypertensive or normotensive human subject with acute heart failure comprising administering a therapeutically effective amount of a pharmaceutically active H2 relaxin to the subject. 
     
     
         6 . The method of  claim 5  wherein the incidence of renal impairment is reduced to less than or equal to about 5%. 
     
     
         7 . The method of  claim 5  wherein the renal impairment comprises renal failure. 
     
     
         8 . The method of  claim 5  wherein the renal impairment comprises a rise in serum creatinine. 
     
     
         9 . The method of  claim 8  wherein the serum creatinine level on day five is lower in subjects who were administered relaxin than in subjects who were administered a placebo. 
     
     
         10 . The method of  claim 8  wherein serum creatinine increases of more than about 0.5 mg/dl occur in fewer subjects who were administered relaxin than in subjects who were administered a placebo.
