Study Completion Date:	December 2011
Primary Completion Date:	June 2009 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: 1 Spironolactone	Drug: Spironolactone 25mg tablet daily for 9 months Other Name: Aldactone
Placebo Comparator: 2 Placebo	Drug: Placebo Placebo tablet daily for 9 months

Detailed Description:

Exercise intolerance due to HFPEF is a major cause of disability among older Americans. Several lines of evidence suggest that aldosterone antagonism may improve exercise tolerance in HFPEF. Therefore, the primary aim of this study is to test the hypothesis that spironolactone will improve exercise tolerance and quality of life in elderly patients with isolated HFPEF. A total of 72 participants aged 60 or older will be randomized to receive either spironolactone 25mg daily or a placebo.
