Patients were randomized to either 25 mg per day of spironolactone or placebo and followed for 2 years each. The primary endpoint is time to the first episode of VT/VF. Secondary endpoints will include changes in health related quality of life, frequency of hospitalization, and in a subset of patients the effect of spironolactone on the ventricular effective refractory period measured through the ICD 3 months after starting the study medication. All data analyses will be conducted on intent to treat basis.\n\nMethods: Patients were recruited at the Portland VA ICD clinics, the Seattle VA ICD clinics, Oregon Health and Sciences University ICD clinics and the Little Rock, Arkansas VA ICD clinics. Randomization and drug preparation were done by the Portland VA Medical Center research pharmacy. For safety purposes serum potassium will be measured at 1, 2, 3, 6, 12, 18, and 24 months. Patients will undergo ICD interrogation to document the occurrence of ICD therapy for VT or VF and will be screened for potential drug side effects every 3 months during the study. Health related quality of life will be measured at baseline, 3, 6, 12, 18, and 24 months using Short Form Health Survey adapted for veterans (SF36V) Veterans Health Study Version, the Patients Concerns Assessment, and the Kansas City Cardiomyopathy Questionnaire.
