ValsartanPlacebo to valsartanFor the first week of the 8 week treatment period, patients received valsartan 160 mg, placebo to valsartan, and 2 tablets of placebo to aliskiren. For the remaining 7 weeks of the study, patients received valsartan 320 mg (two 160 mg capsules) and 2 tablets of placebo to aliskiren. The tablets and capsules (2 of each) were taken orally once daily each morning. To evaluate a missed dose, the last dose of medication was administered at the clinic, and the patient was scheduled to return 2 days later for exercise testing (8 weeks + 2 days).
AliskirenAliskirenFor the first week of the 8 week treatment period, patients received aliskiren 150 mg, placebo to aliskiren, and 2 capsules of placebo to valsartan. For the remaining 7 weeks of the study, patients received aliskiren 300 mg (two 150 mg tablets) and 2 capsules of placebo to valsartan. The tablets and capsules (2 of each) were taken orally once daily each morning. To evaluate a missed dose, the last dose of medication was administered at the clinic, and the patient was scheduled to return 2 days later for exercise testing (8 weeks + 2 days).

Primary Outcome Measures
NameTimeMethod
Change in Resting vs. Peak Heart Rate Systolic Blood Pressure (SBP) From Baseline to Week 8 After a Missed DoseBaseline and Week 8 + 2 days (48-hours after the last dose; 24 hours after a missed dose). Blood Pressure measurements were taken at rest and at peak heart rate at both timepoints.

The difference in resting vs. peak (85% of maximal predicted) heart rate (HR) SBP was calculated by measuring SBP before and during exercise on a standardized treadmill test, conducted according to the Bruce Protocol. Treadmill speed and incline were increased every 3 minutes until the patient was exhausted or peak HR was reached. The SBP at rest vs peak HR was recorded at Baseline and at Week 8 + 2 days (24-hrs after a missed dose); the change in rest vs. peak SBP between these timepoints is reported. The analysis included the rest to peak increase in SBP at baseline as a covariate.
