24 Hour Ambulatory Cardiac Oxygen Consumption

Status Completed

Clinical Trial Summary

A randomized,double-blind,double-dummy,active controlled,15 week study to evaluate the effects of nebivolol and valsartan alone and in combination on 24-hour ambulatory cardiac work and variability of heart rate-mean central systolic pressure product.

Clinical Trial Description

Subjects with hypertension (systolic blood pressure (SBP) >140 or diastolic blood pressure (DBP)>90, n=26) were studied using a double-blinded, forced-titration, sequence-controlled, crossover design with 3 experimental periods: Valsartan 320, nebivolol 40, and nebivolol/valsartan 320/40 mg daily. After 4 weeks of each drug, ambulatory pulse wave analysis (IEM MobilOGraph) was performed every 20 min for 24-hours. The primary hypothesis was that nebivolol/valsartan combination therapy would be superior to valsartan monotherapy in reducing mean 24-hour mean myocardial oxygen consumption determined by 24-hour ambulatory heart rate-central systolic pressure product [ACRPP]. A secondary hypothesis was that the combination would also reduce the variability of 24-hour myocardial oxygen consumption. ;
