Abstract

The aim of this study was to compare blood pressure rise after interruption of two angiotensin converting enzyme (ACE) inhibitors in hypertensive patients. After a 2-week placebo run-in period, hypertensive patients were treated with either trandolapril 2 mg once daily or perindopril 4 mg once daily for 4 weeks in a double-blind design. A placebo was then administered for 1 week. Three periods of 1-week home self-measured blood pressure (SMBP) were programmed: end of placebo run-in period, end of treatment period, and final withdrawal placebo period. Every day, three consecutive measurements were requested both in the evening and in the morning. Individual reversion to baseline BP level was studied in the subgroup of patients responding to therapy (evening diastolic SMBP decrease > or =6 mm Hg). The ratio (R) of mean post-drug DBP lowering (residual effect) over evening on-drug DBP lowering (full effect) was used to study reversion to baseline. Patients exhibiting a lower value than the median of this ratio were called Reverters, whereas others were called Nonreverters. One hundred-nineteen patients entered the analysis. During the treatment period, mean SMBP decreased significantly, from 150 +/- 14/97 +/- 7 mm Hg to 139 +/- 15...Continue Reading
