E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the effects of nifedipine GITS and ramipril on different estimates of blood pressure variability (over 24 h, at home, between clinic visits) in subjects with elevated blood pressure variability. |
Comparare gli effetti di nifedipina GITS e di ramipril su vari indici di variabilità della pressione arteriosa (nelle 24 ore, a domicilio, tra visite ambulatoriali) in soggetti in cui variabilità della pressione arteriosa è elevata. |
|
E.2.2 | Secondary objectives of the trial |
To assess whether the degree of treatment-induced changes in blood pressure variability, is related to the degree of regression (or progression) of organ damage, after accounting for mean blood pressure reduction by treatment. |
Valutare se il grado di modificazioni di variabilità della pressione arteriosa indotte dai trattamenti utilizzati correla con il grado di regressione (o di progressione) del danno d’organo ipertensivo, tenendo conto delle riduzioni in valore medio della pressione arteriosa indotte dal trattamento. |
