Eligibility
Inclusion criteria
Inclusion criteria: - Male and female subjects - Age 35-75 years - clinic systolic (SBP) =140 mmHg and/or diastolic blood pressure (DBP) = 90 mmHg - daytime blood pressure (BP) on ambulatory BP monitoring (ABPM) =135 mmHg systolic and/or =85 mmHg diastolic - home SBP standard deviation (SD) >7 mmHg and/or daytime ambulatory SBP SD >12 mmHg - patients may be included if untreated or, if treated with one antihypertensive drug or two drugs in low doses, after 2 weeks’ washout period - written informed consent to participate in the study Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 100 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 68
Exclusion criteria
Exclusion criteria: - subjects treated with = 2 antihypertensive drugs (except those on two drugs in low doses) - treated subjects with on-treatment clinic BP =160 mmHg systolic and/or 100 mmHg diastolic - treated antihypertensive subjects in whom withdrawal of treatment is deemed unethical for other reasons - Contraindications to study treatments as detailed in the relative Summaries of medical Product Characteristics for ramipril or nifedipine GITS (this includes hypersensitivity, pregnancy and lactation) - Cardiovascular diseases other than hypertension - Suspected or confirmed secondary hypertension - Diabetes mellitus - Other conditions deemed relevant by the investigator - BMI =35 kg/m2 - known severe obstructive sleep apnea - Premenopausal women not using effective contraceptive methods - Elevated probability of noncompliance with the study procedures
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: 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.;Secondary Objective: 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.;Primary end point(s): Variability (standard deviation) of home systolic blood pressure.;Timepoint(s) of evaluation of this end point: Final visit of the main study (10 weeks after randomization) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1) Variability (standard deviation) of home diastolic blood pressure. 2) Short term 24h variability of systolic blood pressure at final visit 3) Short term 24h variability of diastolic blood pressure at final visit 4) Visit-to-visit variability of systolic blood pressure assessed over the three last visits 5) Visit-to-visit variability of diastolic blood pressure assessed over the three last visits 6) Mean 24 hour systolic blood pressure at final visit;Timepoint(s) of evaluation of this end point: Secondary endpoints 1, 2, 3 and 6: Final visit of the main study (10 weeks after randomization) Secondary endpoints 4 and 5: The last three visits of the main study (6, 8 and 10 weeks after randomization) | — |
