- Brief Summary
The purpose of this study is to evaluate best medical management to achieve the BP goals of ESC/ESH (120-129 / 70-79 mmHg) in HT patients who are \<65 years old and ineffectively treated (BP ≥ 130/80 mg) with 3 or more antihypertensive drugs
- Detailed Description
Purpose: To evaluate best medical management to achieve the ESC/ESH 2018 BP goals of 120-129 / 70-79 mmHg in HT patients aged \< 65 y not controlled on 3 or more antihypertensive drugs.
Study design:
Phase A (Active screening) (n = 2500) 7 days Confirmation of the true ineffectiveness of antihypertensive therapy based on 3 or more antihypertensive drugs (single or dual drug preparations) using ABPM and home BP measurements.
Phase B (Open-label, non-randomized) (n = 1250) 12 weeks Replacement of ineffective antihypertensive treatment based on 3 or more antihypertensive drugs (single or dual drug preparations) with a triple single pill combination (SPC) based on optimally combined antihypertensive drugs: perindopril + indapamide + amlodipine (P+I+A) or olmesartan + hydrocholothiazide + amlodipine (O+H+A).
Phase C (Double blind, randomized, parallel-group) (n = 480) 24 weeks
Comparison of antihypertensive efficacy and tolerability profile:
* spironolactone
* eplerenone
* torasemide attached as an antihypertensive drug of 4th choice.
