Brief summary: The aim of study is to assess the angioprotective effects of antihypertensive combination therapy with perindopril 10 mg and moxonidine 0.4-0.6 mg in patients with arterial hypertension, metabolic syndrome, and obesity, who had Pulse Wave Velocity (PWV) \> 10 m/s on the previously administered two-component combination antihypertensive therapy.

Open-label non-comparative prospective study for 24 week for each patient.

Detailed description: According to European Society of Cardiology (ESC) and the European Society of Hypertension (ESH) Guidelines for the management of arterial hypertension 2018 in case of previous combination at full dose does not allow to achieve the target Blood Pressure (BP), that therapy might be switch to different two-drug combination.

The study will enroll 120 hypertensive (Grade 1, 2 Arterial Hypertension (AH): Systolic Blood Pressure (SBP) 140-179 mm Hg and Diastolic Blood Pressure (DBP) 90-109 mm Hg According to ESC/ESH Guidelines 2018) patients with metabolic syndrome who met the inclusion criteria when treated with Angiotensin Converting Enzyme Inhibition(ACEi) /Angiotensin Receptor Blocker (ARB) + hydrochlorothiazide (HCTZ)/indapamide or +amlodipine (30 patients in each group):

1. ACEi (except perindopril) + diuretic (HCTZ or indapamide)
2. ACEi (except perindopril) + amlodipine
3. ARB+ diuretic (HCTZ or indapamide)
4. ARB+ amlodipine

Upon obtaining Inform Consent the previous therapy will be discontinued according to recommendations (gradually or at once).

After 14 days of wash-out period perindopril 10 mg + moxonidine 0.4 mg a day will be prescribed.

If target BP is not achieved after 4 weeks, the dosage will increase up to perindopril 10 mg + moxonidine 0.6 mg a day (given as two divided doses).

FORBIDDEN TREATMENTS:

Any other antihypertensives (calcium antagonists, β-blockers, ACEi except perindopril, ARBs, diuretics) for routine AH management (except those used to resolve the uncontrolled hypertension).

CRITERIA FOR PREMATURE PATIENT WITHDRAWAL FROM THE STUDY:

1. Withdrawal of informed consent by the patient at any time of the study.
2. Need for uncontrolled hypertension management occurring more than 2 times weekly throughout the 2 consecutive weeks during study period.
3. Need for the third antihypertensive drug.

Eligibility criteria: Inclusion Criteria:

1. Patients (male and female) aging 18 to 70 years.
2. Grade 1, 2 AH (SBP 140-179 mm Hg and/or DBP 90-109 mm Hg according 2018 ESH/ESC guidelines)
3. PWV \> 10 m/s
4. Previous two-component antihypertensive therapy (ACEi/ARB+ diuretic (HCTZ or indapamide) or ACEI/ARB + amlodipine) during at least 6 months prior to the study enrollment
5. Metabolic syndrome diagnosed by the 2009 Russian Society of Cardiology (RSC) National Guidelines criteria

   1. THE MAIN SIGN: central (abdominal) obesity defined as waist circumference (WC) above 80 cm in women and above 94 cm in men.
   2. ADDITIONAL CRITERIA:

   i. - arterial hypertension (BP ≥ 130/85 mm Hg) ii. - high triglycerides (≥ 1.7 mmol/l) iii. - decreased HDL-cholesterol (\<1.0 mmol/l for men; \<1.2 mmol/l for women) iv. - increased LDL-cholesterol \> 3.0 mmol/l v. - fasting hyperglycaemia (fasting plasma glucose ≥ 6.1 mmol/l) vi. - impaired glucose tolerance (plasma glucose at 2 hours after glucose load from ≥7.8 to ≤11.1 mmol/l)

   Metabolic syndrome is defined as presence of central obesity and two of the additional criteria.
