Completed
Conditions
Arterial Hypertension
Registration Number
NCT03006796
Lead Sponsor
Russian Heart Failure Society
Brief Summary

This is an observational prospective study of azilsartan medoxomil / chlorthalidone compared with irbesartan / hydrochlorothiazide in routine therapy of patients with arterial hypertension and obesity.

Detailed Description

Observational Prospective stUdy of aZilsartan medoxomil/ chlorthalidone compared with irbesartan/hydrochlorothiaZide combination therapy in patients with arteriaL hypertension and obEsity in routine clinical practice (PUZZLE).

The study population is 94 patients with untreated or poorly controlled arterial hypertension and obesity.

The main inclusion criteria are:

1. Male and female 35-55 year old.

2. Diagnosis of essential arterial hypertension I-II grade.

3. Patients with obesity (BMI ≥ 30 kg/m²)

4. Patients with untreated arterial hypertension (clinic SBP ≥ 140 mmHg, DBP ≥ 90 mmHg and no previous antihypertensive treatment.

5. Patients with poorly controlled arterial hypertension (clinic SBP ≥ 140 mmHg, DBP ≥ 90 mmHg on previous antihypertensive treatment.

6. Written informed consent.

The main exclusion criteria are:

1. Patients with symptomatic organ damage (myocardial infarction, stroke, angina pectoris, chronic kidney disease ≥ 4 grade, diabetes).

2. Patients with secondary arterial hypertension.

3. Patients with intolerance of angiotensin II receptor blockers, thiazide diuretic.

4. Patients with contraindication to study drugs in accordance with Russian instruction.

5. Patients currently enrolled in other clinical trials. The treatment period is 6 months. The study plan includes 4 basic and 1 additional visits are planned: initial visit, 3 follow-ups (including additional) and study-end visit.
