Plain English Summary
Background and study aims?
Despite best treatment for high blood pressure, blood pressure (BP) control is achieved in less than one third of the patients. The main reason is the low adherence of patients to the treatment and lack of awareness about high blood pressure and its consequences. The need to take many pills, several times a day, for a long time and possible side effects of drugs significantly reduce the number of patients who are treated continuously. Less effective treatment is also due to lack of simple step-by-step administration of a particular combination of drugs (Perindopril and Amlodipine) that can be effective in decreasing blood pressure, with low probability of side effects and the possibility of a single dose daily. Effective treatment can be reached when doctors make home visits to measure patients blood pressure. Self-monitoring of blood pressure by the patients between doctor visits also promotes adherence to treatment. The objective of this study is to see how good such a stepwise administration of treatment is along with BP monitoring at home and educating patients to keep to treatment.
Who can participate?
Patients with blood pressure more than 160/100mmHg if they have not been treated or more than 140/90mmHg if they have received therapy with one, two or three antihypertensive drugs can participate in the study.
What does the study involve?
The study includes patients aged 35 to 70, with high blood pressure and who are in the outpatient treatment. Patients visit the doctor for over 6 months. In the first visit, the doctor evaluates the patients demographic information, medical history, risk factors, information about the treatment conducted, blood pressure, heart rate and adherence to treatment by questionnaire. In addition, every participant of the study receives recommendations to alter their lifestyle and instructions for measuring blood pressure at home. The doctor conducts screening and decides on the inclusion of the patient in the trial, If included, their current treatment is stopped depending on the condition of the patient. The doctor chooses the drug combination (perindopril/amlodipine) according to initial blood pressure and presence of other diseases, where the patient may require an increased dose. In the second visit, doctor changes the therapy according to the results achieved by previous treatment. The effectiveness of the treatment using this combination of drugs is assessed using various parameters.
What are the possible benefits and risks of participating?
There is no immediate direct benefit to those taking part. All participants receive an additional teaching material regarding the procedure to be performed. Information obtained from this study may be helpful in future. By taking part in this study there are no risks of physical injury or harm to the participants.
Where is the study run from?
The PERFECT-BP study has been set up by the Cardiovascular Surgeons Association (Ukraine) and Kiev City Therapeutic Society (Ukraine).
When is study starting and how long is it expected to run for?
The study started in March 2012 and will run for one year or until the required number of patients have been recruited and evaluated
Who is funding the study?

If the patient previously was not treated, he is administered fixed combination of perindopril/amlodipine (Bi-Prestarium) in dose of 5/5 mg, 5/10 or 10/5 mg once per day. The doctor chooses the dose according to baseline blood pressure and comorbidity in patient who may require increased doses of Perindopril and Amlodipine. If the patient was treated before the doctor prescribes therapy according to its own judgment based on the algorithm of treatment that is detailed below. Prescription of drugs on each successive step is possible only after the prescription of treatment on the previous steps.
Step 1: prescribing Bi-Prestarium one tablet per day
Step 2: increasing dose of Bi-Prestarium to maximum tolerated
Step 3: prescribing indapamide retard (Arifon Retard) once per day
Step 4: prescribing Spironolactone 25 mg twice per day
Step 5: prescribing Moxonidine in dose of 0.2 mg to 0.6 mg per day or Doxazosin 4-8 mg per day
At the first visit the patient is prescribed also aspirin and statin on medical indications.
Second and subsequent visit: the doctor changes the therapy according to the results achieved by previous treatment by its decision based on the treatment algorithm that was discussed above.
Prescribing of drugs on each successive step is possible only after reaching the maximum tolerated dose of Bi-Prestarium and having ordered the treatment on previous steps.
Overall treatment for one patient is 12 months.
In the course of trial the deviation from the established dosage regimen scheme is not allowed. In the case where in the opinion of a physician there is a need to deviate from the appointed regimen scheme the patient should be excluded from the trial and substituted with another one.
Perindopril , Amlodipine, indapamide
Primary outcome measure
1. Percentage of the patients who had achieved BP (less than 140/90 mm Hg) and for diabetes pts . BP<135/85 mm Hg
2. Percentage of the patients who had achieved home BP (less than 135/85 mm Hg)
Secondary outcome measures
1.Compare the achievement of target office blood pressure with a frequency achievement of target home BP, according to an independent measurement of blood pressure
2. Frequency of achieving BP control (<135/80 mm Hg.) for self-measurement of home blood pressure
3. Dynamics of office SBP and DBP reduction
4. Assessment of tolerability: dynamics of the patient's side effect
5. Assessment of adherence: Dynamics of the patient`s compliance - patient compliance assessed by questionnaire test X. Girerd
1.Dynamic of average daytime and nighttime SBP and DBP assessed with ABPM
2. Dynamics of central systolic blood pressure and central pulse pressure dynamics
3. Dynamic of echocardiography indexes
4. Dynamics of pulse wave velocity
