Diagnosis and Management of Arterial Hypertension for Algerian Patients in Current Medical Practice

Merinal Laboratoires1,027 enrolled

Overview

Blood pressure reduction and control are associated with reduced risk of stroke and cardiovascular disease. There is evidence that ambulatory blood pressure monitoring (ABPM) results more accurately reflect the risk of cardiovascular events than do office measurements of blood pressure. New international guidelines recognize the importance of ABPM which has an important and growing role in the diagnosis and in guiding antihypertensive therapy. In 2011 in the United Kingdom, the National Institute for Health and Care Excellence (NICE) recommended that ABPM be performed on all patients with suspected hypertension to confirm the diagnosis and reduce unnecessary treatment in people who do not have true hypertension. The aim of this observational study is to describe the utility of ABPM generally and specifically in the management of hypertension by Cardiologists in the Algerian context.

The primary Objective of this study is to assess the benefit of the ABPM in the diagnosis and management of arterial hypertension in by Cardiologists. The Secondary Objectives are: * To identify the conditions of usage of ABPM for the diagnosis of arterial hypertension, * To evaluate the blood pressure during the ABPM assessment and at 6 weeks of follow up * To describe the study population (socio-demography), * To describe the therapeutic stratégies and the compliance to treatment.

Outcomes

Primary Outcomes

Diagnosis of hypertension

Valid 24h-ABPM: blood pressure ≥ 140/90 mmHg

Time frame: At 24 hours after the inclusion in the study (Visit 2)

Secondary Outcomes

Patient Demography

Age, Sexe

Time frame: At the Inclusion in the study

Therapeutic Decison

* Initiation of antihypertensive therapy in naive patients if the dianosis of hypertension is confirmed. * Maintain, switch or adaptation of treatment in treated patients.

Time frame: At 24 hours after the inclusion in the study (Visit 2)

Self-measurement of Arterial blood Pressure

Measurement of arterial pressure performed by the patient and reported on a follow up diary. Both systolic and diastolic pressures will be collected.

Time frame: At 6 weeks after the inclusion in the study (Visit 3)

Evaluation of Compliance to treatment

Evaluation test based on the method developed by Xavier Girerd, consisting in 6 questions on the compliance. The rating is divised in three categories: Good compliant, moderate compliant or non compliant. according to Girerd et al.
