The latest guidelines for the management of arterial hypertension, the silent killer, were published in summer 2023. They particularly emphasize again the quality of blood pressure measurement which ideally should always be automated using oscillometric device and an arm cuff already in the consulting room. They remind you how to manage the blood pressure of a patient whose hypertension has been confirmed, to stimulate drug compliance and to avoid therapeutic inertia. A holistic view of the patient with all his or her risk factors is always required. The general practitioner is the key player in the diagnosis, treatment and monitoring of the hypertensive patient whose therapeutic education has been as complete as possible with practice of self-measurement of blood pressure at home if possible. The goal is to normalize blood pressure within the first three months of treatment initiation and to reduce as much as possible the cardiovascular risk of the treated patient in the frame of preventive medicine.
