What this trial is about
Study design: Prospective, multicentric, randomized, comparative study Study duration: between 4 and 19 weeks depending on the study group. Population: minimum 35 hypertensives (stage 1 or stage 2) participants divided into 3 groups depending on hypertension criteria. GROUP 1 = untreated hypertensives, stage 1 or stage 2; GROUP 2 = hypertensives, stage 1, who are taking antihypertensive monotherapy; GROUP 3 = hypertensives, stage 1 or stage 2, who are taking antihypertensive treatment that doesn't allow them to have controlled blood pressure. Device Under Test (DUT): Aktiia device Reference: HBPM (Aktiia cuff) Periods of treatment: For GROUPS 1 and 2, 2 weeks of treatment for each antihypertensive medication followed by a washout period of 2 weeks (3 antihypertensive medications in total with a fixed dose; medication intake order is randomly assigned). For GROUP 3, an individualized new antihypertensive medication will be prescribed during the consultation with the investigator that will be administered for 3 weeks.
