24-hour Ambulatory Blood Pressure Monitoring in Patients With Blood Pressure Above Thresholds in General Practice

High blood pressure (HBP) is a major modifiable cardiovascular risk factor which prevalence is gradually increasing. Reducing blood pressure (BP) significantly decreases cardiovascular morbi-mortality. Nevertheless, BP control remains insufficient: only 51% of French patients using antihypertensive drugs achieve the BP control targets. HBP is mostly diagnosed and managed in primary care. Nevertheless, office BP measurements are unreliable for BP control and poorer predict target organ damage. Ambulatory BP measurements are recommended for HBP diagnosis and follow-up. 24-hour ambulatory blood pressure monitoring (ABPM) is the most cost-effective strategy. Its superiority has been demonstrated for HBP diagnosis and cardiovascular prognosis. In France, ABPM is poorly available and little studied in primary care. Therefore, the investigators conducted a regional prospective study to analyze the feasibility and benefits of ABPM among primary care hypertensive patients in daily practice.
