Abstract

Ambulatory blood pressure monitoring (ABPM) is now considered the gold standard to evaluate BP, and predicts related cardiovascular risk. However, no study has reported the association of long-term changes in ABPM with the incidence of cardiovascular events, therefore the objective of this work. We included patients from the Bordeaux cohort of hypertensive patients, who had undergone at least two ABPM; the first was performed before or after antihypertensive treatment was started, and the second was the last recording available before any cardiovascular event. We included 591 patients (mean age, 54 years) with a 7-year average interval between the first and last ABPM, a 10-year average follow-up, and a total of 111 cardiovascular events. The patients were divided into four groups: G0, first and last 24 h systolic blood pressure (SBP) < 130; G1, first 24 h SBP ≥ 130, last 24 h SBP < 130; G2, first 24 h SBP < 130, last 24 h SBP ≥ 130; and G3, first 24 h SBP ≥ 130, last 24 h SBP ≥ 130 mmHg. Baseline ABPM better predicted future events than the last ABPM. G0 and G2 had similar survival. G1 and G3 had a worse prognosis than G0 and G2, while G1 had an intermediate risk between G0 and G3, indicating some benefit of treatment. In conclusion, our study showed the prognostic value of the first ABPM recorded in hypertensive patients and the persistence of risk when 24 h BP is controlled by antihypertensive treatment.
