The Office versus Ambulatory (OvA) study looked at cardiovascular risk over 5 years in 1,963 patients subdivided at baseline according to their 24-h mean ambulatory blood pressure and their office blood pressure.1 Overall, the risk of a cardiovascular event was 3.2-fold higher in patients with a 24-h mean SBP ≥135 mmHg compared with a 24-hour ambulatory SBP <135 mmHg.1 Even after adjusting for office blood pressure, a 24-h mean SBP ≥135 mmHg indicated a 1.3-fold higher risk.1 The 24-h mean blood pressure is therefore an important independent indicator of cardiovascular risk.1 Clement DL, et al.
