Abstract

Morning blood pressure surge is associated with increased cardiovascular risk, possibly due to its ability to reflect short-term BP variability and/or its link with arterial stiffness. The link between morning BP surge and vascular stiffness is not defined.

689 untreated hypertensives (48±10 years, BP 149/92±17/10 mmHg) underwent c-f PWV and 24-h ambulatory BP measurement. Morning surge was calculated as: sleep-trough surge (STS, 2-hour average SBP after wake-up minus average of 3 SBP centered on the lowest nighttime reading), pre-awakening surge (PAS, 2-hour average SBP after wake-up minus 2-hour average SBP before wake-up), and rising BP surge (RBS, SBP on rising minus the lowest SBP in the 30’before). Average real variability (ARV, 24h average of the absolute differences between consecutive SBP), was considered a measure of short-term SBP variability.

STS and RBS were directly correlated to cfPWV (r=0.17 and r=0.12,p<0.01) and ARV (r=0.28 and r=0.23,p<0.001), while PAS had no such relationships. Patients in the top quartile of STS (>39 mmHg) had higher age- and 24-h mean BP-adjusted cfPWV (9.73±2 vs 9.29±2 m/s, p=0.004), while no difference was found for the top quartile of PAS or RBS. In a multivariate regression, high STS values predicted a high cfPWV (β=0.08,p=0.038), independently of age, sex, 24-h mean BP and nocturnal BP reduction. After adding ARV (β=0.17,p<0.001) to the model, the relationship between STS and cfPWV was no longer significant (β=0.05,p=0.17).

Morning SBP surge, calculated as STS, has a positive relation with aortic stiffness in hypertension, which is no longer significant after adjusting for 24-h short-term BP variability.
