N2 - Background: Although, hypertension is common in adults with repaired coarctation of aorta (COA), there are no data about on-treatment blood pressure (BP), and its relationship to outcomes in this population. The purpose of this study was to determine the relationship between on-treatment BP and cardiovascular mortality in adults with repaired COA. Methods: Retrospective study of adults with repaired COA on antihypertensive therapy (n = 461, age 39 ± 11). All BP measurements obtained within the first 3 years were averaged to determine the on-treatment BP, and the patients were stratified into BP quartiles using the cut-off points from the guidelines. Results: Being in the upper systolic BP (SBP) quartiles (SBP 120-129, 130-139 and ≥140) was associated with higher risk of cardiovascular mortality (HR 1.05, 95%CI 1.01-1.07, HR 1.12, 95%CI 1.04 to 1.15 and HR 1.39, 95%CI 1.13 to 1.59), as compared to being the lowest SBP quartile. We observed a 7% increase in the risk of cardiovascular mortality for every 5 mmHg increase in SBP, and a 4% increase in risk of cardiovascular mortality for every 5 mmHg increase in DBP. Conclusions: Collectively, these data suggest that even s less severe form of hypertension SBP (120-129 mmHg) was not benign, and perhaps should be considered for antihypertensive therapy. A randomized controlled clinical trial is required to determine whether this group of patients (SBP 120 to 129 mmHg) would benefit from antihypertensive therapy, and to determine the optimal type and intensity of antihypertensive therapy in this population.
