Aims: In adults with coarctation of the aorta (CoA), hypertension (HTN) is a common long-term complication. We investigated the prevalence of HTN and analyzed factors associated with HTN.
Methods and results: In the national register for congenital heart disease, 653 adults with repaired CoA were identified (mean age 36.9 +/- 14.4 years); 344 (52.7%) of them had HTN, defined as either an existing diagnosis or blood pressure (BP) >= 140/90 mmHg at the clinical visit. In a multivariable model, age (years) (odds ratio [OR] 1.07, CI 1.05-1.10), sex (male) (OR 3.35, CI 1.98-5.68), and body mass index (kilograms per square meter) (OR 1.09, CI 1.03-1.16) were independently associated with having HTN, and so was systolic arm-leg BP gradient where an association with HTN was found at the ranges of (10, 20] and >20 mmHg, in comparison to the interval <= 10 mmHg (OR 3.58, CI 1.70-7.55, and OR 11.38, CI 4.03-32.11). This model remained valid when all patients who had increased BP (>= 140/90 mmHg) without having been diagnosed with HTN were excluded from the analyses.
Conclusions: Hypertension is common in patients with previously repaired CoA and is associated with increasing age, male sex, and elevated body mass index. There is also an association with arm-leg BP gradient, starting at relatively low levels that are usually not considered for intervention.
