ObjectiveLimited data are available about risk factors for the progression of aortic stiffness in healthy population. We examined several risk factors as possible independent predictors of aortic stiffness progression among a population-based sample of US men.MethodsA total of 240 men (40-49 years) free of CVD at baseline from the Pittsburgh site of the ERA JUMP study were evaluated. Aortic stiffness was measured as carotid-femoral pulse wave velocity at baseline and after 4.6 ± 0.2 (mean ± SD) years of follow-up. Progression of aortic stiffness was evaluated as relative annual change in carotid-femoral pulse wave velocity (% change/year). Using linear regression, both baseline potential risk factors and their annual changes were evaluated as possible risk factors for aortic stiffness progression. Baseline age, follow-up time, race, heart rate, and medications use were forced in all models.ResultsDuring follow-up, relative to baseline level, aortic stiffness increased 0.3% ± 5.3% per year. In final models, the independent predictors of degree of aortic stiffness progression were lower levels of adiponectin (P = 0.03), higher levels of systolic blood pressure (P = 0.03), greater annual change in systolic blood pressure (P = 0.04), and alcohol consumption â¥Â 2 times/week (P = 0.02). Adiponectin levels within the third (9.8 μg/Ml â¤Â adiponectin < 13.0 μg/mL) and the fourth (adiponectin â¥Â 13.0 μg/mL) quartiles were associated with an improvement in relative annual aortic stiffness progression (P = 0.02, P = 0.01, respectively) compared to levels within the first quartile (adiponectin â¤Â 7.0 μg/mL).ConclusionAmong apparently healthy men, lower levels of baseline adiponectin could be a novel marker for greater risk of aortic stiffness progression. Longitudinal research is required to evaluate whether adiponectin change over time would have similar association with aortic stiffness progression.
⺠Lower level of baseline adiponectin was associated with greater aortic stiffness progression. ⺠Higher level and change in SBP were associated with greater aortic stiffness progression. ⺠Consuming alcohol â¥2 times/week may be associated with more progression in aortic stiffness.
