Abstract

Aim:We sought to assess the long-term changes in aortic root diameter in a population-based sample, focusing on new-onset aortic root dilatation, as well as on the demographic and clinical variables independently related to this dynamic process.Methods:A total of 1122 participants with measurable echocardiographic parameters at baseline and after a 10-year follow-up were included in the analysis. Sex-specific upper limits of normality for absolute aortic root diameter, aortic root diameter indexed to body surface area (BSA) and to height were derived from 712 healthy normotensive PAMELA participants.Results:Over the 10-year follow-up, new aortic root dilatation occurred in 3.4% (aortic root /BSA), 4.4% (aortic root /height) and 7.3% (absolute aortic root), respectively. No substantial relationship was observed between baseline office and ambulatory blood pressure (BP) or their changes over time and incident aortic root /BSA and aortic root /height dilatation. Baseline aortic root diameter and left ventricular mass index (LVMI) emerged as important predictors of aortic root dilation, regardless of the diagnostic criteria used. This was also the case for the 10-year change in LVMI. The strength of association between nonhemodynamic variables and new-onset aortic root dilatation was variable, depending on the definition of the aortic phenotype.Conclusion:The incidence of aortic root dilatation in a general middle-aged population is a relatively infrequent but not so rare event and scarcely influenced by both office and out-office BP. On the contrary, it is strongly related to LVMI (and its variations over time). From a clinical perspective, this underlines that LVH prevention and regression can reduce the risk of aortic root dilatation in the community.
