Abstract
En 中文
Routine assessment of abdominal aorta (AA) is not currently advised by the available guidelines, although hypertension is a major risk factor for the development of AA aneurysm. In the present study, we assessed correlations and predictive factors of AA dimension in a cohort of hypertensive patients. 3083 Patients ≥ 18 years old with available AA ultrasound were included. AA dilatation was defined as an AA diameter ≥ 25 mm. Correlations of AA dimension and dilatation with demographics and metabolic profile were explored. Multivariable regression was also used to identify potential confounders influencing univariate correlations. To evaluate the prognostic impact of AA dilatation a propensity score model was implemented, and survival probability curves were constructed using the Kaplan-Meier method. Increased AA diameter was independently associated with older age, male sex, active smoking, higher diastolic and lower systolic blood pressure, higher LV mass index and aortic root dimension and less use of β-blockers at baseline (all p < 0.05). A significant effect of baseline use of β-blockers and calcium channel blockers therapy were found (all p < 0.01). During a mean follow-up of 4.76 ± 2.91 years, 32 MACE occurred. Kaplan-Meier analysis showed that having AA ≥ 25 mm is associated with significant risk of MACE compared to patients with AA < 25 mm. AA remodeling is strongly influenced by the cardiovascular (CV) risk profile and hypertension mediated target organ damage and AA dilatation contributes to increased CV risk in treated hypertensive patients.
