Abstract

Aortic root dilatation has been proposed as hypertension-mediated organ damage (HMOD). Nevertheless, the role of the aortic root dilatation as a possible additional HMOD is still unclear since studies conducted so far are quite heterogeneous regarding the type of population analyzed, the aortic tract considered, and the type of outcomes accounted for. The aim of the present study is to assess whether the presence of aortic dilatation is associated with strong cardiovascular (CV) events (MACE: heart failure, CV death, stroke, acute coronary syndrome, myocardial revascularization) in a population of patients affected by essential hypertension. Four hundred forty-five hypertensive patients from six Italian hospitals were recruited as part of ARGO-SIIA study1. For all centers, follow-up was obtained by re-contacting all patients by telephone and through the hospital's computer system. Aortic dilatation (AAD) was defined through absolute sex-specific thresholds as in previous studies (41 mm for males, 36 mm for females). Median follow-up was 60 months. AAD was found to be associated with the occurrence of MACE (HR = 4.07 [1.81-9.17], p < 0.001). This result was confirmed after correction for main demographic characteristics such as age, sex and BSA (HR = 2.91 [1.18-7.17], p = 0.020). At penalized Cox regression, age, left atrial dilatation, left ventricular hypertrophy and AAD were identified as best predictor of MACEs and AAD resulted a significant predictor of MACEs even after correction for these confounders (HR = 2.43 [1.02-5.78], p = 0.045). The presence of AAD was found to be associated with an increased risk of MACE independently of for major confounders, including established HMODs.
