The relationship between ascending aortic diameter with left atrial functions and left ventricular mass index in a population with normal left ventricular systolic function

Abstract

AbstractAimAscending aortic dilatation is a common clinical issue. In the present study, we aimed to evaluate the relationship between ascending aortic diameter with left ventricular (LV) and left atrial (LA) functions, and LV mass index (LVMI) in a population with normal LV systolic function.MethodsA total of 127 healthy participants with normal LV systolic function took part in the study. Echocardiographic measurements were obtained from each subject.ResultsThe mean age of the participants was 43 ± 14.1 years and 76 (59.8%) were female. The mean aortic diameter of the participants was 32.2 ± 4.7 mm. A negative correlation was found between aortic diameter and LV systolic function (LVEF r = ‐.516, p < .001; Gls r = ‐.370). In addition, there was a strong positive correlation between aortic diameter with LV wall thicknesses, LVMI (r = .745, p < .001), and systolic and diastolic diameters. The relationship between aortic diameter and diastolic parameters was evaluated, a negative correlation with Mitral E, Em, E/A ratio, and a positive correlation with MPI, Mitral A, Am, E/Em ratio were found.ConclusionA strong correlation between ascending aortic diameter with LV and LA functions, and LVMI in individuals with normal LV systolic function.
