Association Between Local Ascending Aortic Elastic Properties and Left Ventricular Global Longitudinal Strain in Patients with Multiple Sclerosis: A Cross-Sectional Case–Control Echocardiographic Study

Background/Objectives: Multiple sclerosis (MS) has been associated with subclinical cardiovascular involvement, including impaired myocardial deformation and increased arterial stiffness. However, the local elastic properties of the ascending aorta and their relationship with subclinical left ventricular (LV) longitudinal dysfunction remain insufficiently characterized in MS.
