Abstract:
This was a case-control, cross-sectional prospective study. A total of 116 patients with systemic hypertension, and 116 healthy controls over 45 years of age, were included. Subfoveal choroidal thickness (SFCT) was measured using a Heidelberg SD-OCT platform operating in the enhanced depth imaging mode. Patients were also subjected to 24-h ambulatory blood pressure monitoring (ABPM) and standard transthoracic echocardiography (STTE). Patients were divided into dippers and nondippers using ABPM data and those with or without left ventricular hypertrophy (LVH+ and LVH-) based on STTE data. The elastic parameters of the aorta, thus aortic strain (AoS), the beta index (BI), aortic distensibility (AoD), and the left ventricular mass index (LVMI), were calculated from STTE data.
