A Case Demonstrating the Cardio-Vascular Interaction by a New Cardio-Ankle Vascular Index During the Treatment of Concentric Hypertrophy

A 42-year-old hypertensive woman came to our hospital suffering from shortness of breath. Her left ventricular mass index (LVMI) was increased, and a new arterial stiffness index, cardio-ankle vascular index (CAVI), was also elevated. By treating hypertension (HT), diabetes mellitus (DM) and obstructive sleep apnea (OSA), her left ventricular concentric hypertrophy was improved, accompanying with a decrease in CAVI. These observations suggested that arterial stiffness monitored with CAVI might be involved in cardiac hypertrophy. This cardio-vascular interaction could be demonstrated at the first time by monitoring CAVI, which is not affected by blood pressure (BP) at measuring time.
