We suppposed that MHR could demonstrate not just systemic artheriosclerosis, but also local artheriosclerosis. With the addition of the local changes at the near of the MB atherosclerosis could be started earlier. There are some limitations in our study. It was conducted with a small population, and it is a single-center study. Since we measured MHR only at baseline, serial MHR changes were not assessed. A prognostic value of MHR for MB was not 15
