New-onset diabetes (NODAT) after solid organ transplantation is an important clinical challenge associated to increased risk of cardiovascular (CV) events. In end-stage renal disease (ESRD) patients, the impact of arterial stiffness on all-cause and CV mortality has been clearly documented. Arterial stiffness has a pivotal role in the genesis of high blood pressure (SBP), increased left ventricular hypertrophy (LVH), and consequently CV mortality. Both LVH and arterial stiffness are independent determinants of CV disease in patients with ESRD. The aim of this study is to evaluate the relationship between post-transplant new-onset diabetes and arterial stiffness and left ventricular mass index (LVMI) in kidney transplant recipients.
