Complications and predictors associated with persistent hemodynamic depression after carotid artery stenting

Abstract We aimed to investigate the complications and predictors associated with persistent hemodynamic depression (PHD) after carotid artery stenting (CAS). A total of 204 patients undergoing CAS in two centers between January 2011 and November 2013 were enrolled for study into two cohorts: PHD (systolic blood pressure p  = 0.001). Regression analysis revealed that diabetes, severe calcified plaque and a balloon dilation pressure of more than 8 atmospheres (atm) were the independent predictors for PHD after CAS. We concluded that PHD may be related to increased complications of CAS. Patients with diabetes, more severe calcified plaque and more balloon dilation pressure are more prone to develop PHD after CAS.
