Blood pressure-lowering effect of carotid artery stenting in patients with symptomatic carotid artery stenosis

Background In patients with symptomatic carotid artery stenosis, long-term effects of carotid artery stenting (CAS) on blood pressure (BP) changes have not been documented well. We evaluated the effects of CAS on BP and found out its predisposing factors in patients with symptomatic carotid artery s...

Description
Summary:Background In patients with symptomatic carotid artery stenosis, long-term effects of carotid artery stenting (CAS) on blood pressure (BP) changes have not been documented well. We evaluated the effects of CAS on BP and found out its predisposing factors in patients with symptomatic carotid artery stenosis. Methods Between January 2003 and June 2012, a total of 107 patients were recruited, and all subjects met the following inclusion criteria: (1) patients underwent CAS with symptomatic carotid artery stenosis > 50 %; (2) patients had clinical and radiographic data for at least 1 year of follow-up after CAS; and (3) patients had BP measurements at four different time points: pretreatment, post-treatment, 1-month follow-up, and 1-year follow-up. We evaluated the significance of the BP changes between the pretreatment BP and follow-up BPs, and determined its predisposing factors. Results Compared to the mean systolic/diastolic BP value (141.0/87.4 mmHg) at the pretreatment BP, the follow-up BPs were significantly decreased after CAS (120.5/74.5, 126.2/76.9, and 129.2/79.0 mmHg at the post-treatment, the 1-month follow-up, and the 1-year follow-up, respectively [ p
