Treatment of rats with bindarit (200 mg/kg/day) significantly reduced balloon injury-induced neointimal formation by 39% at day 14 without affecting re-endothelialisation and reduced the number of medial and neointimal proliferating cells at day 7 by 54% and 30%, respectively. (unina.it)

BACKGROUND: Stent design and technological modifications to allow for anti-proliferative drug elution influence restenosis rates following percutaneous coronary intervention (PCI). (ox.ac.uk)

1996) Patterns and Mechanisms of In-Stent Restenosis. (scirp.org)
In an effort to improve on current therapy for restenosis we are prompted to consider new strategies for prevention and treatment, focusing on understanding of molecular mechanisms and identifying possible therapeutic targets. (unina.it)
open the intriguing possibility that other, unknown CD54-dependent mechanisms play a role in restenosis. (iiarjournals.org)

ASPs for both peripheral and coronary were stable and better than forecast. (nasdaq.com)

Administration of fisetin (ip 3 mg/kg daily for 2 weeks) right after the injury significantly increased PON2 expression in the artery, inhibiting ROS production, and efficiently reduced carotid neointimal hyperplasia. (hindawi.com)
Neointimal hyperplasia after vascular injury plays a critical role in the process of vascular restenosis, but the mechanism has not been fully elucidated yet [ 3 ]. (hindawi.com)
Administration of LABR-312 at the time of PCI will reduce restenosis compared with placebo as assessed by the OCT endpoint of % neointimal hyperplasia (%NIH) volume at 9 months in patients with DM. (vchri.ca)

Objective:We examined the effects of peri-procedural intensive glycemic control (IGC) during early percutaneous coronary intervention (PCI) on restenosis rate in hyperglycemic patients with ST-segment elevation myocardial infarction (STEMI).Research Design and Methods:A total of 165 hyperglycemic patients (glucose ≥140 mg/dl) with first STEMI undergoing PCI were studied.

Although a reduction in the percentage of subjects developing restenosis has been observed at the same time PCA has evolved, in-stent restenosis (ISR) continues to be one of the main complications in patients undergoing this procedure [ 2 ]. (hindawi.com)
