Endothelial Injuries of Coronary Arteries Distal to Thrombotic Sites
Intracoronary thrombus formation is associated with epicardial vasoconstriction distal to the thrombotic site. To investigate the mechanisms of abnormal vasomotor function of the artery distal to the thrombotic site, we studied coronary vessels in dogs with cyclic flow variations (CFVs) of the left anterior descending coronary artery (LAD) stenosis with endothelial injury. Coronary rings isolat...
متن کاملCoronary endothelial dysfunction distal to stent of first-generation drug-eluting stents.
OBJECTIVES This study sought to evaluate the relationship between coronary endothelial function and neointimal coverage after drug-eluting stent (DES) implantation. BACKGROUND The mechanisms of endothelial dysfunction after DES implantation remain to be fully elucidated. We hypothesized that poor neointimal coverage after DES implantation may be associated with endothelial dysfunction distal ...
متن کاملAn advection-diffusion multi-layer porous model for stent drug delivery in coronary arteries
Arterial drug concentration distribution determines local toxicity. The safety issues dealt with Drug-Eluting Stents (DESs) reveal the needs for investigation about the effective factors contributing to fluctuations in arterial drug uptake. The current study focused on the importance of hypertension as an important and controversial risk factor among researchers on the efficacy of Heparin-Eluti...
متن کاملAbnormal vasomotor function of porcine coronary arteries distal to sirolimus-eluting stents.
OBJECTIVES This study sought to determine vasomotor functional responses of conduit coronary artery distal to bare-metal stents (BMS), polymer-only stents (POLY), and sirolimus-eluting stents (SES) in a clinically relevant animal model. BACKGROUND Drug-eluting stents (DES) reduce in-stent restenosis, and also affect neointima formation and vascular remodeling in downstream coronary segments. ...
متن کاملAltered reactivity of coronary arteries located distal to a chronic coronary occlusion.
The coronary vasculature located distal to a chronic occlusion (collateral-dependent) has been shown to exhibit altered reactivity to vasoactive agonists. Thus we evaluated effects of chronic coronary artery occlusion on vasomotor responsiveness of collateral-dependent arteries isolated from a canine model of Ameroid occlusion of the left circumflex (LCX) coronary artery. We compared in vitro r...
