OBJECTIVES The purpose of this study was to test if nitric oxide (NO) could improve microvascular perfusion and decrease tissue injury in a porcine model of myocardial ischemia and reperfusion (I/R). BACKGROUND Inhaled NO is a selective pulmonary vasodilator with biologic effects in remote vascular beds. METHODS In 37 pigs, the midportion of the left(More)
BACKGROUND Polymer coatings have been used to modify the surface of stents and to serve as a matrix for local drug delivery. METHODS Bare stainless steel stents or poly-bis-trifluorethoxy phosphazene (PTFEP) dip-coated stents (Coroflex, Germany) were randomly implanted into porcine coronary arteries with a balloon-to-artery ratio of 1.1-1.2 : 1. Scanning(More)
Medicinal herbs have been used over the past centuries for restoring the body’s homeostatic balance. Contemporary use of herbal supplements remains widespread in many cultures as treatment for specific ailments. Many possess cardiovascular actions, and some interact with cardiac medications. However, there is variable scientific evidence with respect to(More)
Reperfusion therapy for myocardial infarction is limited by significant re-occlusion rates and less-than-optimal myocardial tissue perfusion. It was the objective of this study to assess and compare the effect of ticagrelor, the first reversibly binding oral P2Y12 receptor antagonist, with that of clopidogrel, in conjunction with thrombolytic therapy, on(More)
The aim of this multicenter pilot study was to evaluate the acute safety and efficacy of the dexamethasone-eluting stent (0.5 microg/mm(2) of stent) implanted in patients with de novo single-vessel disease. This study included 71 patients, 42% of whom had unstable angina pectoris. An appropriately sized BiodivYsio Matrix Lo stent loaded with a total(More)
BACKGROUND In-stent restenosis may be prevented by impregnating an antiproliferative agent in a polymer from a stent platform. This approach requires both an antiproliferative agent effective in small doses and a biocompatible polymer. METHODS A series of new biodegradable elastomeric poly(ester-amide)(co-PEA) polymers having functional carboxyl groups(More)
Phosphorylcholine (PC)-coated stents have shown excellent blood and tissue biocompatibility in porcine coronary arteries. The purpose of this study was to determine the efficacy of local methylprednisolone (MP) delivery using PC-coated stents to inhibit inflammatory response and in-stent neointimal hyperplasia in an overstretched porcine coronary model.(More)
In-stent restenosis remains an unresolved problem which occurs in 5-20% of patients undergoing coronary stenting within the first 3-6 months. Neointimal formation is the main contributor to in-stent restenosis. Stent-induced arterial injury and peri-strut inflammation are involved in the process of neointimal formation by activating cytokines and growth(More)
Ample cell adhesion to scaffolds is essential for effective bone tissue engineering. Chitosan/hydroxyapatite (CS/HA) scaffolds with channel-shaped and spherically shaped pore morphologies were prepared via in situ compositing hybridization in combination with lyophilization. The sizes of channel-shaped and spherically shaped pores of the CS/HA scaffolds(More)
Adult mesenchymal stem cells (MSCs) have been shown to spontaneously express cardiac proteins (CP) in vitro and to improve cardiac function after transplantation into experimentally induced acute myocardial infarction (AMI). However, if these effects are the result of MSC cardiac differentiation or a mere cooperative cellular interaction is a matter of(More)
