Extracellular matrix changes in stented human coronary arteries.
BACKGROUND Restenosis after stenting occurs secondary to the accumulation of smooth muscle cells (SMCs) and extracellular matrix (ECM), with the ECM accounting for >50% of the neointimal volume. The composition of the in-stent ECM has not been well characterized in humans. METHODS AND RESULTS Postmortem human coronary arteries (n=45) containing stents underwent histological assessment of neoi...
متن کاملRelation between coronary artery remodelling (compensatory dilatation) and stenosis in human native coronary arteries.
OBJECTIVES To investigate the contribution of plaque size and vessel remodelling to coronary artery stenosis and to assess the role of vessel shrinkage (negative remodelling) across a wide range of lesions. DESIGN Postmortem study of coronary remodelling in perfusion fixed hearts. SUBJECTS 24 men and 24 women who died suddenly with coronary artery disease. MAIN OUTCOME MEASURES Percentage...

متن کاملAspirate from human stented native coronary arteries vs. saphenous vein grafts: more endothelin but less particulate debris.
Stent implantation into atherosclerotic coronary arteries releases particulate debris and soluble substances that contribute to impaired microvascular perfusion. Here we addressed the potential for microvascular obstruction in patients with stenotic native right coronary arteries (nRCA) compared with saphenous vein grafts on right coronary arteries (SVG-RCA). We enrolled symptomatic, male patie...
متن کاملSpontaneous dissection of native coronary arteries.
CASES We present 13 consecutive cases presenting in Auckland, New Zealand from 1996–2001. The diagnosis was made by angiography in 12 of the patients and at necropsy in one patient. Eleven of the 13 patients were female with a mean age of 44 years (range 25–58 years). There was no excess of traditional risk factors. On presentation four of the 13 patients were not thought to have an ischaemic p...
