Coronary Palmaz-Schatz stent implantation in acute myocardial infarction.
OBJECTIVE To investigate the feasibility of coronary stenting in acute myocardial infarction. DESIGN Prospective observational study. PATIENTS 80 patients undergoing direct balloon angioplasty for acute myocardial infarction who had coronary Palmaz-Schatz stents implanted during a 3 year study period. Indications for stenting were abrupt reocclusion, large dissection with threatened reocclu...
متن کامل[Neointimal tissue proliferation after coronary stent implantation without predilatation].
INTRODUCTION AND OBJECTIVES Intravascular ultrasound (IVUS) studies in conventional stent angioplasty with predilatation have demonstrated that late luminal narrowing is caused by neointimal proliferation. In the present study, we analyzed the degree and distribution of in-stent neointimal proliferation after direct stent implantation and aimed to identify variables that predict a proliferative...
متن کاملCirculating monocytes and in-stent neointima after coronary stent implantation.
OBJECTIVES The aim of this study was to investigate the relationship between circulating monocytes and in-stent neointimal volume at six-month follow-up. BACKGROUND In-stent neointimal hyperplasia is the main contributing factor to in-stent restenosis. There is increasing evidence that white blood cells (WBCs), especially monocytes, play a central role in restenosis after stent implantation. ...
متن کاملCoronary rupture during stent implantation.
A 69-year-old patient with unstable angina presented to cardiac catheterization with a tight lesion in the mid right coronary artery (Figure 1A) and moderate lesions in the left main and left anterior descending coronary arteries. During coronary angioplasty, a stent was electively implanted in the right coronary artery, with good initial results. However, during subsequent aggressive, high-pre...
