Background. Several studies suggest that repeated percutaneous transluminal coronary angioplasty procedures at the same site are associated with a progressively increasing risk of further restenosis and that short time intervals between successive procedures are predictive of future restenoses. Methods and Results. We assessed by quantitative coronary angiography the angiographic probability of...

BACKGROUND Coronary-stent placement is a new technique in which a balloon-expandable, stainless-steel, slotted tube is implanted at the site of a coronary stenosis. The purpose of this study was to compare the effects of stent placement and standard balloon angioplasty on angiographically detected restenosis and clinical outcomes. METHODS We randomly assigned 410 patients with symptomatic cor...

OBJECTIVES This study was conducted to assess whether coronary stenting produces better results compared with balloon angioplasty in patients with acute myocardial infarction (AMI) after failed thrombolysis. BACKGROUND Little evidence exists on the value of rescue mechanical reperfusion after failed thrombolysis. METHODS This open-label, randomized study enrolled 181 patients with AMI refer...

thrombotic thrombocytopenic purpura (ttp) is a rare syndrome affecting multiple organs. there is no sufficient evidence regarding the clinical cardiac manifestations of ttp. nonetheless, pathologic cardiac involvement is quite frequent in acute ttp, which is predominantly manifested as myocardial necrosis due to coronary arteriolar microthrombosis. the present case report describes a 43-year-ol...

OBJECTIVES The aim of this study was to investigate the relation between coronary atherosclerotic plaque injury and activation of the coagulation cascade. BACKGROUND Thrombus formation after atherosclerotic plaque disruption has been implicated in the pathogenesis of atherosclerosis, unstable angina and myocardial infarction. METHODS Biochemical markers of thrombin generation (prothrombin f...

The Council on Clinical Cardiology of the International Society and Federation of Cardiology has formed several task forces with the World Health Organization in recent years to provide guidelines and recommendations where confusion exists but there is sufficient experience for conclusions to be generalized by international experts. In November 1984, the council recommended that a task force be...

Introduction: Post-dilatation is associated with a simultaneous expansion of the stents that enhances the angioplasty outcomes. However, increased risk of mortality and morbidity has been reported in patients with acute myocardial infarction (AMI) which has provoked considerable controversies concerning its efficiency. Materials and Methods: During a two-...
