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-...

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...

Retrograde coronary aortic dissection is a rare but dangerous complication of coronary angioplasty. Mostly seen in right coronary artery procedures, especially in chronic total oclussion lesions, and rarely seen in left side procedures. This is a case report of an aortic dissection complicated by coronary angioplasty of the left circumflex artery. Immediate stenting of the left main coronary ar...

Objectives. We hypothesized that atherectomy would be superior to balloon angioplasty for ostial and nonostial left anterior descending coronary artery lesions. Background. Balloon angioplasty of ostial coronary artery lesions has been associated with a lower procedural success rate and a higher rate of complications and of restenosis than angioplasty of nonostial stenoses. Directional coronary...

Inappropriate percutaneous transluminal coronary angioplasty of the anterior descending artery was avoided in a 52-year-old woman when the intracoronary administration of glyceryl trinitrate immediately before the angioplasty disclosed the organic component of the supposedly fixed, critical (80%) stenosis to be less than 50% of the lumen diameter. The spastic component of the stenosis had not b...
