BACKGROUND Acute deterioration in renal function is a recognized complication after coronary angiography and intervention. OBJECTIVES The goal of this study was to determine the impact on acute and long-term mortality and morbidity of contrast-induced deterioration in renal function after coronary intervention. METHODS We studied 439 consecutive(More)
Acute renal failure requiring dialysis is a rare but serious complication after percutaneous coronary interventions (PCI), associated with high in-hospital mortality and poor long-term survival. We have analyzed the incidence, resource utilization, short- and long-term outcomes, and predictors of dialysis after percutaneous coronary interventions. We(More)
BACKGROUND Stroke associated with percutaneous coronary intervention (PCI) is an infrequent although devastating complication. We investigated the incidence, predictors, and prognostic impact of periprocedural stroke in unselected patients undergoing PCI. METHODS AND RESULTS A total of 9662 patients who underwent 12 407 PCIs between January 1990 and July(More)
CONTEXT Acute ST-segment elevation myocardial infarction (STEMI) is a leading cause of morbidity and mortality. In experimental models of MI, erythropoietin reduces infarct size and improves left ventricular (LV) function. OBJECTIVE To evaluate the safety and efficacy of a single intravenous bolus of epoetin alfa in patients with STEMI. DESIGN, SETTING,(More)
BACKGROUND Familial Mediterranean fever is an autosomal-recessive disease characterized by acute attacks of fever with sterile peritonitis, pleurisy, or synovitis. The biochemical basis of the disease is unknown, but determining the chromosomal location of the gene for the disorder should be a first step toward defining the biochemical events. METHODS AND(More)
The heterogeneity in the degree of collateralization among patients with coronary artery disease (CAD) is poorly understood. We sought to determine whether chronic subclinical inflammation is related to coronary collateral development in patients with chronic stable angina pectoris and obstructive CAD. High-sensitivity C-reactive protein (CRP) levels were(More)
We aimed to determine the optimal adjunctive anticoagulation regimen for percutaneous coronary intervention (PCI) in patients presenting with acute coronary syndrome (ACS) initially treated with fondaparinux. The optimal adjunctive anticoagulation regimen for PCI in these patients is unclear. In this open-label, prospective, randomized, multicenter pilot(More)
OBJECTIVES The purpose of this study was to assess the impact of body mass index (BMI) on the short- and long-term outcomes after percutaneous coronary intervention (PCI). BACKGROUND Obesity is associated with advanced coronary artery disease (CAD). However, the relation between BMI and outcome after PCI remains controversial. METHODS We studied 9,633(More)
Distal embolization may decrease myocardial reperfusion after primary percutaneous coronary intervention (PCI). Nonetheless, results of previous trials assessing the role of distal protection during primary PCI have been controversial. The Protection of Distal Embolization in High-Risk Patients with Acute ST-Segment Elevation Myocardial Infarction Trial(More)
We describe a patient who developed a large aneurysm of saphenous vein graft to the right coronary artery with a fistulous communication to the right atrium. The presence of a fistulous communication of a saphenous vein graft aneurysm after coronary bypass surgery to one of the heart chambers is extremely rare. The diagnosis was made by coronary angiography(More)
