BACKGROUND Few data exist regarding angiographic predictors of radial artery patency for coronary bypass grafting, and the benefit of calcium antagonists is not clear. METHODS One hundred fifteen patients were studied who had myocardial revascularization with the radial artery plus internal mammary and vein grafts with 3.5 +/- 1.1 grafts per patient.(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)
Let F be a field with 2 = 0 and φ =¿ a1, . . . , an À an n-fold anisotropic bilinear Pfister form over F with function field F (φ). In this paper we compute ker[In F /I n+1 F → In F (φ)/I n+1 F (φ)] where IF ⊂ W (F ) is the maximal ideal in the Witt ring W (F ) of F . We use this computation to prove a n-linkage property of the subfields F (a1, . . . , an).
Acute ST-segment–elevation myocardial infarction (STEMI) is a global source of mortality and morbidity and consequently is one of the most active areas of applied research. In the face of multiple reports of new combinations of medical and interventional therapies, the challenge to the clinician is both to understand data from key clinical trials and to(More)
OBJECTIVE To evaluate the effects of glucose-insulin-potassium (GIK) therapy on infarct size and left ventricular function when used as an adjuvant therapy to primary angioplasty. DESIGN Prospective, randomized, double-blind, placebo-controlled study. SETTING Cardiac intensive care unit at a university hospital. PATIENTS Thirty-seven patients with(More)
We have treated 28 patients (pts) with malignant hematological diseases with allogeneic bone marrow transplantation (BMT). 18 pts had acute lymphoblastic (ALL) and non lymphoblastic leukemia (ANLL), 5 chronic myeloid leukemia (CML), 2 severe aplastic anemia (SAA), 1 myelodisplasia, 1 Fanconi's anemia and 1 advanced Non Hodgkin's lymphoma. All but three(More)
AIMS Recent studies have shown that coronary cyclic flow variations (CCFV) is a platelet-related phenomenon that occurred following reperfusion. Although CCFV predicts acute complications following thrombolytic therapy, its impact following percutaneous coronary interventions (PCI) has not been evaluated yet. METHODS AND RESULTS One hundred and thirty-one(More)
Lippes Loop D or Copper T-200 devices were randomly assigned to 400 women in Santiago, Chile, none of whom had been recently pregnant, in the effort to test the relationship between IUD use and anemia and the effect of daily iron supplements on hematocrit levels in conjunction with IUD use. The mean age for the acceptor group was 25.4; the mean parity was(More)
