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)

A cute 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)
This paper is intended to give a survey in the algebraic theory of quadratic forms over fields of characteristic two. The relationship between differential forms and quadratics and bilinear forms over such fields discovered by Kato is used to reduced some problems on quadratics forms to concrete questions about differential forms, which in general are(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)
Hemangiopericytoma is an infrequent tumor of vascular origin derived from Zimmermann's pericyte cells. It is generally seen in adults of both sexes and its major risk is late recurrence, that occurs in up to 50% of cases. Its spread pattern is principally hematogenous. The management of the disease is similar to that of other sarcomas. Surgical treatment(More)
BACKGROUND In large series, nearly 60% of admissions for suspected acute coronary syndrome (ACS) had a non-coronary etiology of the pain. However, short term mortality of non recognized ACS patients, mistakenly discharged from the emergency room is at least twice greater than the expected if they would had been admitted. The concept of a chest pain unit(More)
