Estudo comparativo da identificacao de isquemia miocardica pela cineventriculog...

Objective – To evaluate and compare the usefulness of cineventriculographies, before and after nitrate use, to technetium-99m sestamibi scintigraphy for the identification of myocardial ischemia. Methods – Twenty-six patients were studied at basal conditions and 5 minutes after intravenous administration of isosorbide mononitrate (0.3mg/kg), to evaluate the performance and regional wall motion of the left ventr...

Seriam as apolipoproteinas A e B mais eficientes do que as lipoproteinas na inv...

Objective – To evaluate whether apolipoproteins A-I (Apo A-I) and B (Apo B) have, higher ensitivity (SN), specificity (SP) and positive predictive value (PPV) than lipoproteins (LP), total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL), and triglycerides (TGL) in assessing the risk of coronary heart disease (CHD). Methods – This is a transver...

Comparação da aterosclerose coronaria em pacientes com infarto do miocardio e a...

Objetivo - Comparar a gravidade da doença coronária e a presença de fatores de risco cardiovasculares entre pacientes com angina e infarto do miocárdio (IM). Métodos - Estudaram-se 62 pacientes com IM e 129 com angina, através de cineangiocoronariografia, avaliando- se a oclusão (lesão de 99% ou 100%), a severidade (escore de 0 a 5 de acordo com o número de vasos afetados) e a extensão (3 grupos com diferentes ...

Objetivou-se avaliar o nível de conhecimento e algumas atitudes preventivas em relação à leishmaniose visceral em Belo Horizonte, Minas Gerais, Brasil, em 2006. Foi feito um estudo de caso-controle, com visitas domiciliares e questionário semi-estrurado. Comparou-se dois grupos: (1) 82 casos humanos de leishmaniose visceral ocorridos em 2004 e (2) 164 controles, constituídos por vizinhos dos casos. A leishmanio...

Black carbon contents and distribution in sediments from the southeastern Brazi...

The concentration of black carbon (BC), as well as the relative contribution of BC to total organic carbon, was determined for the first time in sediments from Guanabara Bay. BC was quantified by a thermal oxidation method (CTO-375) and total organic carbon by dry oxidation. Sedimentary organic carbon showed a large range in concentrations (0.82 to 10.3%), but it was possible to define distinct regions of the B...

OBJECTIVE: To evaluate and compare the usefulness of cineventriculographies, before and after nitrate use, to technetium-99m sestamibi scintigraphy for the identification of myocardial ischemia. METHODS: Twenty-six patients were studied at basal conditions and 5 minutes after intravenous administration of isosorbide mononitrate (0.3mg/kg), to evaluate the performance and regional wall motion of the left ventric...
