1. Cintilografia de perfusão miocárdica na investigação da isquemia silenciosa em pacientes diabéticos assintomáticos / Myocardial perfusion scintigraphy in the detection of silent ischemia in asymptomatic diabetic patients
Introdução: A doença arterial coronariana (DAC) é frequentemente assintomática em pacientes diabéticos, o que faz os testes não-invasivos serem uma ferramenta essencial para a detecção precoce da doença. O objetivo deste estudo foi avaliar a perfusão miocárdica de pacientes com diabetes mellitus tipo 1 (DM1) e tipo 2 (DM2) assintomáticos, sem di

2. Isquemia silenciosa e arritmias ventriculares são preditores independentes de evenos no pós-infarto do miocárdio de baixo risco
pós-infarto agudo do miocárdio (IAM) têm mostrado baixo valor preditivo positivo quando estudados isoladamente. A possibilidade da Eletrocardiografia Dinâmica de 24 horas (ECGD) fornecer dados referentes a isquemia silenciosa (IS), arritmias ventriculares e modulação autonômica do coração pelo estudo da variabilidade da freqüência cardíaca (VFC),

3. Transradial approach for coronary interventions
OBJECTIVE: To assess the feasibility and safety of coronary interventions performed through the radial artery. METHODS: We studied 103 patients with ages from 38 to 86 years (57±8.7), 90 (87%) males, and: radial pulse with a good amplitude, presence of ulnar pulse, a good collateral flow through the palmar arch assessed with the Allen's test. RESULTS: The v

4. Does a circadian variation occur in myocardial ischemia over 48 hours in patients with unstable angina?
OBJECTIVE: To study the incidence of and variation in myocardial ischemia over 48 hours in patients with unstable angina. METHODS: Thirty-nine patients with unstable angina underwent long-term electrocardiography for 48 hours. The number of events and the period of time of ischemia (in minutes) were analyzed for the 48 hours, in two periods of 24 hours, and

5. Safety and efficacy of angioplasty with intracoronary stenting in patients with unstable coronary syndromes. Comparison with stable coronary syndromes
OBJECTIVE: To assess safety and efficacy of coronary angioplasty with stent implantation in unstable coronary syndromes. METHODS: Retrospective analysis of in-hospital and late evolution of 74 patients with unstable coronary syndromes (unstable angina or infarction without elevation of the ST segment) undergoing coronary angioplasty with stent placement. The

6. Isquemia cerebral silente
Brain ischemia may be the result of atherosclerotic disease of the cerebrovascular system. It is known that some extracranial ischemic vascular accidents may occur in areas of lesser clinical importance or may not be realized by the patients or be noticed by his surrounding family. The aim of this study is to assess the occurence of these silent assymptomati

9. Myocardial infarction mediated by endothelin receptor signaling in hypercholesterolemic mice
Myocardial infarction is linked to atherosclerosis, yet the sequence leading from silent coronary atherosclerosis to acute myocardial infarction has remained unclear. Here we show that hypercholesterolemic apolipoprotein E−/− low density lipoprotein receptor−/− mice develop not only coronary atherosclerosis but also myocardial infarction. Exposure of

10. Mycotic embolism and embolomycotic aneurysms. Neglected lessons of the past.
During the past decade, nine patients with bacterial endocarditis have required management of mycotic emboli and/or aneurysms in this center. In these patients, 25 separate mycotic emboli or aneurysms were identified. Among these were four visceral, 11 lower extremity, one aortic, one hypogastric, and eight cerebral lesions. Multiple sites were involved in s

11. Cardiac evaluation and risk reduction in patients undergoing major vascular operations.
Occult coronary artery disease often accompanies symptomatic peripheral vascular disease and has an important effect on survival. Most perioperative and late fatalities after peripheral vascular operations are due to cardiac causes. Noninvasive cardiac testing can identify patients at increased risk for postoperative cardiac complications, although controver

12. Discharge of the hypoglossal nerve cannot distinguish eupnea from gasping, as defined by phrenic discharge, in the in situ mouse
If normal, eupneic breathing fails, gasping is recruited. Serotonin was proposed as essential for gasping, based on findings using an in vitro mouse preparation. This preparation generates rhythmic activities of the hypoglossal nerve that are considered to be akin to both eupnea and gasping. In previous studies, gasping of in situ rat and mouse preparations
