Cardiorespiratory fitness is inversely associated with a high risk of cardiovascular disease, all-cause mortality, and mortality attributable to various cancers. It often estimated indirectly using mathematical formulas for estimating oxygen uptake. Cardiopulmonary exercise testing, especially uptake, represents the "gold standard" assessing capacity. The purpose this report was develop reference standards capacity by establishing cardiorespiratory values derived from cardiopulmonary testing...
Resumo Fundamento: O manejo da angina instável (AI) é um desafio devido ao seu diagnóstico subjetivo e à sua escassa representação em ensaios clínicos randomizados que determinem as práticas atuais. Objetivos objetivo deste estudo identificar os principais fatores associados indicação de estratificação invasiva ou não nessa população avaliar às alterações nos exames estratificação. Métodos: Coorte retrospectiva pacientes internados por AI, período 20 meses consecutivos. Para estratégia...
FUNDAMENTO: A doença cardiovascular é a principal causa de morbi-mortalidade nos diabéticos. isquemia do miocárdio freqüentemente assintomática levando ao diagnóstico tardio e pior prognóstico. Sabe-se que mulher diabética tem risco morte maior em relação sexo masculino. OBJETIVO: Avaliar prevalência arterial coronariana (DAC) diabéticas assintomáticas. Comparar os resultados teste ergométrico (TE), cardiopulmonar (TCP) da cintilografia sob estímulo farmacológico com dipiridamol (CM) achados...
Myocardial ischemia may occur during an exercise session in cardiac rehabilitation programs. However, it has not been established whether is elicited when prescription based on heart rate corresponding to the anaerobic threshold as measured by cardiopulmonary testing. Our objective was determine incidence of myocardial programs according perfusion SPECT threshold. Thirty-nine patients (35 men and 4 women) diagnosed with coronary artery disease angiography stress technetium-99m-sestamibi...
To assess the clinical significance of transient ischemic dilation left ventricle during myocardial perfusion scintigraphy with stress/rest sestamibi.The study retrospectively analyzed 378 patients who underwent sestamibi, 340 whom had a low probability having ischemia and 38 significant defects. Transient was automatically calculated using Autoquant software. Sensitivity, specificity, positive negative predictive values were established for each value dilation.The groups defects were,...
To establish the degree of association between cardiovascular risk factors and presence coronary artery disease (CAD) in a group patients undergoing myocardial perfusion scintigraphy (MPS).The study included 7183 who had undergone MPS. Using logistic regression analysis odds ratios for following were evaluated: age, gender, family history, body mass index, smoking, dyslipidemia, diabetes mellitus (DM) systemic hypertension. Indicators CAD defined as: infarction, revascularization,...
Background: Cardiovascular disease is a leading cause of death in the world and Brazil.Myocardial scintigraphy an important noninvasive method for detecting ischemia symptomatic patients, but its use asymptomatic ones or those with atypical symptoms yet to be defined.Objective: To verify presence major cardiac events patients (atypical chest pain dyspnea) that underwent myocardial (MS), over period 8 years.Secondary objectives were identify risk factors associated abnormalities possible...
The most widely used data for cardiorespiratory fitness (CRF) referrals are from the Cooper Clinic, which uses calculated maximal oxygen uptake (VO2max) values.To develop CRF values cardiopulmonary exercise testing (CPX) in a Brazilian population with high socioeconomic level and free of structural heart disease. VO2max results were compared Clinic FRIEND Registry data.CPX consecutive individuals between January 1,2000, May 31,2016 this study. Inclusion criteria were: by pre-specified...
BACKGROUND: ISCHEMIA (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches) did not find an overall reduction in cardiovascular events with initial invasive versus conservative management strategy chronic coronary disease; however, there were participants who underwent angiography early postrandomization (within 6 months). Identifying factors associated will inform clinical decision-making patients disease. METHODS: Factors independently performed...
Abstract Background: The management of unstable angina (UA) presents a challenge due to its subjective diagnosis and limited representation in randomized clinical trials that inform current practices. Objectives: This study aims identify key factors associated with the indication for invasive versus non-invasive stratification this population evaluate test results. Methods: retrospective cohort included patients hospitalized UA over consecutive 20-month period. To assess strategies, were...
Some patients present an overestimated left ventricular ejection fraction (LVEF) on electrocardiogram-gated myocardial scintigraphy (gated SPECT).To establish the relationship between biological factors and LVEF.We selected 3838 who underwent gated SPECT May 20, 2000 September 16, 2005 with normal perfusion images LVEF > or =50%. The following variables were analyzed: gender (29.4% females 70.6% males), age (from 20 to 94 years - mean: 56 years), weight 33.5 150 kg 79.6 kg), height 138 220...
Restenosis after primary percutaneous coronary intervention (PPCI) remains an important clinical problem, even with stent implantation. The ability of noninvasive testing to diagnose restenosis has had only inconsistent demonstration.Our objective was evaluate the exercise treadmill (ETT) and myocardial perfusion imaging (MPI) in patients treated by PPCI within 12 hours ST-elevation infarction (STEMI).From August 2003 January 2006, 64 (mean age 56.2±10.2 years, 53 males) were enrolled PPCI....
Fundamento: No período pós-menopausa, a presença dos fatores de risco para doença arterial coronária (DAC) aumentam.Entretanto, não é bem estabelecida diferença prevalência isquemia miocárdica em mulheres pré/pós-menopausa com múltiplos DAC.Objetivos: Comparar na cintilografia perfusão sestamibi-99m Tc (CPM) nos períodos e avaliar se menopausa pode ser considerada fator preditor independente DAC.Métodos: Analisamos, retrospectivamente, 500 CPM pré/pós-menopausa, cardiovascular.A análise...
OBJETIVO: Avaliar quando se devem realizar exames de cintilografia perfusão do miocárdio (CPM), baseando-se em informações objetivas obtidas teste ergométrico e da análise dos fatores clínico-epidemiológicos para doença arterial coronária (DAC). MÉTODOS: Foram submetidos a CPM 2.100 pacientes que foram classificados segundo o resultado cintilografia, escore Duke clínico-epidemiológico, baseado Framingham. Os com positiva acompanhados fim definir os resultados eram verdadeiros positivos....
Background: The use of myocardial perfusion scintigraphy in asymptomatic patients remains restricted to very specific clinical situations, many which are addressed the appropriate criteria (AUC) for scintigraphy. Objective: To critically analyze application these indicating tests performed Dante Pazzanese Institute Cardiology, a population that is notably at high cardiovascular risk. Methods: study selected undergoing investigate ischemia.Indications were classified as appropriate,...
